We report a large-scale integration (LSI) based amperometric chip device containing 400 sensors with a pitch of 250 μm and its applications for biological analysis of dopamine release from three-dimensional (3D) cultured cells using rat pheochromocytoma (PC12) cells as a neural cell model. The 3D cultured PC12 cells (PC12 spheroids) were stimulated with a high K+ solution to induce dopamine release. We showed clearly drug effects of dopaminergic drugs L-3,4-dihydroxyphenylalanine, (L-DOPA) and reserpine on dopamine release from PC12 spheroids. Our results indicate that the device is a useful tool for evaluating the effects of dopaminergic drugs.
