摘要：

Carbon dots are promising scaffolds for multifunctional therapeutic systems because of their fluorescence property, good biocompatibility, and low toxicity. In this work, we prepared nitrogen-doped carbon dots through an aqueous phase strategy using folic acid as precursor. The carbon dots possess many attractive features including uniform dispersion with size about 9 nm, bright photoluminescence, high photoluminescence quantum yield of 23%, and low toxicity, making them excellent imaging probes for biomedical applications.
