제목 High-Performance Acetylcholine Sensors Based on a Field-Effect Transistor Platform Functionalized with Synthetic Receptors
초록 Biosensors based on field-effect transistor platforms allow continuous monitoring of biologically active species with high sensitivity due to the amplification capability of detected signals. To date, a large number of sensors for biogenic substances have utilized high-cost enzyme immobilization methods. Here, highly sensitive organic field-effect transistor (OFET)-based sensors functionalized with synthetic receptors are reported that can selectively detect acetylcholine (ACh+), a critical ion related to the delivery of neural stimulation. This work describes a low-cost, simple, and viable methodology for the fabrication of highly sensitive and selective OFET-based sensors for biogenic substances, and opens up the possibilities of replacing current enzyme-based biosensors.
