BioED webinar 26 - Selim Hanay - Microwave Sensors for the Analysis of Single Cells and ...

Abstract The use of microwave frequencies offer the advantage of bypassing ion screening effects in liquid: this way internal material properties of analyte particles can be probed even for liquids with physiological levels of ion concentrations. By building sensors based on microwave resonators, we will present three different sensing scenarios . First, we will review the applications of microwave sensing in cellular sizing. Then, we will discuss the extraction of dielectric permittivity of microparticles by an integrated sensing approach which combines microwave sensing with low-frequency impedance cytometry. With this approach, it becomes possible to differentiate spherical polystyrene particles from soda lime glass particles. Finally, we will present a nanopore-integrated microwave sensor for capacitive detection of nanoparticles in liquid. Bio Selim Hanay obtained his Ph.D. degree in Physics from Caltech in 2011 during which he developed nanomechanical sensors capable of detecting and weighing single protein molecules in real time. He continued his research at Caltech in post-doctoral capacity for two years, before joining Bilkent University, Turkey, as an Assistant Professor in 2013. His current research focuses on the detection of viruses and nanoparticles using nanomechanical mass spectrometry under atmospheric conditions, and microwave sensing of nanoparticles in microfluidic systems. He is the recipient of incentive awards from several research organizations such as TUBITAK (Turkish NSF), Turkish Academy of Sciences, Bilim Akademisi and IEEE Turkey Section, as well as the Distinguished Teaching Award of Bilkent University. His research group is supported by several national grants, and EU programs such as ERC Starting and Proof-of-Concept Grants. He is currently an Associate Professor at Bilkent University and a Visiting Associate at Caltech.
