Researchers from the Max Planck Institute for Biochemistry have taken a step toward more specific biological-electronic communications with a device that allows a field effect transistor on a silicon chip to sense the electric potential created by a nerve cell, and the nerve cell to sense a voltage pulse in the chip.
The researchers cultured the cells on an oxidized silicon chip coated with collagen. The cell’s ion current flowed through the cell membrane and then continued along the narrow gap between the cell and the chip. This gap current gave rise to a voltage drop that changed electron flow in the silicon on the other side of a thin insulating oxide layer.
