莠去津免疫传感器的功能膜的制备及FTIR-RAS光谱表征

Construction of the Functionalized Film of Immobilized Atrazine Molecular on the Surface of Gold Substrate and Its Characterization by FTIR-RAS

基于FTIR-RAS检测技术原理,文章计划制备一种新型痕量杀虫剂传感器。在金基板表面上,利用含硫有机物易自组装单分子层的特点,制备了杀虫剂莠去津修饰的功能表面。首先合成杀虫剂莠去津功能化的硫醇衍生物,然后将其自组装到金基板表面上;功能化的金基板表面通过FTIR-RAS进行了表征,对功能表面的形成特性以及与抗体的相互作用情况进行了初步研究。

In an attempt to implement a novel type of immuno sensor based on IR spectroscopy, the authors have immobilized the herbieide atrazine on the surface of gold substrates. First, the authors synthesized a disulphide derivative of atrazine, then immobilized the herbicide atrazine on the surface of gold substrates by spontaneous ehemisorption. The organic thin films were eharaeterised by Fourier transform infrared reflection-absorption spectroscopy. A preliminary biological recognition experiment with an anti-ATZ antibody is promising.
