The method is based 011 the force balance of particle motion in a horizontal straight micro channel with an electrode array built 011 its bottom wall for generating twDEP. The experimental validity was checked using sephadex particles and liposomes. The ICMF spectrums of two lung cancer cells with different metastatic stages were also measured, and their difference indicates that ICMF can be served as a phenotype for cell characterization.Cell characterization; Imaginary part of clausius-mossotti factor; Microfluidics; Travelling wave dielectrophoresis[SDGs]SDG3Electrophoresis; Ion exchange; Liposomes; Microfluidics; Wave transmission; Cell characterization; Clausius-mossotti factor; Electrode arrays; Electrorotation; Lung cancer cells; Particle manipulation; Particle motions; Travelling wave dielectrophoresis; Characterizationconference paper2-s2.0-84901759376https://www.scopus.com/inward/record.uri?eid=2-s2.0-84901759376&partnerID=40&md5=7a939f77ae6d4b15742f4cd86a92f38a
