Olfactory and taste cell sensor and its applications in biomedicine

A review of an olfactory and taste cell sensor is presented in this article. Olfactory and taste cell sensor is one kind of cell-based on biosensors which are based on the electronic nose and electronic tongue research, trying to culture olfactory and taste living cell on the surface of chips. This is a really mimicking bioelectronic nose and tongue technology, which can detect odors and taste by using chips such as light-addressable potentiometric sensor to record action potential representing the odorants and taste in cell membrane. Now, several kinds of cells from olfactory bulb and taste bud on chip have been cultured, while the experiments and analysis about the detection of olfactory and taste and its action potential under the stimulus of different odors and taste also are in progress.
