摘要：
In this communication, for the first time, the facile production of cobalt disulfide nanowires (CoS2 NWs) is achieved in solution using a two-step hydrothermal method and the formation mechanism of CoS2 NWs is based on the anion-exchange reaction involving the pseudo Kirkendall effect. As a proof-of-concept application, CoS2 NWs are applied as an effective fluorescent sensing platform for the detection of nucleic acid and this nanosensor exhibits extraordinarily high sensitivity with a detection limit as low as 10 pM and good selectivity. Most importantly, the successful use of this sensing platform in the fetal bovine serum system is also demonstrated.
