a) Schematic representation of intended interactions between G‐PGS‐C11 and SARS‐CoV‐2. While negatively charged polyglycerol sulfate interact with the positively charged domains of S on the surface of SARS‐CoV‐2, aliphatic chains penetrate into its membrane and disintegrate the virus. b) Schematic representation of the synthesis of G‐PGS‐Cx. Synthesis of G‐PGS derivatives with i) short (C6, C9) and ii) long aliphatic chains (C10, C11, and C12). G‐PGS, DMF, C₆H₁₃NH₂/C₉H₁₉NH₂/C₁₀H₂₁NH₂/C₁₁H₂₃NH₂/C₁₂H₂₅NH₂, triethylamine, 25–60 °C, 24 h. c–e) AFM images with enlarged parts showing typical size and height of graphene sheets, and highly resolved f–h) XPS spectra for G‐PGS‐C6, G‐PGS, and G‐PGS‐C12, respectively. Scale bars correspond to 100 nm.
