Abstract:
Using polythiophene derivatives as single source precursors, nitrogen (N) and sulfur (S) co-doped graphene quantum dots (NS-GQD) were prepared. Under two-photon excitation (800 nm), the NS-GQD exhibited excellent photostability and high (1)O2 generation, and therefore were developed as photodynamic therapy agents for cancer treatment.
