Abstract

This study investigates nanowires using Dielectrophoresis (DEP) in non-aqueous suspension of Zinc Oxide (ZnO) nanoparticles dispersed in N,N-DIMENTHYLFORMAMIDE (DMF). The self assembly of nanowires in DEP impedance spectroscopy can be determined. In this work, dielectrophoretic measurements of inorganic have been used to estimate the permittivity and conductivity characteristic of the nanowires. As in aqueous such as salt solution has been dominating the transport of ZnO, which are the wire growth threshold, depend on applied voltage. While DEP assembly of nanowires depend on applied frequency, the applications of dielectrophoretic collection are measured using impedance spectroscopy.
