摘要:以 β-环糊精(β-CD)和氯金酸为原料,制备了 β-环糊精包被的金纳米粒子(β-CD@AuNPs),通过 TEM、
FTIR、UV-Vis 和荧光光谱表征了 β-CD@AuNPs 的结构及光学特征。基于 β-CD@AuNPs 对罗丹明 B(RB)的
荧光猝灭、性激素(孕酮、雌二醇、睾酮)对 β-CD@AuNPs-RB 体系荧光的恢复现象,构建了高选择性、高灵
敏度的 β-CD@AuNPs-RB 荧光探针用于检测性激素。结果表明,0~7.5 μg/g 的孕酮与 β-CD@AuNPs-RB 的荧光

恢复率呈良好的线性关系,线性相关系数(R )为 0.992,检测限为 0.047 μg/g。另将此 β-CD@AuNPs-RB 用于

检测雌二醇和睾酮,β-CD@AuNPs-RB 的荧光恢复率与 0~15 μg/g 的性激素呈良好的线性关系(R >0.99),检测
限分别为 0.15 和 0.37 μg/g。将 β-CD@AuNPs-RB 荧光探针用于爽肤水中性激素的测定,性激素回收率为
95.00%~104.67%,相对标准偏差≤4.7%。

Abstract: Gold nanoparticles coated with β-CD(β-CD@AuNPs) were synthesized from β-cyclodextrin
(β-CD) and chlorauric acid, and characterized by TEM, FTIR, UV-Vis and fluorescence spectra for
structural and optical property analysis. A fluorescence probe (β-CD@AuNPs-RB) with high selectivity and
sensitivity was then constructed for sex hormone detection based on the quenching of Rhodamine B (RB)
fluorescence by β-CD@AuNPs and the fluorescence recovery of β-CD@AuNPs-RB with sex hormone
(progesterone, estradiol, testosterone). The results showed that the correlation between fluorescence
recovery rate of β-CD@AuNPs-RB and progesterone in the range of 0~7.5 μg/g was linear with the linear
2
correlation coefficient (R ) of 0.992 and the detection limit to 0.047 μg/g. Meanwhile, it was also found that
there was a good linear correlation between fluorescence recovery rate of β-CD@AuNPs-RB and estradiol
2
or testosterone from 0 to 15 μg/g with R >0.99 and the detection limit of 0.15 and 0.37 μg/g,
respectively. Furthermore, when the β-CD@AuNPs-RB fluorescence probe was used for the determination
of sex hormone content in skin care toner, the recovery rate of sex hormone was 95.00%~104.67% and
relative standard deviation was≤4.7%.
