Set them free: Brightly fluorescent indicators that are loaded into mesoporous silica nanoparticle carriers, capped with bulky antibodies, are released into the lateral flow of a test strip upon analyte arrival. Integration of the system into a rapid, simple flow test with fluorescence readout is applied for the selective and sensitive determination of the presence of triacetone triperoxide (TATP)
放开它们:装载到中孔二氧化硅纳米颗粒载体中的明亮的荧光指示剂,被大分子抗体覆盖,在分析物到达时释放到测试条的侧向流中。将该系统集成到具有荧光读数的快速,简单的流量测试中,可用于选择性和灵敏地确定三丙酮三氧化二氧(TATP)作为原型小分子分析物的存在(见图)。
