Nitrogen and sulfur co-doped carbon dots (N,S-CDs) as a simple “on–off–on” fluorescent probe were applied for quickly detecting Cu2+ ions and GSH in living cells.
N and S co-doped carbon dots (N,S-CDs) synthesized from biomass can be used as multicolor probes for cell imaging. The N,S-CDs can selectively and sensitively detect Cr(vi) in real lake water, human serum and living cells.
Fluorescent carbon dots derived from natural biomass have received widespread attention in recent years due to their superior optical and chemical properties. In this work, we proposed a method to...
