Provides a brief outline on virus and viral infections and gives insight into various viruses and viral infections that have affected the human population for a long time. Explains the origin, spread, virulence, and effect of emerging infectious diseases (SARS, MERS, COVID) on the socio-economic structure of human population. Highlights nanotechnological solutions in combating viral infections. Showcases the role of nanotechnological tools to overcome COVID-19. Nanotechnology is the present age technology being used in different areas of medical science including drug delivery, gene therapy, antimicrobials, biosensors, and bio-labelling. Nanoparticles play a competent role as an anti-infection agent and thus are supposed to act as efficient antiviral agents. Nanotechnological applications in virology highlights nanotechnological solutions in combating viral infections. It showcases the role of nanotechnological tools to overcome COVID-19.
Nanotechnological applications in virology is composed of five sections. Section I explores the use of nanoparticles-based technologies to fight against viruses, as well as the use of nanoparticles in the preparation of nano masks and as sanitizing agents. The role of nanotechnology against HIV, Hepatitis, Influenza, Herpes, Ebola and Zika using rapid detection and diagnostic techniques has been included in Section II. Section III includes a brief description of SARS, MERS and the novel Corona virus and the recent advancements in its treatment process. Section IV includes the formulation of novel nano-vaccines for the treatment and control of viral infections like HIV, Hepatitis, and COVID-19. Toxicological studies of nanoparticles have been included in Section V. provides the readers with a brief overview about the global scenario of viral infections specifically Coronavirus and how nanotechnology can serve as a promising technology to deal with this global health threat.
The role of nanoparticles in the development of diagnostic tools for rapid testing, as targeted drug delivery agents, the development of novel vaccines and other aspects related to nanoparticles are critically discussed to highlight the use of nanotechnological solutions in combating viral infections.
