Abstract
Size-tunable graphene oxides (GO) were synthesized as a horseradish peroxidase (HRP) mimic for colorimetric detection of organophosphorus pesticides (OPs) at nanomolar levels via a cascade reaction. A GO-based colorimetric method showed high sensitivity and stability toward OPs, which hold great potential in public health applications.
