“…Their study showed that the coating can be deposited on practically every kind of filtering media and is able to completely reduce the titre of SARS-CoV-2 to zero. Kumar et al [205] also investigated the potential of photodeposited Ag nanoparticles to destroy SARS-V-2 on the surface of fabrics. The fabrics were shown to be durable during washing cycles and exhibit strong antimicrobial performance, with 97% annihilation of the SARS-CoV-2 virus.…”

International interest in metal-based antimicrobial coatings to control the spread of bacteria, fungi, and viruses via high contact human touch surfaces are growing at an exponential rate. This interest recently reached an all-time high with the outbreak of the deadly COVID-19 disease, which has already claimed the lives of more than 5 million people worldwide. This global pandemic has highlighted the major role that antimicrobial coatings can play in controlling the spread of deadly viruses such as SARS-CoV-2 and scientists and engineers are now working harder than ever to develop the next generation of antimicrobial materials. This article begins with a review of three discrete microorganism-killing phenomena of contact-killing surfaces, nanoprotrusions, and superhydrophobic surfaces. The antimicrobial properties of metals such as copper (Cu), silver (Ag), and zinc (Zn) are reviewed along with the effects of combining them with titanium dioxide (TiO2) to create a binary or ternary contact-killing surface coatings. The self-cleaning and bacterial resistance of purely structural superhydrophobic surfaces and the potential of physical surface nanoprotrusions to damage microbial cells are then considered. The article then gives a detailed discussion on recent advances in attempting to combine these individual phenomena to create super-antimicrobial metal-based coatings with binary or ternary killing potential against a broad range of microorganisms, including SARS-CoV-2, for high-touch surface applications such as hand rails, door plates, and water fittings on public transport and in healthcare, care home and leisure settings as well as personal protective equipment commonly used in hospitals and in the current COVID-19 pandemic.

“…Recently, numerous papers have been devoted to the impact of silver coatings and nanoparticles on SARS-CoV-2 [47] , [48] , [49] , [50] . In the works [47] , [48] , [49] , [50] , where AgNPs of different sizes and concentrations were tested, it was shown that nanoparticles of diameter around 10 nm are effective in inhibiting extracellular SARS-CoV-2 at concentrations ranging between 1 and 10 ppm, while cytotoxic effect for cells was observed at concentrations of 20 ppm and above. Antiviral tests for cotton fabric surface with photodeposited 10 nm AgNPs exhibited a specific viral reduction of 97 % for SARS-CoV-2 [48] .…”

Sputtered coatings of silver nanocluster/ silica composite that were deposited on FFP3 masks showed a reduction in virus infectivity of one order of magnitude for coatings containing a lower silver concentration, and the complete removal of the infectivity at a higher silver concentration [49] .…”

“…Their bactericidal effect has prompted researchers in the field of virucides to assess whether these particles also have a virucidal effect [ 24 ]. AgNPs can effectively inhibit RNA and DNA viruses in vitro, such as human immunodeficiency virus, HIV-1, hepatitis B, Tacaraibe, adenovirus, parainfluenza virus, and influenza virus (H3N2) [ 25 , 26 , 27 , 28 , 29 ]. Studies have shown that AgNPs mainly exert their virucidal effect through two mechanisms.…”

Coronavirus disease 2019 (COVID-19) has spread rapidly and led to over 5 million deaths to date globally. Due to the successively emerging mutant strains, therapeutics and prevention against the causative virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are urgently needed. Prevention of SARS-CoV-2 infection in public and hospital areas is essential to reduce the frequency of infections. Silver nanoparticles (AgNPs) with virucidal effects have been reported. Therefore, we investigated the virucidal activity and safety of ten types of AgNPs with different surface modifications and particle sizes, in cells exposed to SARS-CoV-2 in vitro. The AgNPs could effectively inhibit the activity of SARS-CoV-2, and different surface modifications and particle sizes conferred different virucidal effects, of which 50-nm BPEI showed the strongest antiviral effect. We concluded that the efficacy of each type of AgNP type was positively correlated with the corresponding potential difference (R2 = 0.82). These in vitro experimental data provide scientific support for the development of therapeutics against COVID-19, as well as a research basis for the development of broad-spectrum virucides. Given the increasing acquired resistance of pathogens against conventional chemical and antibody-based drugs, AgNPs may well be a possible solution for cutting off the route of transmission, either as an external material or a potential medicine.
