The exciting potential of nanoscale probes thus represents a significant leap forward in the field of molecular diagnostics and cellular biology. Nanotechnology holds significant promise in enhancing the sensitivity and integration of analytical methods, allowing for a more coherent evaluation of life processes. In particular, it can address the challenges associated with the therapeutic application of nucleic acids, which are large, negatively charged macromolecules. Due to their inherent physicochemical properties, nucleic acids face several biological barriers that hinder their effectiveness as therapeutic agents. These limitations include nuclease degradation, which results in the rapid breakdown of nucleic acids in biological environments; unfavorable pharmacokinetics and pharmacodynamics, which impair their distribution and efficacy in target tissues; and clearance via the reticuloendothelial system (RES), which leads to premature elimination from the bloodstream. Additionally, the ability of nucleic acids to permeate cellular membranes is compromised due to their size and charge, making it difficult for them to enter target cells effectively. Once inside, they must navigate intracellular trafficking to reach their designated sites for action, which further complicates their therapeutic application. Nanotechnology provides solutions to these challenges by enabling the design of nanocarriers that can encapsulate nucleic acids, protecting them from degradation and facilitating their transport within the body. These nanocarriers can be engineered to improve pharmacokinetics and pharmacodynamics, promoting longer circulation times and enhanced accumulation in target tissues. Moreover, nanocarriers can be modified with targeting ligands that enable them to bind specifically to receptors on target cells, thereby enhancing cellular uptake through endocytosis. This specificity not only increases the efficacy of nucleic acid delivery but also minimizes off-target effects. By overcoming these barriers, nanotechnology not only opens new avenues for the therapeutic use of nucleic acids but also enhances our ability to comprehensively analyze and manipulate complex biological processes at the molecular level, ultimately leading to innovative treatments for various diseases. Upon administration, nucleic acids, particularly RNA, face significant challenges due to the abundant presence of nucleases, such as 3' exonuclease and endonucleases, in biological compartments including plasma and tissues. These nucleases rapidly degrade RNA molecules, limiting their therapeutic potential and making them susceptible to swift inactivation before they can reach their intended targets. This degradation not only diminishes the efficacy of RNA-based therapies but also complicates their use in clinical settings, where maintaining RNA stability is crucial for therapeutic outcomes. Additionally, the pharmacokinetics and pharmacodynamics of RNA are further impaired by a rapid clearance mechanism through the kidneys, which quickly filters and excretes free RNA molecules from circulation. When RNA is associated with larger carriers, such as liposomes or polymeric nanoparticles, the liver becomes a primary site for clearance, exacerbating the problem of systemic distribution. This clearance occurs within minutes, leading to an acute systemic distribution phase that restricts the time available for the RNA to exert its therapeutic effect in target tissues. To overcome these hurdles, researchers are exploring various strategies to enhance the stability and bioavailability of RNA therapies. These strategies include the use of chemical modifications to confer nuclease resistance, the design of nanocarriers that shield RNA from degradation, and the incorporation of targeting moieties that facilitate selective uptake by target cells. Improving the pharmacokinetic and pharmacodynamic profiles of RNA is essential for achieving longer circulation times in the bloodstream, increasing tissue accumulation, and ultimately enhancing the therapeutic efficacy of RNA-based treatments. As advancements in drug delivery systems and nanotechnology continue to evolve, they hold great promise for maximizing the potential of RNA therapies in treating a variety of diseases, including cancer and genetic disorders. The reticuloendothelial system (RES) poses a significant barrier to the in vivo delivery of nucleic acids, primarily due to the highly efficient phagocytic activity of immune cells such as monocytes and macrophages. These cells are adept at recognizing and engulfing foreign particles, including nucleic acid formulations encapsulated in nanocarriers or liposomes. As a result, once nucleic acids are administered, they can be rapidly cleared from circulation, impeding their therapeutic efficacy and distribution to target tissues. This rapid clearance through the RES not only diminishes the half-life of nucleic acid-based therapies but also disrupts the intended pharmacokinetics needed for effective treatment. Consequently, overcoming this challenge necessitates innovative strategies that enhance the stealth properties of nucleic acid formulations, such as PEGylation or the use of biodegradable materials that can evade immune detection. Furthermore, tailoring the size, surface charge, and composition of nanocarriers can significantly influence their interaction with RES components, potentially improving the systemic availability of nucleic acids and extending their therapeutic window. As research in drug delivery systems advances, finding ways to effectively navigate the barriers presented by the RES will be crucial for the successful implementation of nucleic acid therapies in clinical practice. The COVID-19 crisis has unveiled the fundamental interdependence between public contributions and the advancement of medical innovations, particularly in the context of vaccine development.

This can include mechanisms such as equitable licensing agreements, transparent pricing strategies, and the promotion of open-source approaches to vaccine technology that allow broader access. Furthermore, governments and international organizations must emphasize the importance of global partnerships and solidarity in overcoming the pandemic, ensuring that innovations developed with public funding are accessible to all, particularly those in marginalized communities. The COVID-19 pandemic serves as a critical lesson in the need for a paradigm shift in how medical innovations are governed. It calls for an urgent reevaluation of the current models that prioritize profit over public health. Moving forward, it is essential to establish frameworks that foster collaboration between public and private sectors, ensuring that health innovations are developed and distributed equitably. Ultimately, the protection and promotion of public health must be paramount, requiring a commitment to dismantling existing barriers and redefining the terms of engagement in medical research and innovation. Through these changes, we can work toward a more just and equitable healthcare landscape, particularly in times of crisis. The ongoing challenges within the health and pharmaceutical sectors underscore that tinkering at the margins of the status quo will not yield the transformative solutions needed to address pressing public health issues. Current market-based policies, predominantly shaped by the interests of private corporations, have failed to generate essential health technologies that are universally accessible and affordable. The global response to crises such as the COVID-19 pandemic has highlighted the systemic flaws in these policies, showcasing significant gaps in the development and distribution of vaccines and therapeutics. Therefore, it is imperative to rethink and redesign research and development (R&D) and access policies that are no longer captive to a Western-dominated global health order. A shift toward needs-driven research and the production of pharmaceuticals is critical. This means prioritizing public health needs over market profits, emphasizing the principle of health as a commons rather than a commodity. Such an approach requires recognizing that healthcare technologies—including vaccines, medications, and medical devices—should be designed and developed with public health goals as their foremost priority. By organizing R&D around public needs, it becomes possible to ensure that innovations are directly relevant to the populations that require them most, rather than being dictated by market forces that predominantly serve wealthier nations or consumers. To realize this vision, we must establish transparent and equitable governance structures that facilitate collaboration between the public sector, private companies, and civil society. Ensuring transparency in funding, decision-making, and outcomes can foster greater accountability and trust among stakeholders. These collaborative arrangements should be designed to align the interests of private innovators with public health goals, incentivizing companies to prioritize accessibility and affordability in their R&D processes. For instance, public-private partnerships can be structured to require that the results of publicly funded research, whether in terms of patents, licensing, or distribution, are made available to all without exorbitant costs. Additionally, enhancing public capacities for R&D and manufacturing is essential. Governments and international organizations could invest in public sector research institutions and innovation hubs that prioritize health equity. By bolstering local production capabilities in low- and middle-income countries, it becomes possible to decentralize pharmaceutical production, reducing dependency on multinational corporations and ensuring that life-saving technologies are produced closer to the communities that need them. A holistic approach that includes diverse stakeholders will also help expand the dialogue around intellectual property rights, advocating for flexible frameworks that prioritize widespread access over strict commercialization. Models such as open-source pharmaceuticals could enable a more collaborative approach to drug development, allowing multiple entities to contribute to and benefit from innovations without the constraints imposed by proprietary rights. Ultimately, the transition from a market-driven model to one that actively invests in health as a shared global resource is crucial for sustainable change. By prioritizing the public good in health innovation, we have the potential to create a more equitable system that values human life over profit and ensures that essential health technologies are made available to all who need them. Embracing this fundamental shift is not just an ethical imperative but a pathway to a healthier, more just world, equipping us to better address the health challenges of today and tomorrow.

NDDS ( Noval Darug Delivary System ) :
The method by which a drug isdelivered can have a significant effect on its efficacy. Some drugs have an optimum concentration range within which maximum benefit is derived, and concentrations above or below this range can be toxic or produce no therapeutic benefit at all 1. On the other hand, the very slow progress in the efficacy of the treatment of severe diseases, has suggested a growing need for a multidisciplinary approach to the delivery of therapeutics to targets in tissues. From this, new ideas on controlling the pharmacokinetics, pharmacodynamics, non-specific toxicity, immunogenicity, biorecognition, and efficacy of drugs were generated. These new strategies, often called drug delivery systems (DDS), which are based on interdisciplinary approaches that combine polymer science, pharmaceutics, bioconjugate chemistry, and molecular biology. To minimize drug degradation and loss, to prevent harmful side-effects and to increase drug bioavailability and the fraction of the drug accumulated in the required zone, various drug delivery and drug targeting systems are currently under development Controlled and Novel Drug Delivery which was only a dream or at best a possibility is now a reality. During the last decade and half pharmaceutical and other scientists have carried out extensive and intensive investigations in this field of drug research. Among drug carriers one can name soluble polymers, microparticles made of insoluble or biodegradable, natural and synthetic polymers, microcapsules, cells, cell ghosts, lipoproteins, liposomes, and micelles. The carriers can be made slowly degradable, stimuli-reactive (e.g., pH- or temperature-sensitive), and even targeted (e.g., by conjugating them with specific antibodies against certain characteristic components of the area of interest). Targeting is the ability to direct the drug-loaded system to the site of interest. Two major mechanisms can be distinguished for addressing the desired sites for drug release.Active targeting is an advanced strategy used to ensure selectivity and specificity of SMART Nanosystem to the targeted site/organ/cells. Commonly, targeting of antitumor drugs to the cancerous tissue has become the main strategy to reduce the effects the drugs might have on healthy tissues. The technique of active targeting should be considered during preparation of the SMART noncolloidal system via functionalization of the surface of the carrier with ligands, which specially bind with its corresponding receptor on the surface of the targeted cell. Ligand receptor attachment can guarantee that the Nano system will be optimally delivered to the dis- eased cells rather than the surrounding healthy tissue . The attached ligand on the surface of the Nano system can be classified as several subtypes including antibodies or parts of their fragments, nucleic acids (aptamers), and various classes of peptides. These ligands bind with their specific receptors that are densely localized on the surface of tumour cells. This approach also ensures higher cellular uptake through the endocentric pathway. The affinity of binding between the ligand and the receptor which is overexpressed on the surface of the targeted cell is the most important factor affecting the delivery of the drug. After ligand—receptor interaction, two possible mechanisms might occur, the Nano system might start to release part of its encapsulated drug in the close proximity of the tar- get cells and act as sustained release drug reservoir or the intact Nano system is engulfed via endocytosis and the release begins inside the cell. The second mechanism is desirable to ensure efficient delivery of drug inside the cells. Recently, SMART NPs have been widely used as a Nano carrier drug delivery system for cancer therapy. The surface of SMART NPs is functionalized with specific ligands for active targeting These systems take advantage of the fact that tumorous cells
3D Printing:
3D printing, or additive manufacturing, has revolutionized manufacturing technology by significantly reducing product development cycles and enabling rapid prototyping. Originally devised to expedite the design process, these machines have found diverse applications across various fields, including engineering, medicine, design, science, education, market research, and art, showcasing their versatility and transformative impact on innovation and production.3D printing relies on complementary technologies such as Computer Aided Design (CAD), Computer Aided Manufacturing (CAM), and Computer Numerical Control (CNC) to create three-dimensional objects through a layered approach, starting from a digital file. Invented by Charles W. Hull in 1983, the initial process, known as stereolithography, utilized UV rays to cure photopolymers. The first step involves designing the product in CAD software or scanning an existing object to create a 3D digital model, which is then sliced into numerous horizontal layers for the printing process.3D printing commonly utilizes fine plastic or metal powder, with particle sizes as small as 20 micrometers, stored in cartridges or beds and spread in thin layers using a roller or blade. An array of nozzles then applies a binding agent according to the design specified in CAD, after which a new layer of powder is added, and the process is repeated with the build platform lowered accordingly. Upon completion, the finished part is removed from the surrounding unconsolidated powder, then cleaned and potentially finished. This technology excels at producing highly complex and customizable products, highlighting its versatility in manufacturing.
Types Of 3d Printing:
A 3D printer is a type of industrial robot. It can be classified on the basis of form of materials used to make model. The form of material can be solid, liquid and powder (1). The classification is given below:
SL was developed by 3D system, Inc. It is widely used process of rapid prototyping. In this process, firstly, STL file of the part/object is created in CAD software. The STL file contains details of each layer. Then the layering of liquid photopolymer is done on support material in the machine. Support material is required for the cavity or overhung parts in the object. The machine automatically generates support structure for the model under the construction. After layering, curing process is done with UV laser at specific locations. During curing process, solidification of polymer takes place. After that the platform is lowered by one layer thickness. The process of layering and curing continue till the part/ object is completed. Then, the object is taken out and the support material is removed manually. The object is then finished. Here UV light acts as catalyst for polymerization. SL process is selected when it is required to make visual prototypes for photoshoot, show fine details, market testing, checking 3D drawings, low volume production of complex geometries etc.
The technology was developed by S. Scott Crump in the late 1980s and was commercialized in 1990 by a company named Stratasys. In this process the object is built layer –by – layer from the bottom up by heating and extruding thermoplastic filament. The first step is to create 2D slice of the object with the help of AutoCad or any design software. The software also determines path to extrude the thermoplastic material and support material if needed. Then the material is fed into the temperature controlled extruder head, where it is converted into semi liquid state. The thermoplastic material is heated just beyond its Glass Transition temperature (Tg). The head extrudes fine filament of thickness in the range 0.254 mm and deposits in layers on a fixtureless base. Where a support or buffering is needed, the 3D printer deposits a removable material that acts as scaffolding. When layer is finished, it moves in the Z direction to the next layer. The layering process is done vey precisely and bonded and solidified. Once the process is complete, the support material is removed and the object is finished. Mainly polymeric materials such as Acrylonitrile Butadiene Styrene, Polylactic acid, Polycarbonate, Polyamide, Polystyrene etc. are used in FDM 3D printers. This technology is widely used in various industries such as aerospace, automotive, medical etc. apart from that it attracts a large number of professionals such as engineers, designers, educators and they can make any prototype or product for their requirements.
In this technology, two or more ink jets are used for spraying liquid polymers. For making object, photopolymer is used which is cured instantly in presence of UV light. Another jet can be used for support spraying support material, which is not cured by UV light. Support material is used for overhung parts. It is then removed after completion of the layering process by hand and water jetting. PlyJet 3D printing machine is used to create objects or parts which have very high details. The thickness of the horizontal layers can be as low as 16 micron and ultra-thin walls down to 0.6mm (0.024") depending on geometry. The limitation of this process is the objects or parts produced are weaker compared to the other process such as stereolithography and selective laser sintering. Here it is also possible to produce multi colored objects (1, 4, 5, 6). Companies have developed their own wide range of different materials in terms of properties to suit various needs. Materialse, a popular company provides 3D printing Solutions, offers two primary materials. They are VeroWhite Plus and TangoWhite Plus. VeroWhite Plus is a general purpose resin, available in white color and has very good mechanical properties. TangoWhite Plus is flexible rubber like resin, which has exceptional elongation at break and can be used as rubber like products. This company also offers a number of composite materials (5). Another company named Stratasys, also offers a vast array of materials which can work on Polyjet 3D printing machines. They vary in properties and colors. Stratasys also offers two Polyjet copolymers which simulate the functionality and appearance of Polypropylene.
SLS was developed and patented by Dr. Carl Deckard and academic adviser, Dr. Joe Beaman at the University of Texas at Austin in the mid-1980s. In this technology, the basic material is powdered form of metal, combinations of metals, polymer, combinations of polymers, combinations of metals and polymers, combinations of metals and ceramics are used. The particle sizes are in the order of 50 µm. The carbon di oxide laser beam fuses metal or polymeric power at specific locations as per the design. After completion of every layer, the powder bed is lowered by one layer thickness and a new layer of the material is applied on the top. The process is repeated until the part or object is completed. The process is carried out in an inert atmosphere to avoid oxidation. For metals, binders are used. The binder is removed after the process. (1, 3). Unlike FDM, SLS does not require any support material as the part which is being constructed, always remains surrounded by unsintered powder. A wide range of materials can be processed on SLS. These include polymers such as nylon (neat, glass-filled, or with other fillers) or polystyrene, metals including steel, titanium, alloy mixtures, and composites and green sand. The physical process can be full melting, partial melting, or liquid-phase sintering. Depending on the material, up to 100?nsity can be achieved with material properties comparable to those from conventional manufacturing methods (13). Other techniques of additive manufacturing are also available. These are 3DP, Prometal, Electron beam melting (EBM), Laminated Object Manufacturing LOM), Laser Engineering Net Shaping
