Cytotoxicity and characterization of GO-PEI-yycG. a The cell viability were determined with CCK-8 after 48 h or 72 h of incubation with GO-PEI-ASyycG (Dulbecco’s modified Eagle’s medium supplemented with 10% fetal bovine serum was the blank control). b The particle size distributions were measured using dynamic light scattering. c The zeta potential of the GO-PEI-based ASyycG was assessed by a Malvern Zetasizer. d AFM confirmed the roughness parameters of GO, GO-PEI, and GO-PEI-ASyycG material films (n = 10,*p < 0.05). e SEM images of GO, GO-PEI, and GO-PEI-ASyycG material films
