The Field Effect of Concentration DNA on Conductance of Silicon Nanowire

Abstract:

Currently, the potential use of Semiconductor nanowires as parts of future devices has triggered an increased interest in biosensor research. The COMSOL Multiphysics is simulation used that can improve the sensitivity of Bioelectronics to extend their stability and utility. In this paper, we are investigating the effect of DNA concentration of the electrolyte effect biosensor on the conductance of the nanowire through finite element calculations. First, the distribution of the electrostatic has potential in the nanowire due to the DNA concentration. In conclusion of this paper represented DNA that conductance nanowire is affected from surface modification after DNA including on the model.
