文摘

The carbon dots were synthesized by a facile one-step hydrothermal approach. The carbon dots exhibit the excitation-dependent PL behaviors with high quantum yield. The carbon dots can distinguish FA-receptor-positive cancer cells from normal cells. The carbon dots with positive charges can link to plasmid DNA and efficiently transfect the therapeutic plasmid into cells.
