摘要：

Organic electrochemical transistors are integrated in flexible microfluidic systems. A novel label-free DNA sensor is developed based on 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.
