A simulation study on the performance of various label-free electronic biosensors
Authors
Abstract
The efficient detection of charged biomolecules by biosensor with appropriate semiconducting nanomaterials and with optimum device geometry has caught tremendous research interest in the present decade. Here, the performance of various label-free electronic biosensors to detect bio-molecules is investigated by simulation technique. Silicon nanowire sensor, nanosphere sensor and double gate field effect transistor (DGFET) sensor with different device parameters are reported here and their performances are compared. For the three types of sensors, radius of the nanowire, radius of the nanosphere and the silicon body thickness for the DGFET are varied to compare their selectivity, sensitivity, settling time etc. The result of adjustment of the flow of the fluid is also investigated by simulation.
