【摘要】 研究漆黄素-纳米银体系的荧光光谱特性,建立灵敏的测定漆黄素的新方法。利用荧光分析方法,以纳米银-十六烷基三甲基溴化铵(CTAB)为荧光增强试剂,研究其与漆黄素相互作用的光谱性能及各种因素的影响。结果表明:在最佳实验条件下,体系的荧光增强程度与漆黄素浓度在5.0×10-8-1.0×10-5mol/L范围内成正比,检出限为4.1×10-9mol/L。更多还原

【Abstract】 The fluorescence spectral characteristics of fisetin-Silver nanoparticles(AgNPs) were studied.A sensitive method for the determination of fisetin was proposed.The enhanced fluorescence was obtained when AgNPs-CTAB complex as fluorescence enhancement reagents bound to fisetin.The enhancement of fluorescence intensity is in proportion to the concentration of fisetin is in the range 5.0×10-8-1.0×10-5 mol/L,the detection limit for the fisetin(S/N = 3) was 4.1×10-9 mol/L。更多还原
