Monodispersed Au nanoparticles decorated MoS2 nanosheets with enhanced peroxidase-like activity based electrochemical H2O2 sensing for anticancer drug evaluations

Abstract

The developed H₂O₂ sensor has excellent stability, reproducibility (RSD = 2.3 %, n = 6) and selectivity, realized the quantitative detection of H₂O₂ in cell lysate. Compared with commercial fluorescence detection kits for H₂O₂ in cell lysate, it is worth mentioning that the electrochemical H₂O₂ sensor developed in this study is simpler and faster, with higher sensitivity and lower cost. This provides a potential substitute for disease diagnosis and treatment evaluation based on accurate detection of H₂O₂.
