Nano-particles against SARS-Cov2

The fast spread of COVID-19 in the world has raised as a serious threat for human health and global economy and is considered as a new challenge in medicine. In this paper, complete information is presented about treatment of viruses with the aid of nano-particles via attachment to the virus, release of reactive oxygen species, or destructive ions. In the present paper, present and potential applications of nano-technology to deal with viruses are reviewed, in the synthesis of various nano-based materials such as nano-delivery systems for treatment, personal protective equipment, and diagnostic devices. Here, the role of nano-materials in drug delivery is similar to other fields in nano-medicine; however, their intrinsic accumulation in macrophages is favorable for COVID-19. Nano-materials can be used in masks for longer usage times or air filters to ensure more protection. The new nano-based diagnostics are faster and sometimes more accurate than the traditional PCR method. The discussed nano-particle based methods for COVID-19 can also be considered for new viruses that will appear in future.
