dc.description.abstractCarbendazim (CBZ) was widest used in agriculture for its high efficiency in controlling of fungal diseases. However, CBZ can pose serious contamination to agricultural products and water resource for its long half-lives and high toxicity. Therefore, precise detection of CBZ residues is very important for human health and envi-ronmental safety concerns. Nevertheless, the inherent electrode fouling effect caused by CBZ products hinders the precise and practical determination of CBZ. Herein, a novel highly antifouling heterostructure based on carboxylated multiwalled carbon nanotubes (MWCNT-COOH) functionalized black phosphorus (BP) have been successfully developed via a facile sonication assisted self-assembly method. The electrochemical interface of BP/ MWCNT-COOH modified glassy carbon electrode shows excellent catalytic activity to CBZ oxidation and good electrode antifouling effect, ensuring repeatable and precise detection of CBZ. In addition, the sensor shows a wide linearity from 9.0 nM to 1000 nM with a detection limit of 4.0 nM which superior to most of previous work. Moreover, the BP-based non-enzymatic sensor shows good selectivity and satisfactory recoveries for real sample analysis, confirming its highly practical application. The antifouling mechanism to CBZ for the sensor and the interaction mechanism between MWCNTs-COOH and BP were also illustrated by theory calculations.
