We have developed a simple solid-state synthesis procedure to functionalize fluorescent carbon quantum dots(CQDs),using ammonium citrate as a carbon source and appropriate molecules as recognition ligands.Mannose and folic acid were used to modify CQDs to selectively label Escherichia coli(E.coli) and tumor cells,respectively.
