基于半胱胺（CA）修饰的纳米金（AuNPs）构建了一种简单、快速的克伦特罗（CLB）比色传感器，并通过透射电子显微镜（TEM）、动态光散射（DLS）、紫外-可见光谱（UV-vis）对其进行了表征。随着克伦特罗浓度的增加，溶液颜色从红色到蓝灰色，这是由于AuNPs的聚集。克伦特罗的检测限为50 nM。与食品中的其他干扰物相比，CA-AuNPs检测系统对克伦特罗的选择性较好。该传感器已成功应用于真实的血液样品中克伦特罗的检测。
Demonstrated was a simple visual and rapid colorimetric sensor for detection of clenbuterol (CLB) based on gold nanoparticles (AuNPs) modified with cysteamine (CA) and characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS), UV-vis. The solution color from red to blue gray with increasing clenbuterol concentration resulted from the aggregation of AuNPs. The detection limit of clenbuterol is 50 nM by naked eyes. The selectivity of CA-AuNPs detection system for clenbuterol is excellent compared with other interferents in food. This sensor has been successfully applied to detect clenbuterol in real blood sample.
