A method for noncompetitive detection of a small analyte using nanopeptamers, and devices useful for performing the methods. Nanopeptamers include a self-associating oligomeric protein that is attached to peptides that bind to an immune complex between the target analyte and a capture antibody. The noncompetitive methods allow for the direct detection of small analytes with increased sensitivity over competitive methods directed to the same target analyte, and provide a positive readout which is useful for rapid tests and on-site detection of small analytes such as such as pesticides, persistent organic pollutants, explosives, toxins, medicinal and abused drugs, and hormones.
一种利用纳米肽对小型分析物进行非竞争性检测的方法,以及用于执行该方法的装置。纳米肽包括一种自结合寡聚蛋白,它附着在肽上,肽与目标分析物和捕获抗体之间的免疫复合物结合。与针对相同目标分析物的竞争性方法相比,这种非竞争性方法可直接检测小型分析物,提高灵敏度,并提供阳性读数,有助于快速测试和现场检测小型分析物,如杀虫剂、持久性有机污染物、爆炸物、毒素、药物和滥用药物以及激素。
