Abstract

The present invention relates to an anti-viral nanoformulation suitable for diverse surface application in form of hydrogel based nanoemulsion, or an aerosol spray. The present invention discloses incorporation of nanomaterials such as functionalized carbon quantum dots (F-CQDs), copper nanoparticles (CuNPs) or silver nanoparticles (AgNPs) into the hydrogel (HG) scaffold to act as chemical barrier and anti-viral agent against SARS-CoV-2 or Escherichia coli: phage MS2. The nanoformulation is coated on personal protective equipment's (PPE) and different surfaces such as glass, steel and plastic to control viral infection including corona virus infection.
