We propose a novel cell stimulation device for the analysis of cell responses to chemical stimuli. In order to deliver chemical substances to target single cells, we developed a microfluidic device having microchannels and apertures in the side wall to subject stimuli to laterally trapped cells. The channels were designed to allow simple flow control with single syringe pump. We demonstrated single cell trapping and culturing of pancreatic β cell with the device. To test its feasibility in cell stimulation assay, intracellular response of the cell to glucose stimulation was demonstrated.
