This article succeeded to introduce a newmethod, that mimics the radio broadcasting, used amplitude modulation to deliver the low range frequencies to the cell membrane. Consequently, avoiding the ACEO which prevents the measurement of DEP spectrum. In addition to the use of quinine and NBBP as ion channel blockers along with the modulated dielectrophoresis technique enabled the measurement of membrane conductivity providing a low cost method.
