Tóm tắt

This study introduces the synthesis of amino acid-based nitrogen-doped carbon dots (N-L-Ser-CDs) from L-serine (L-Ser) and urea through a straightforward and economical one-step solid-phase pyrolysis process. The incorporation of nitrogen into the carbon dots resulted in a remarkable 27.6-fold increase in fluorescence intensity, featuring a peak emission at 405 nm when excited at 330 nm and a significant fluorescence quantum yield of 22.5%. These N-L-Ser-CDs displayed a specific binding affinity for Cu
