Aggregation-Induced Emission-Fluorescent-Microsphere-Based Lateral Flow Immunoassay for Highly Sensitive Detection of Capsaicinoids

Capsaicinoids (CPCs) are regarded as a typical marker of waste oil, which has emerged as a serious food safety issue in developing countries, necessitating the development of rapid, sensitive, and specific detection methods. In this study, a novel hapten was synthesized to generate a high-affinity monoclonal antibody (mAb) targeting CPCs. Subsequently, aggregation-induced emission fluorescent microspheres (AIEFMs), known for their supe- rior fluorescence intensity, were utilized as an enhanced...
