【摘要】 在水溶液中合成了CdS纳米粒子,利用超声辐射下原位聚合方法合成了聚4-戊烯酸(PPA)包裹的CdS/PPA复合纳米溶胶。作为荧光探针,建立了同步荧光光度法测定牛血清蛋白的工作曲线ΔF=117.50+29.55c(1×10-6g/mL),线性范围为0.50×10-6~30×10-6g/mL,检出限为0.12×10-6g/mL。对合成样品进行了测定,结果令人满意。更多还原

【Abstract】 CdS nanoparticles were synthesized in water solution,the surface of CdS nanoparticles was modified with poly-4-pentenoic acid under ultrasonic irradiation.With CdS/PPA nanoparticle solution as fluorescence probe combined with synchronous fluorescence spectrometry,a method for determination of BSA in water solution was developed.The working curve for determination of BSA is ΔF=117.50+29.55c(1×10-6 g/mL),the linear range is 0.5×10-6~30×10-6 g/mL,the limit of detection is 0.12×10-6 g/mL.In addition,the present method was applied to quantifying BSA in synthetic samples.更多还原
