(A) Synthesis of polymer brushes on a silicon substrate. Gold surface modification using thiol based initiators was also carried out. (B) Cyclic voltammogram of DNP-functionalized polymer brush. Inset: Cyclic voltammogram of hydroxylamine formed upon reducing DNP. Supporting electrolyte, 0.1 M H2SO4; sweep rate, 100 mV/s. (C) Frequency response of QCM crystal platform in PBS, pH 7.2, containing 1 mg/mL BSA solution at 25 °C. Rat anti-DNP IgG antibody solution (resultant concentration 11 nM) was added at 9000 s.
