CHARACTERISTIC ANALYZING APPARATUS AND METHOD UTILIZING DIELECTRIC MIGRATION OF GRANULAR SUBSTANCE BY ANGULARLY MODULATED WAVE

摘要

(Problems);The present invention provides a method for analyzing characteristics of a particulate and an apparatus for the same, and it excels in easily and briefly optimizing an applied AC voltage frequency for the characteristics analysis on particulate characteristics or for the manipulation such as transfer, fractionation and concentration of the particle with utilizing the dielectrophoretic force.;(Means for solving problems);The present invention provides a method for analyzing characteristics of a particulate, comprising: selecting at least one particulate in a fluid; positioning said selected particulate in the vicinity of a pair of electrodes; applying a programmed voltage signal for generating a spatially inhomogeneous electric field between said pair of electrodes; detecting the movement of the particulate while applying said programmed voltage signal to create a time-series data corresponding to said movement of the particulate; and analyzing the characteristics of said particulate based on said time-series data.
