Dielectric Property Characterization of Liquid Media Using an Open-Ended Probe Within a Microfluidic Chip

Abstract

https://doi.org/10.18280/i2m.190301 ABSTRACT: Received: 24 October 2019 Accepted: 2 March 2020 This article reports an open-ended coplanar waveguide line (OE-CPW) allowing the characterization of a liquid medium by dielectric spectroscopy within the 0.4-6 GHz frequency range. This proposed technology allows characterization of a medium placed in an integrated microfluidic channel located at the end of the CPW line. The medium under test occupies a volume of analysis of less than one nanoliter, scale allowing measurements of one to a few biological cells.
