A Host-Guest-Regulated Photocurrent Polarity Switching with a "Binary" Strategy for False-Positive-Free Microbial Detection of Staphylococcus aureus
{{output}}
Herein, we report a supramolecular photoelectrochemical (PEC) biosensor based on a signal-polarity-inversion strategy, integrated with bacterial imprinting technology, for the ultrasensitive and selective detection of Staphylococcus aureus (S. aureus). The bio... ...
