Here, we present light-induced dielectrophoresis as a label-free approach for characterizing heterogeneous cell lines, specifically human mesenchymal stem cells (hMSCs). This paper describes a protocol for using and optimizing a microfluidic device with a photoconductive layer to characterize the electrical behavior of hMSCs without altering their native state.
