PSB coating resists protein adsorption and cell adhesion (A) Protein adsorption comparison between bare, PSB, and PDA-PSB coated wafer. (B and C) 3T3 fibroblast cell attachment assay results for bare, PSB coated, and PDA-PSB coated wafer. Cyan (nuclei). For section A, N= 4 and for section B, N=8 for Bare, PSB and PDA-PSB groups. Data showed as mean ±SE; * indicates p<0.05.
