Abstract

Abstract In this study, for the first time, Porphyromonas gingivalis , an anaerobic bacterium, was selected to synthesize carbon dots. The achieved P. gingivalis –carbon dots (Pg‐CDs) exhibited strong fluorescence and high stability with capability for dual function as Fe 3+ sensor and intracellular imaging agent. The detection limit for Fe 3+ was as low as 1.85 µ m . On the other hand, the prepared Pg‐CDs were an excellent candidate for biosensor with high biocompatibility.
