Dye-tagged aptamers and their complementary sequence with thiol labels are co-assembled at the surface of AuNPs. As a proof of concept, it is demonstrated that such a multicolor fluorescent gold nanoprobe can simultaneously detect adenosine, potassium ion, and cocaine with high selectivity. This potentially generic strategy is shown to be promising for rapid screening of small molecular targets.||URI:||https://hdl.handle.net/10356/99641
