Microfluidic Design of Neuron-MOSFET based on ISFET

A. Jain[1], and A. Garg[2]
[1]BITS Pilani, Goa, India
[2]Bhartiya Vidyapeeth College, New Delhi, India

In this paper we suggest a device which combines the operation of a neuron-MOS and an ISFET. An ISFET is an ion-sensitive field effect transistor used to measure ion concentrations in a solution; when the ion concentration changes, the current through the transistor changes accordingly. ...
