摘要: Biological and medical fields have authenticated stupendous advancement in the development of biosensors and biochips. The development of highly sensitive biological sensors is need of the hour. This research work utilizes the dielectrophoretic concentrator chip with titanium (Ti) electrodes to shape the electric field, to pre-concentrate deoxyribo nucleic acid (DNA) within microfluidic channel onto nanowire region of poly-silicon nanowire field effect transistor (poly-Si NWFET). Preconcentration of biomolecules at the constriction site was demonstrated by focusing the DNA with negative dielectrophoresis (nDEP) manipulation technique. After integrating the DEP device with poly-Si NWFET, the I-V-G curve was plotted to ensure n-type behavior.
