One step synthesis of boron-doped carbon nitride derived from 4-pyridylboronic acid as biosensing platforms for assessment of food safety

The rational design of heteroatom-doped C 3 N 4 offers a great opportunity to optimize C 3 N 4 performance. In this communication, we propose a facile method to fabricate layered-stacked B-doped C 3 N 4 (BCN-800) ultrathin nanosheets via a one-step calcination route. The distinctive layered-stacked...

Description
Summary:The rational design of heteroatom-doped C 3 N 4 offers a great opportunity to optimize C 3 N 4 performance. In this communication, we propose a facile method to fabricate layered-stacked B-doped C 3 N 4 (BCN-800) ultrathin nanosheets via a one-step calcination route. The distinctive layered-stacked structure and the presence of B atoms provide an active attachment point for antibodies and antigens. In addition, the presence of C and N might aid stability and increase conductivity. When used for vomitoxin detection, the BCN-800-based electrochemical biosensor exhibits high sensitivity with a detection limit of 0.32 pg mL −1 and superior selectivity to other interfering agents. Boron-doped carbon nitride nanosheets derived from a 4-pyridylboronic acid precursor are synthesized as biosensing platforms for assessment of food safety. The BCN-800-based electrochemical biosensor exhibits high sensitivity with a detection limit of 0.32 pg mL −1 .
