  • Title: Review: Dielectrophoresis in cell characterization.
    Author: Henslee EA.
    Journal: Electrophoresis; 2020 Nov; 41(21-22):1915-1930. PubMed ID: 32735707.
    Abstract:
    Many cellular functions are affected by and thus can be characterized by a cell's electrophysiology. This has also been found to correspond to other biophysical parameters such as cell morphology and mechanical properties. Dielectrophoresis (DEP) is an electrostatic technique which can be used to examine cellular biophysical parameters through the measuring of single or multiple cell response to electric field induced forces. This label-free method offers many advantages in characterizing a cell population over conventional electrophysiology methods such as patch clamping; however, it has yet to see mainstream pharmacological application. Challenges such as the transdisciplinary nature of the field bridging engineering and the biological sciences, throughput, specificity as well as standardization are being addressed in current literature. This review focuses on the developments of DEP-based cell electrophysiological characterization where determining cellular properties such as membrane conductance and capacitance, and cytoplasmic conductivity are the primary motivation. A brief theoretical review, techniques for obtaining these cell parameters, as well as the resulting cell parameters and their applications are included in this review. This review aims to further support the development of DEP-based cell characterization as an important part of the future of DEP and electrophysiology research.
