Organic and hybrid electronics in optical sensing

Promising applications of organic electronics (OE), which include (bio)chemical sensing and biomedical diagnostics have been on the rise. Resulting devices are compact, low-cost, and efficient. They can be fabricated on glass or flexible plastics. Wearable designs are possible. A review will be presented on the utilization of (microcavity) OLEDs, tunable (wide and narrow band) organic and fast-responding hybrid perovskite-based photodetectors, and their combinations in all-organic, photoluminescence (PL)-based sensing platforms for efficient, simultaneous detection of multiple analytes. Analyte detection is based on monitoring dose-dependent changes in the PL intensity or decay time (a preferred approach) of analyte-sensitive dyes. Related applications and the integration of such OE tools with microfluidic channels for compact lab-on-a-chip designs, addressing the need for sensor miniaturization, will also be discussed.
