(PLL-SWCNT2)-(PLL-Ab) assemblies equilibrated in buffer and in air incubator at 32°C for different time intervals for sensors with i) 90% PLL and ii) 93.7% PLL. After equilibration, sensor was subjected to BSA blocking step and then incubated with 50 pmol mL−1 Ag and tested amperometrically. Steady state amperometric response of PLL-SWCNT2-Ab/Ag was developed by addition of hydrogen peroxide (−0.3 V vs. SCE at 2000 RPM, 0.1 mM H2Q, 4 μM H2O2 injection). Response at zero time serves as control and is from fully assembled PLL-SWCNT2-(PLL-Ab)/Ag assembly with i) 90% PLL and ii) 93.7% PLL that was not exposed to buffer or air 32°C.
