Highly luminescent nanospheres have been demonstrated to enhance the sensitivity of lateral flow immunoassay (LFIA) due to their loading of numerous luminescent dyes. Herein, aggregation-induced emission (AIE) luminogens (AIEgens)-embedded nanospheres (AIENPs) with red-emissive AIE-active europium complexes were developed as signal amplification probes for LFIA for rapid and point-of-care detection of COVID-19 biomarkers, nasopharyngeal carcinoma biomarkers, and methamphetamine. Compared with the colloidal gold-based rapid and point-of-care detection approach, the AIENPs-based approach showed more than 10 times sensitivity to the target proteins and small molecules, highlighting its significant potential for pathogen- or cancer-related diseases early detection and screening, as well as its applicability in public safety monitoring.

There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or...
