Summary: Electrowetting-on-dielectric (EWOD) is an active-type technology for small-scale liquid handling that offers unique advantages such as no requirement of mechanical components, low power consumption, and rapid response time. However, conventional EWOD devices often require complex fabrication processes and face integration challenges. Optoelectrowetting (OEW), a light-driven mechanism, has emerged as an alternative approach that allows for dynamic control of electrowetting without complex control circuitry. OEW has been explored for potential applications in biology, biochemistry, and as portable smartphone-integrated environmental sensors.

Summary: Organic electronics (OE) technology has matured in displays and is advancing in solid-state lighting applications. It also shows great potential in (bio)chemical sensing, imaging, in vitro cell monitoring, and other biomedical diagnostics. OE devices, such as organic LEDs, organic and hybrid perovskite-based photodetectors, and organic thin-film transistors, are utilized in these applications. The integration of compact and sensitive OE devices with microfluidic channels and lab-on-a-chip (LOC) structures is very promising.

Summary: This study presents a method to fabricate independently functioning microneedle (MN) electrodes with narrow intervals for high precision electrochemical sensing. The optimized mixture of photocurable polymer and single-wall carbon nanotubes was used to mold single composite MNs, which were then attached to pre-patterned electrodes. Plasma etching and electropolymerization were performed to enhance the electrochemical activity, and Prussian blue and glucose oxidase were electrodeposited on the MNs for glucose detection. The MN electrodes showed good sensitivity and linearity, and the feasibility of glucose detection was demonstrated in an in vivo mouse study.
