Abstract

Planar patch-clamp chips have been developed in varies approaches to simplify ion-channel signal detection. Integration with microfluidics has mainly focused on delivery of prepared solutions to the chip. This work presents the integration of planar patch-clamp chip with microfluidic concentration generator for rapid solution exchange. Different concentrations of fluid could be rapidly delivered and exchanged by adjusting relative flow rate of each inlet, and fully mixed through a micromixer. Endogenous chloride channels in human embryonic kidney 293T cells were successfully examined in various osmolarities generated by the concentration generator. This practical approach demonstrates the potential of integrated microfluidic patch-clamp system for high throughput ion channel screening of drugs.
