| Abstract | Although vast research has been performed on biosensors, the materialization of low-cost pointof- care (POC) biosensors exhibiting portability, userfriendliness, and highly reliable analytical performance has not yet been achieved. The utilization of electronic/optoelectronic components and devices as signal transducers is being studied as a promising approach for the development of ideal POC biosensors, owing to their remarkable advantages including robust optoelectronic properties, cost-effectiveness, lowbulkiness, and flexibility in applications. This review summarizes recent notable innovations in the development of POC biosensors, in terms of transducers. Specifically, the application of optoelectronic components (e.g., diode-lighting components and semiconductor imaging sensors) and electronic devices (e.g., flatbed scanner, bio/physical sensor, and smartphone) in biosensors is described. |
