Antiviral and antibacterial activity of the peptide-coated surfaces. (A) Virucidal activity of a PCN-coated SiO2 surface against a clean SiO2 surface (control). The data are representative of three biological repeats, each performed as duplicates. (B) Virucidal activity of P-, PC-, and PN-coated SiO2 surfaces against a clean SiO2 surface. (C) Bactericidal activity of a PCN-coated SiO2 surface against a clean SiO2 surface. The data are representative of three biological repeats, each performed as triplicates. (D) A photo of an agar plate from the antibacterial assay with bacteria from a clean SiO2 surface (top) and with bacteria from a PCN-coated surface (bottom). bd—below detection.
