Miniaturized interdigited based Field Effect Device with modified sensing parameters

This work focuses on improving the sensitivity of multi walled carbon nano tube (MWCNT) The strategy is toshrink down the size of interdigitated electrodes and the gaps between them. In this structure we use a back gate to modify the I-V characteristic of the device. The results of using the device as a glucose sensor shows resistance is proportional to the concentration of the gluscose solution in contact with immobilized enzyme on surface of MWCNT. The ability to use more interdigitated electrodes to improve the sensitivity and good conductivities are key features of this work.
