Virucidal Effect of a Silver Nanocluster against Coronavirus SARS-CoV-2

Individual protective equipment do not possess an intrinsic antimicrobial/virucidal action. Masks, filters for air conditioning and for medical respiratory devices are susceptible to microbial/viral colonization. An article by Cristina Balagna et al in the journal Open Ceramics discuss the virucidal effect of materials and methods used to deposit a silver nanocluster composite on a facial FFP3 mask.

Virucidal Effect of Silver Nanoparticles

Individual protective measures do not completely mitigate the risk of contagion for healthcare staff and patients and the remaining population. All air filtering media are subject to microbial/virucidal colonization, and may limit microorganisms in the air. Air filtering media do not inactivate them or avoid their proliferation.

A more efficient approach to air filtering is needed to increase people protection. This will help to reinforce our health infrastructure and to protect the health of workers and patients.

Several studies have demonstrated the antimicrobial and antifungal behaviour of silver ions and nanoparticles. A preliminary evaluation of a silver nanocomposite in the antiviral effect towards Coronavirus SARS-CoV-2 (COVID-19) of a silver nanocomposite cluster was studied. A silver nanocomposite was deposited on a disposable facial FFP3 mask consisting of non-woven fabric.
