2 ---- AI, PPE and nanotech

Artificial Intelligence Artificial intelligence may be used to simulate the propagation of viruses and forecast how an outbreak will likely develop. Effective resource allocation and the development of focused treatments are both possible with the help of this information. It helps researchers develop their applications related to pandemic situations. To improve viral disease detection and treatment, AI systems can examine patient data and medical imaging. Artificial intelligence can be used, for instance, to spot patterns in chest X-rays that might point to a COVID-19 infection [13]. Artificial intelligence can be used to find prospective medication candidates and forecast how they would interact with viral proteins. This can help find new treatments for viral illnesses and hasten the drug discovery process. It can be used to identify the most promising vaccine candidates and predict how they may interact with the immune system. This information can be used to develop more effective vaccines and improve vaccination strategies. The emerging uses of biomedical science in AI for pandemic control and prevention could fundamentally alter how we recognize, identify, and treat viral diseases. Artificial intelligence will likely become an even more potent weapon in the fight against pandemics as technology advances [14]. Personal Protective Equipment Personal protective equipment, which gives healthcare professionals and other essential personnel the ability to protect themselves against viral infections, has become an essential tool in pandemic prevention and control. The development of materials PPE is resistant to viruses and bacteria; these materials can increase or decrease PPE's effectiveness. New materials that can be used in PPE, such as fabrics that risk transmission, are being developed by biomedical scientists. Biomedical researchers are also creating PPE with improved fit and comfort which are easier to wear and more comfortable, like masks that don't irritate the skin or cause glasses to fog up. This can lower the risk of transmission and increase compliance with PPE requirements. Self-cleaning materials, like masks that are coated in a virus-killing substance, are being developed. This can increase PPE's effectiveness, lessen the need for frequent replacements, and have advanced sensors to monitor vital signs and spot early signs of infection. Biomedical researchers are creating sensors that can be incorporated into PPE. By doing this, viral diseases can be treated more effectively and earlier. They are also creating PPE that can be modified to meet specific needs, like masks that are made to fit the wearer's face. This can lessen the risk of transmission and increase the efficiency of PPE [15]. Nanotechnology Biomedical science and nanotechnology are two fields that have a lot of potential for cross-disciplinary collaboration and innovation. Innovative strategies for COVID-19 prevention and control have been developed as a result of the fusion of biomedical science and nanotechnology. Some examples of how these two fields have worked together to combat pandemics such as COVID-19 are as follows: With the help of nanotechnology, SARS-CoV-2 is being fought through infection prevention, detection, and treatment. Nanotechnology is a powerful tool with the potential to lower infections because it plays a significant role in the prevention, diagnostics, and therapeutic strategies for COVID-19 management. Among these strategies are the development of antiviral therapeutics or vaccines to introduce antiviral agents into the human body, diagnostic instruments for prompt, accurate, and focused diagnosis, and preventive measures and disinfectants based on nanomaterials. Nanomaterials, like metal nanoparticles, have a high surface-to-volume ratio because they are frequently smaller than one micrometer. Scientists are looking into developing vaccines using nanomaterials. Masks frequently contain nanomaterials like nanofibres and nanofibre webs to reduce the dispersion of large respiratory droplets and shield staff from patient-transmitted droplet transmission [16]. High-performance filtering masks (filtering face piece 2 (FFP2), FFP3, and N95) use a filtering face piece that combines an electrostatic charge and a web of polypropylene microfibers. By using filter materials like nanofibres and nanofibre webs and treating the filter surfaces with antimicrobial substances, the effectiveness of masks in fighting viruses and other microbes has been improved. The hydrophilic biocide film and partially gelled submicron polypropylene nanofibres used in the nanofibre filtering facepiece respirators (FFPR) effectively rendered pathogens inactive. Nanomaterials have also been used to create medical gloves for COVID-19 protection in addition to the mask. Due to the antibacterial properties of silver nanoparticles, for instance, some gloves have been created. It has been demonstrated that the veridical activity of silver nanoparticles (AgNPs) exists. Angiotensin-converting enzyme 2 (ACE2) receptors allow COVID-19 viruses to enter cells, so lowering ACE2 levels could help cut down on the number of infections. It was suggested that using nanotechnology in the gloves to catch the viruses before they enter the cells would be very beneficial [4]. Numerous opportunities exist for improving practicality and ensuring sanitation, thanks to nanotechnology. These nanomaterials include engineered water nanostructures and metallic nanoparticles, primarily titanium dioxide (TiO2) and AgNPs, which have antiviral properties and aid in COVID-19 protection. Deionized water, electrolyzed water, and hydrogen peroxide solutions for microbe inactivation are some of the active ingredients used to make engineered water nano-disinfectants. These nanosanitizers' effectiveness at eliminating microbes from surfaces and the environment was tested. Nanoparticles have drawn a lot of interest in the development of vaccines because of their simple functionalization, controlledrelease properties, photothermal and magnetic properties, and tunable size. They are now widely used by researchers to deliver targeted vaccines to immune cells like dendritic cells (DCs). Selective targeting of DCs with nanomaterials has been achieved using a variety of techniques, demonstrating great promise for the development of low-dose vaccines [17]. Similar to this, nucleic acids were delivered to the target cell using lipid-based nanoparticles. It enables the production of vital viral proteins for immunization or the inactivation of vital viral target genes. By inserting a plasmid containing a DNA sequence encoding the antigen(s) into the appropriate tissues, one vaccination technique has been developed. These vaccines have a problem with insufficient cell delivery. Nucleic acidbased therapeutic products have been administered using cationic lipid nanoparticles to address this problem [16]. The potential for biomedical applications of protein nanoparticles is great. The majority of them are obtained using recombinant technologies. Researchers created self-assembling protein nanoparticles (SAPNs) by oligomerizing monomeric proteins. It was demonstrated that SAPNs could be modified to produce a diameter resembling that of viruses, and as a result, they are recognized as a potential candidate for a vaccine against respiratory viruses. One of the most widely used nanomaterials for quick diagnostics is gold nanoparticles (AuNPs). For instance, in one study, gold nanoparticles were used to identify target viruses' double-stranded DNA (dsDNA). And nanomaterials based on carbon have been widely used to create platforms for COVID-19 diagnostics. Using carbon-based nanomaterials as COVID-19 antiviral therapeutics is possible [18]. Nanozymes are synthetic enzymes made of nanomaterials that function just like natural enzymes do. Because of their exceptional catalytic abilities, quick response times, and capacity for self-assembly, nanozymes are frequently used in the diagnosis and treatment of diseases. Antiviral therapy has a new window of opportunity thanks to nanotechnology. Nanoparticles are adaptable vectors for the targeted delivery of specific therapeutic drugs and viruses due to their flexibility. To improve drug bioavailability, drug delivery, and targeted antiviral activity, organic nanoparticles have been used to deliver antiviral medications like acyclovir, zidovudine, efavirenz, and dapivirine. Exosome delivery to the target cell for therapeutic purposes has recently attracted a lot of attention. They have been introduced as potential biological nanocarriers for COVID-19 treatment in several clinical applications. Coronavirus disease (COVID-19) has also been treated with peptide inhibitors [19]. Overall, the relationship between biomedical science and nanotechnology has led to the development of innovative solutions for pandemic prevention and control. These emerging applications have the potential to not only combat the current pandemic but also be useful for future disease outbreaks. However, it is important to continue to evaluate their safety and effectiveness through rigorous testing and research.
