Preparation of PVP-Cys CuNCs and Its Application in Determination of Berberine
{{output}}
Polyvinylpyrrolidone (PVP) and cysteine (Cys) double-ligand-modified copper nanoclusters (PVP-Cys CuNCs) were synthesized by a one-pot method. The addition of Cys can protect copper nanoclusters (CuNCs) more effectively and enhance its fluorescence intensity, ... ...
