Organic electrochemical transistors are integrated in flexible microfluidic systems. A novel label‐free DNA sensor is developed based on the devices with single‐stranded DNA probes immobilized on gate electrodes. These devices successfully detect complementary DNA targets at low concentrations using a pulse‐enhanced hybridization technique in microfluidic channels. Organic electrochemical transistors are excellent candidates for flexible, highly sensitive, and low‐cost biosensors.
