报告摘要：

Cellular and subcellular-level interfaces between electrical sensors and biological systems are crucial for both fundamental biophysical studies and medical monitoring and intervention. In this presentation, I will talk about our recent progress of developing novel nanoscale field-effect transistor (FET) based functional devices to record action potentials from inside living electroactive cells. Compared to other available recording methods, these FET based intracellular nanodevices allow for unprecedented miniaturization and scaling-up of probes, thus providing a potential nanotool for large-scale, high spatio-temporal resolution mapping of neural activities.
