a Adsorption of HSA from PBS buffer (pH 7) for a time period of 2 h. a Amount of adsorption vs. 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 HSA 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 = 3
