(A) ECL, (B) CV and (C) EIS responses of (a) GCE, (b) Ru-SiO2@PEI/GCE (c) Au/Ru-SiO2@PEI/GCE, (d) anti-NSE/Au/Ru-SiO2@PEI/GCE, (e) BSA/anti-NSE/Au/Ru-SiO2@PEI/GCE, (f) NSE/BSA/anti-NSE/Au/Ru-SiO2@PEI/GCE. The ECL responses were measured in 0.1 M PBS (pH 7.5); Scan rate: 100 mV s−1. Scan potential: 0~1.35 V. CV and EIS were conducted in 0.1 M KCl solution containing of 5.0 mM [Fe(CN)6]3−/4−.
