<i>In situ</i> synthesis of fluorescent copper nanoclusters for rapid detection of ascorbic acid in biological samples

Abstract

Schematic presentation of the <italic>in situ</italic> synthesis of fluorescent copper nanoclusters for rapid determination of ascorbic acid is provided. After addition of ascorbic acid, copper(<sc>ii</sc>) is reduced to copper(0) and then clustered on dsDNA, thus producing red-emission CuNCs.
