a The linear sweep stripping voltammetry (LSSV) curves of the Pd NPs/GCEs with different nanoparticle coverage measured in 0.01 M H2O2 (0.05 M PBS, pH = 7.4) at the scan rate of 0.05 V s−1. b The amperometric responses of the Pd NPs/GCEs with different nanoparticle coverage upon successive addition of H2O2 into gently stirred 0.05 M PBS (pH = 7.4) at −0.11 V. c The linear relationship between the response current and the H2O2 concentration
