Antibacterial and antiviral high-performance nanosystems to mitigate new SARS-CoV-2 variants of concern.

ABSTRACT

The increased severity of the COVID-19 infection due to new SARS-CoV-2 variants has resonated pandemic impact which made health experts to re-evaluate the effectiveness of pandemic management strategies. This becomes critical owing to the infection in large population and shortcomings in the existing global healthcare system worldwide. The designing of high-performance nanosystems (NS) with tunable performances seems to be the most efficient method to tackle infectious SARS-CoV-2 variants including recently emerged omicron mutation. In this direction, experts projects the versatile functionalized NS and their capabilities to mitigate SARS-CoV-2 propagation pathways by sensitization, antipathogenicity, photocatalysis, photothermal effects, immune response, developing efficient diagnostics assays or associated, selective biomarkers detection, and targeted drug delivery systems. To achieve these tasks, this opinion article project the importance of the fabrication of nano-enabled protective gear, masks, gloves, sheets, filtration units, nano-emulsified disinfectants, antiviral/bacterial paints, and therangostics to facilitate quarantine strategies via protection, detection, and treatment needed to manage COVID-19 pandemic in personalized manners. These functional protective high-performance antibacterial and antiviral NS can efficiently tackle the SARS-CoV-2 variants transmission through respiratory fluids and pollutants within water droplets, aerosols, air, and particulates along with their severe infection via neutralizing or eradicating the virus.
