Fig. 2From: RETRACTED ARTICLE: Plasma Protein Adsorption to Zwitterionic Poly (Carboxybetaine Methacrylate) Modified Surfaces: Chain Chemistry and End-Group Effects on Protein Adsorption Kinetics, Adsorbed Amounts and Immunoblotsa Adsorption of β-lactalbumin from PBS buffer (pH 7) for a time period of 2 h. a Amount of adsorption versus incubation time on (filled diamond) bare oxidized silica wafer (upward filled triangle) wafer modified with phosphonate initiator (downward filled triangle) wafer modified with TEMPO initiator (filled circle) wafer grafted with PCBMA-5 (Phospho) and (filled square) wafer grafted with PCBMA-5 (TEMPO). b β-la adsorption chart to various PCBMA surfaces and four different concentrations. All these values are statistically significant to silicar wafer grafted corresponding initiators (p < 0.001, one way ANOVA). Statistical analysis between surfaces varying spacer and end groups are shown in the figure with *p < 0.05 (one way ANOVA), **p < 0.001 (one way ANOVA). Data shown represent average ± 1 SD, n = 3Back to article page
