A Novel Method for the Selective Determination of Silver (I) Ion

摘要

Water-soluble CdSe quantum dots (QDs) capped by bovine serum albumin (BSA) is described as selective silver (I) ion probe based on their fluorescence (FL) quenched by silver ion at pH 5.7. The detection limit is 3×10-7 mol L-1 for silver ion. The interference was also investigated.
