摘要: 以倏逝波光纤荧光生物传感器为平台,以邻苯二甲酸酯类(PAEs)污染物为靶标,优化了基于受体作用理论的生物传感分析技术,实现了PAEs雌激素结合活性的定性筛查。对7种典型邻苯二甲酸酯的雌激素结合活性测试结果为BBP>DBP>DIPP,其他4种物质几乎无雌激素结合活性,结果与文献广泛报道结论相一致,验证了所建立方法的准确性。在最优测试条件下,光纤传感界面可再生300次以上,为雌激素活性污染物的筛查提供了一种低成本、自动化方法。

Abstract: Taking the evanescent-wave optical fiber fluorescent biosensor as a platform and the phthalic acid esters(PAEs)contaminants as targets,the biosensing analytical technology based on the estrogen receptor interaction theory was optimized,and qualitative screening of estrogen binding activity of PAEs was achieved. The order of the estrogenic binding activity of seven typical PAEs were BBP > DBP > DIPP. The other 4substances had almost no estrogenic binding activity,which was consistent with the widely reported conclusions in Literatures,and confirming the accuracy of the established method. Under the optimal test conditions,the optical fiber sensing surface can be regenerated more than 300 times,providing a Low-cost,automated method for the screening of estrogenic contaminants.

Key words: evanescent-wave fiber fluorescent biosensor, estrogen receptor, phthalates, estrogenic binding activity
