Introduction of graphene oxide-supported multilayer-quantum dots nanofilm into multiplex lateral flow immunoassay: A rapid and ultrasensitive point-of-care testing technique for multiple respiratory viruses.
面对新冠疫情,亟需一种能够灵敏、准确识别严重急性呼吸综合征冠状病毒2(SARS-CoV-2)及其他常见呼吸道病毒的侧流层析免疫分析(LFA)生物传感器。本文提出一种多重LFA方法,用于现场快速、高灵敏筛查多种呼吸道病毒,并以多层膜状荧光标记作为性能增强和信号放大工具。该膜状三维标记通过高光稳定CdSe@ZnS-COOH量子点(QDs...
