To overcome this challenge, we have developed a sensing platform to independently obtain both the geometric and electric size of organic and inorganic particles, by combining impedance cytometry and microwave resonant sensing in a microfluidic chip. This way the microwave signal is normalized to yield an intrinsic parameter that depends only on permittivity. The permittivity can then be used for material classification or single-cell interrogation.EnglishImpedance cytometryMicrowave sensorsMicroplasticsDielectric characterizationClausius-Mossotti FactorSingle-cell analysisMaterial identificationConference Paper10.1109/IMBioC56839.2023.103051049781665492171
