Electrochemiluminescence devices for point-of-care testing

Point-of-care testing (POCT) is also known as near-patient or on-site testing. Because of its speediness, high efficiency, low cost, and excellent convenience, POCT has been widely used in clinical diagnosis, infectious disease surveillance, drug screening, and food quality monitoring. Electrochemiluminescence (ECL) is a powerful transduction technique in biosensing and immunodiagnostics, thus attracting more and more research attention in POCT applications. In this article, we present an overview of various ECL-POCT devices that have been developed so far. The article will begin with a short introduction of different types of ECL-POCT devices. Then we shall discuss the categories, detection strategies, and application scenarios of current ECL-POCT devices. The article finally ends up with a short conclusion and perspectives. We hope this article is helpful for understanding, constructing, and designing ECL devices for POCT. This review summarizes the research progress of ECL-based POCT devices, including categories, detection strategies and application scenarios, which we believe will help construct and design ECL devices for POCT.
