Characterization of biomolecule polarizability in alternating electric fields

This internship project focuses on the experimental characterization and quantification of the electricalpolarizability of biomolecules such as DNA and proteins. The student willperform dielectrophoresis (DEP) capture experiments using microelectrode array devices and quantify biomoleculartrapping behavior using fluorescence microscopy. Experimental results will becompared to continuum-based electrokinetic models to extract effectivepolarizability parameters and assess the validity and limitations of existingtheoretical descriptions at the molecular scale. The work will involvefluorescence imaging, data analysis, and numerical modeling, providing hands-onexperience at the interface of biophysics, microfluidics, and electrokinetics.This project aims to improve the understanding of biomolecular polarizationmechanisms and contribute to the development of label-based and label-free DEPmanipulation techniques.
