Abstract

See full text

The present application relates to semiconductor devices, in particular to a device for monitoring a cell signal such as an electrical signal produced by living cells in response to external stimulation, optionally in real time, comprising (a) at least one discrete area comprising a high electron mobility transistor (HEMT); and (b) non-excitable cells attached to said HEMT (HEMT element) for example, fibroblasts, HEK, CHO cell lines, keratinocytes, etc. Preferably, the HEMT is an AlGaN/GaN FET. Accordingly, the device can be applied in uses and methods for monitoring a cell signal such as an electrical signal produced by living cells in response to external stimulation, optionally in real time. Likewise, the device can be applied for screening compounds that reverse, protect from and/or shield cells from external stimuli which cause damage to cells. Also, kits comprising the device are disclosed.
