摘要
利用牛血清白蛋白(BSA)模板荧光铜纳米簇为荧光探针,发展了一种快速、非标记型的荧光生物传感新方法用于四环素的灵敏检测.结果表明,四环素的线性检测范围为5.0×10^(-8)~4.0×10^(-5)mol/L,检出限为5.0×10^(-9)mol/L(RSN=3).该方法已成功地应用于牛奶样品中四环素含量的测定,相对误差不大于3.3%,加标回收率在96.0%~102.8%之间.该研究为四环素的灵敏检测提供了一种快速、方便的新方法.
A rapid and label-free fluorescent sensing method has been established for sensitive detection of tetracycline(TC)by using bovine serum albumin(BSA)templated CuNCs as fluorescence probes.The strategy permitted sensitive detection of tetracycline in a linear range from 5.0×10-8 to 4.0×10-5 mol/L and with a detection limit of 5.0×10-9 mol/L.The sensor was successfully applied to determinate the tetracycline content in milk samples.It could provide a rapid and convenient fluorescent platform for tetracycline detection.
