Functional covalent organic framework H2S sensors for periodontitis monitoring and antibacterial treatment

Incorporating the indicator (PB) and COF (EB-TFP), the IDA-based fluorescence-enhanced gas sensor (EB-TFP@PB) exhibited selective binding with H 2 S. EB-TFP@PB showed selective antibacterial activity against S. aureus under non-illuminated conditions.
