Traditional and junctionless field effect transistor for cholesterol detection

The present study compares the traditional field effect transistors with newly developed junctionless carbon nanotube field effect transistor (JLCNTFET) for cholesterol detection. JLCNTFET has been fabricated using electrochemical deposition (ECD) technique on indium tin oxide (ITO) coated glass. A digital multimeter (DMM) has been used for measurement of cholesterol response in a glass pot containing phosphate buffer saline (PBS). The response study implies that JLCNTFET shows improved sensitivity than other for cholesterol detection. From this work, it has been observed that fabrication of junctionless CNTFET is simpler and requires minimal instrument. Therefore, effort has been made to utilize this nano-structured JLCNTFET for estimation of various clinical disorders.
