Tumor cell characterization and classification based on cellular specific membrane capacitance and cytoplasm conductivity

This paper reports a microfluidic system that enables the characterization of tumor cell electrical properties where cells were aspirated through a constriction channel (cross-section area smaller than that of biological cells) with cellular impedance profiles measured and translated to specific membrane capacitance (Cspecific membrane) and cytoplasm conductivity (σcytoplasm). Two batches of H1299 cells were quantified by the microfluidic platform with different constriction channel cross-section areas, recording no differences with statistical significance (p
