Copper Nanomaterials Derived Preventive Technologies for COVID-19 Pandemic: A Review

Copper has been well-known for its antimicrobial properties, killing microorganisms and viruses. Scientific evidence attests the potential of copper and copper nanoparticle’s derived surfaces to combat microorganisms and viruses in the surrounding environment. Coronavirus disease 2019 has affected people’s life and undermined the economy worldwide. There are many preventive measures in practice to combat coronavirus disease as per local, national and/or World Health Organization (WHO) guidelines. However, with reference to the antibacterial and antiviral potential of copper and copper nanoparticles, respiratory face masks, phone cases and hand sanitizers are developed by incorporating copper and copper nanoparticles and made available in pandemic time. In this review, copper and copper nanoparticle’s derived preventive technologies are summarised and discussed in detail.
