Abstract

Traditional peroxidase-like nanozyme-based sensors suffer from self-decomposition and high toxicity of H 2 O 2, as well as the interference of color from nanozymes themselves and testing samples. In this work, we adopt nanozymes (two-dimension (2D) MnO 2 sheets, manganese dioxide nanosheets (MnNS)) ...
