The University of Twente invites applications for a PhD position focused on single-molecule protein nano dielectrophoresis. This innovative research will involve the development of a platform for label-free characterization of single biomolecules and nanoparticles using advanced nanofabrication and optical measurement techniques. The PhD candidate will engage in designing nanogap electrodes, conducting complex optical measurements, and working in cleanroom facilities. Applicants should have an MSc in applied physics, electrical engineering, biomedical engineering, nanotechnology, or related fields. Experience in nanofabrication or optics is encouraged but not required.
