This proposal deals with the preparation of green chemicals-assisted sanitizer to disinfect pathogens including novel coronavirus. Large scale sanitizer will be prepared by using green chemicals (biopolymers, green solvents, and medicinal important phytochemicals), improving disinfecting activity for long time. Biocompatible nanomaterials generated from medicinal plants are going to mix with sanitizer liquids which could enhance the degree of disinfection activity without any side effect to host cells.
