    Jaffe, Alex TMassachusetts Institute of Technology2018

    This thesis explores the use of dielectrophoresis to discern the electrical properties of single cells by observing them at multiple frequencies. We first simulate experimental conditions to show that as we increase the number of measured frequencies, we are able to better discriminate among …
