ABSTRACT
A new type of fluorescent gold nanoclusters (MU-Au NCs) was prepared by hydrothermal synthesis method using ammonium benzoate murexide (MU) as reducing agent and protecting agent.The synthesis method was simple and rapid.Based on the fluorescence quenching ability of spermine, a turn off type fluorescence analysis method was established for rapid and ultra sensitive detection of spermine.The linear range for detection of spermine was 0.003-300 μmol/L and the detection limit was 1 nmol/L (S/N=3).The established analytical method of spermine provided theoretical basis and reference for construction of spermine biosensor and actual sample detection.
