Printed electrolyte-gated transistors (EGTs) are an emerging biosensor platform that leverage the facile fabrication engendered by printed electronics with the low voltage operation enabled by ion gel dielectrics. The resulting label-free, nonoptical sensors have high gain and provide sensing operations that can be challenging for conventional chemical field effect transistor architectures. After providing an overview of EGT device fabrication and operation, we highlight opportunities for microfluidic enhancement of EGT sensor performance via multiplexing, sample preconcentration, and improved transport to the sensor surface.

印刷电解质门控晶体管生物传感器中的微流体机会。


印刷电解质门控晶体管 (EGT) 是一种新兴的生物传感器平台，它利用印刷电子器件带来的简便制造以及离子凝胶电介质实现的低电压操作。由此产生的无标签、非光学传感器具有高增益，并提供对传统化学场效应晶体管架构来说具有挑战性的传感操作。在概述了 EGT 设备的制造和操作之后，我们重点介绍了通过多路复用、样品预浓缩和改进到传感器表面的传输来微流体增强 EGT 传感器性能的机会。
