Local Redox‐Cycling‐Based Electrochemical Chip Device with Deep Microwells for Evaluation of Embryoid Bodies

Abstract

Monitoring cellular activity: A local redox-cycling-based electrochemical chip device (see picture) has been used to entrap three-dimensional culture cells and evaluate their activity. Deep microwells were incorporated into the chip device for the trapping of embryoid bodies. This chip device is useful for the evaluation of 3D organ tissues.
