Summary of different antiviral surfaces.
| Antiviral materials | Surface features | Viruses | Incubation time | Result |
|---|---|---|---|---|
| Al 6063 alloy surfaces | Nanostructured surfaces, 23 nm ± 2 nm | Respiratory syncytial virus (RSV), rhinovirus (RV) | 24 h | More efficient against RV than RSV, 3 − 4 log10 reduction observed in viable virus. 100 |
| Al 6063 alloy surfaces | Nanostructured surfaces, 23 nm ± 2 nm | Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) | 6 h | Antiviral activity, 5 log reduction with no recoverable viable virus. 101 |
| PTFE nanoparticles thermally sintered to PP microfibers | Superhydrophobic low surface energy, multilength scale roughened textiles | Adenovirus type 4 and 7a | – | Reduced the attachment of HAdv4 and HAdv7a virions by 99.2 ± 0.2% and 97.6 ± 0.1%, respectively. 102 |
| Polyethylenimines (PEIs) derivatives | Hydrophobic polycationic coatings | Influenza (H1N1) virus | 30 min | Killed influenza virus with 100% efficiency, at least a 4-log reduction in the viral titer. 13 |
| PEIs | Hydrophobic polycationic coatings | Poliovirus, rotavirus | 30 min | Disinfected aqueous solutions of enveloped and non-enveloped viruses. 105 |
| QACs | Hyperbranched polymers with quaternary amines | Poliovirus Sabin1, influenza A (H1N1) virus | 1 h | Virucidal activity only against enveloped influenza A (H1N1) virus. 106 |
| QBEst, QBAm | Cationic polymeric coatings, zwitterionic structure | Influenza (H1N1) virus | 30 min | QBEst and QBAm coated surfaces reduced the viral burden by >1000- and >10 000-fold. 107 |
| Copper | CuO NPs impregnated into N95 masks | Human influenza A virus (H1N1), avian influenza virus | 30 min | Potent anti-influenza biocidal properties. 114 |
| Silver | PHBV films coated with AgNP fibers | FCV, MNV | 150 days | No infectious FCV, MNV titers decreased by 0.86 log. 116 |
