Fig 1: C-reactive protein (CRP) detection performance of the microfluidic platform: The Nyquist plots of EIS measurements and the calculated measured CRP concentrations (n = 3) in the detection of CRP spiked in (A,B) plasma and (C,D) whole blood samples.
Fig 2: (A) The schematic of the EC sensor functionalization protocol. It can be divided into five steps: (1) surface cleaning, (2) 11-MUA self-assembly, (3) EDC/NHS activation, (4) anti-CRP binding, and (5) BSA blocking step. (B) The Nyquist plots of EIS measurement at each functionalization step.
