A comprehensive review on antimicrobial face masks: an emerging weapon in fighting pandemics

“…201 Among various nanoscale carbon derivatives, graphene, 202 graphene oxide, 203,204 and reduced graphene oxide 205 are employed to make antimicrobial fabrics effective against bacteria and viruses. 201,206,207 Laser-Induced Graphene (LIG) was discovered in 2014. The method uses an infrared laser scriber to convert carbonaceous materials into porous 3D graphene under an ambient environment.…”

Potential application of biomass derived graphene for COVID-19 pandemic

“…For instance, face mask incorporated graphene able to self-sterilizing, kills the virus and reusable. It is noteworthy that the effectiveness of face mask incorporated graphene against viruses is 99 % as compared to N95 face mask [41] . On top of that, a PPE that is layered with biomass-derived graphene able to prevent the transmission of COVID-19 since the material is hydrophobic [12] .…”

Viewpoint: How the Graphene Could Help to Decrease SARS-CoV-2 Spread?

“…Graphene is a two-dimensional (2D) sheet-like material with sp 2 hybridized carbon atoms configured in a hexagonal structure and its thickness is equivalent to an atom diameter [10,11]. Along with its derivatives, graphene oxide (GO) and reduced graphene oxide (rGO), graphene materials have been deeply studied and applied in various fields due to the presence of aromatic rings, free π-π electron and reactive functional groups [12,13]. Graphenebased materials provide the advantages of easy preparation and reusability.…”
