摘要
Establishing a reliable electrophysiological recording platform is crucial for cardiology and neuroscience research.Noninvasive and label-free planar multitransistors and multielectrode arrays are conducive to perform the large-scale cellular electrical activity recordings,but the signal attenua-tion limits these extracellular devices to record subthreshold activities.In recent decade,in-cell nanoelectronics have been rapidly developed to open the door to intracellular electrophysi-ology.With the unique three-dimensional nanotopography and advanced penetration strategies,high-throughput and high-fidelity action potential like signal recordings is expected to be realized.This review summarizes in-cell nanoelectronics from versatile nano-biointerfaces,penetration strategies,active/pas-sive nanodevices,systematically analyses the applications in electrogenic cells and especially evaluates the influence of nanodevices on the high-quality intracellular electrophysiological signals.Further,the opportunities,challenges and broad prospects of in-cell nanoelectronics are prospected,expecting to promote the development of in-cell electrophysiological platforms to meet the demand of theoretical investigation and clinical application.
