基于表面增强拉曼散射(SERS)和电化学检测方法，提出了一种新型木素修饰的聚苯乙烯-共丙烯酸复合微球，用于2，4，6-三硝基甲苯(TNT)炸药的选择性高灵敏检测和去除。木质素的存在和Fe3O4/AuNPs的高填充层作为SERS信号的磁性收集器和金属增强剂，允许在下午1点以下检测到TNT
A new lignin modified hybrid microsphere, comprising poly(styrene-co-acrylic acid) core and magnetite (Fe3O4)/Au nanoparticle (NP) shell, was proposed here for the selective and highly sensitive detection and removal of 2,4,6-trinitrotoluene (TNT) explosives based on surface enhanced Raman scattering (SERS) and electrochemical detection methods. The presence of lignin and the highly packed layer of Fe3O4/AuNPs as a magnetic collector and metal enhancer for SERS signals allowed for the detection of TNT below 1 pM.
