This Minireview focuses on recent advances in the applications of microelectrodes to detect and monitor targeted analytes in bioelectrochemical processes. Notably, these processes are electrochemically driven reactions that involve the detection of targets from the biological realm. Wide-ranging applications of electrochemical sensors have been reported in the last few decades in various research fields, owing to favorable attributes such as high selectivity and sensitivity, rapid analysis, simplicity, easy fabrication, and cost effectiveness. Accordingly, in this Minireview, we explore recent advances in bioelectrochemistry based on small detection probes or structures modified for a variety of analytes, exploiting multi-approach advantages of enhanced electrochemical detection surface or targeted analyte pursuit. The target analytes included in this Minireview are neurotransmitters and disease biomarkers detected using enzymatic and non-enzymatic electrode modifications.
