In this study, a simple, one-step organic molecule 3-aminopropyltriethoxysilane (APTES) functionalized surface plasmon resonance (SPR) sensor was developed. APTES as an organic ligand immobilized on the SPR sensor chip was used to form the Meisenheimer complex with 2,4,6-trinitrotoluene (TNT). The results of using the APTES-based SPR sensor chip show a highly selective and sensitive (ppb level: parts per billion) detection of TNT explosive. The sensor is expected to have potential for application in the fast screening of the TNT explosive.

一种简单、快速且低成本的基于 3-氨基丙基三乙氧基硅烷 (APTES) 的表面等离子体共振传感器,用于 TNT 爆炸物检测
在这项研究中,开发了一种简单的一步有机分子 3-氨基丙基三乙氧基硅烷 (APTES) 功能化表面等离子体共振 (SPR) 传感器。APTES 作为固定在 SPR 传感器芯片上的有机配体用于与 2,4,6-三硝基甲苯 (TNT) 形成迈森海默复合物。使用基于 APTES 的 SPR 传感器芯片的结果显示了对 TNT 爆炸物的高度选择性和灵敏性(ppb 级:十亿分之一)检测。该传感器有望应用于 TNT 炸药的快速筛选。
