A cell-based electrical detection of drugs or toxicant effects is promising technology because of its simplicity and convenience with short detection time. In this study, we fabricated a neural cell chip to investigate dose-dependent toxic effects of bisphenol-A on PC12 Cells. A non-toxic plastic chamber was fixed on a gold electrode deposited silicon bottom, which was used as working electrode in three electrode systems. Electrochemical behavior of neural cancer cells were measured using cyclic voltammetry (CV) after 24h of incubation. The cathodic peak (Ipc) from CV was used as a parameter representing the effects of bisphenol-A on cells viability. The results show that bisphenol-A have stimulatory effects on neuronal cells at lower dose than 150nM but have cytotoxic effect at higher dose than 150nM. These dual effects of bisphenol-A on PC12 cells were confirmed by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and western blot analysis with maintaining similar culture condition. This developed electrochemical analysis system is a promising tool for drug screening and environmental toxicant detection.
