Fluorescence on-off system silver hybrid-polymer dot for bacteria detection and killing |
초록 |
We studied an effective nanomaterial for the detection of bacteria and the measurement of antimicrobial activity using fluorescent polymer dots and silver nanoparticles. We developed a PVP@Ag:PD system that takes highly fluorescent form using catechol chemistry to avoid fluorescent reduction of PD-Ag due to FRET quenching. Positively charged PVP@Ag:PD promotes and aggregates with the bacteria surface which mostly negative charge, influencing the fluorescence of the system due to intermolecular interaction. Even at low concentrations, PVP@Ag:PD showed prominent and sensitive bacterial killing efficiency. Using this feature, we developed a system for detecting and killing bacteria that combines biosensors with antimicrobial activity. Thus, this system provides a possibility for future bacteria sensing and extermination. This was supported by Korea National University of Transportation in 2020. |
