Problem addressed

Mechanical and electrical properties exhibit cell phenotypes in different aspects. Multiparametric phenotyping of individual cells for both mechanical and electrical properties can achieve a more promising prognostic/diagnostic strategy.

  • Cell elastic modulus are well known to be related to malignancy and invasiveness of tumor cells and immunological state of immune cells.
  • The electric permittivity reflects intercellular communication, cell adhesion, and nutrient absorption.
  • Using artificial intelligence to resolve the signal acquired from electrodes embedded under the microchannel, it can quantify uncoupled geometric (cell size), mechanical (elastic modulus) and electrical (dielectric constant) properties of each cell flowing in a microfluidic device, at a throughput comparable to the commercial flow cytometry.
