Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

The paper describes the design, modelling and experimental characterization of a micromachined impedance sensor for on-line monitoring of the viable yeast cell concentration (biomass) in a miniaturized cell assay. Measurements in a Saccharomyces cerevisiae cell culture show that the permittivity of the cell suspension depends linearly on the biomass concentration within the range of 0 to 9 g/l. In order to compensate the measurements for changes in the dielectric properties of the background electrolyte, the use of a three-electrode configuration in combination with a semi-permeable pHEMA membrane was explored. Measurements showed that the impedance of the hydrated pHEMA varies with only the background electrolyte conductivity, and not with the concentration of cells, indicating that pHEMA is suitable for this purpose. The optimal pHEMA membrane thickness was determined using finite element modelling.
