Rational Design of Electrochemiluminescent Devices

ConspectusElectrochemiluminescence (ECL) is a light-emitting process which combines the intriguing merits of both electrochemical and chemiluminescent methods. It an extensively used method especially in clinical analysis biological research due to its high sensitivity, wide dynamic range, good reliability. ECL devices are critical for development applications ECL. Much effort has been expended improve portability, affordability, throughput new devices, allow adapt broad usage scenarios.In this Account, we summarize our efforts on recent including electrodes, based wireless power transfer (WPT) technique, novel bipolar electrochemistry. As essential components electrodes play important role detection. We have significantly improved sensitivity luminol detection H2O2 by using stainless steel electrode. By semiconductor materials (e.g., silicon BiVO4), exploited photoinduced generate intense emission at much lower potentials upon illumination. For convenience, disposability, cheap WPT designed. A small diode employed rectify alternating current into direct dramatically enhance intensity, enabling sensitive smart phone as detector. Finally, developed several electrochemistry view convenience multiplex sensing electrode (BPE). On basis feature BPE, movable BPEs BPE swimmers magnetic rotating BPE) deep exploration motional properties systems. To make full use solution, dispersed numerous micro-/nano-BPEs solution produce 3D entire instead 2D conventional devices. In addition, interference noise from driving was minimized introducing with passivation layer eliminate need fabrication arrays decrease applied voltage, develop new-type device consisting single-electrode system (SEES) resistance-induced potential difference. The SEES fabricated easily attaching multiperforated plate single film enables simultaneous many samples analytes only screen-printed electrode) arrays. great multiple-biomarker detection, drug screening, studies. Looking forward, believe that more related methods will be range applications, such vitro diagnosis, point-of-care testing, high-throughput analysis, study, mechanism investigation.
