Abstract: Gold nanoclusters protected by bovine serum albumin is used as fluorescent probe,pazufloxacin mesylate (PZFX) is detected with high sensitivity and high selectivity through PZFX's quenching against fluorescent.The detection limit reaches 2.9×10-8 g·mL-1.This method is also used to detect urine samples.The results indicate that this method has good application prospect with characters of simple,efficient,high sensitivity and strong practicability.
