Abstract
CFU/mL, and the detection limit is 9 CFU/mL. In addition, the proposed biosensor has achieved satisfactory results in the detection of actual water samples and diluted honey samples, which confirm the practicability of the biosensor and its application potential in environmental monitoring and food safety.
