The present study compares two single-gated field effect transistors (FETs) for cholesterol detection. One is traditional graphene-FET and the other is junctionless carbon nanotube (CNT) FET. Both the FETs have been fabricated using the electrochemical deposition (ECD) technique. Cholesterol response has been recorded in a glass pot containing phosphate buffer saline (PBS) using digital multimeter. Response study implies that junctionless CNTFET shows improved sensitivity of 87 μA/mM, higher than the sensitivity of traditional graphene-FET (18 μA/mM). Limit of detection (LoD) has been found to be 0.25mM for JLCNTFET and 1.4mM for graphene FET. Furthermore, the fabrication of junctionless CNTFET is simpler and can be easily done using minimal instrumentation. |
