IMEP-LaHC is one of the leading laboratories in the field of integrated optics, and more specifically of photonics on glass. Striving for innovation, one of our goals is to fabricate integrated devices dedicated to sensing applications such as bacteria detection. Indeed, monitoring of bacterial concentration is critical in various fields such as agri-food industry or environmental monitoring. For these partners, the design and fabrication of a compact, reusable and portable optical sensor would be a major step for efficient and continuous in-situ measurements.

Dielectrophoretic precipitation of airborne particles. Joseph D. Duff , University of Louisville. Experimental and numerical modeling studies of particle separation from a gas stream using a dielectric force have shown that dielectrophoresis is an appropriate mechanism for the filtration of a particulate matter from a particle laden gas stream.
Dielectrophoresis—the tendency of a material of high dielectric permittivity to migrate in an electrical field gradient to a region of maximum field strength—provides an ideal motive force for manipulating small volumes of biological analytes in microfluidic microsystems. The work described in this thesis was based on the hypothesis that dielectrophoresis could be exploited to provide high-resolution cell separations in microsystems as well as a means for the electrically-controllable manipulation of solid supports for molecular analysis. It was shown that separation of the polystyrene beads was based on the differences in their effective dielectrophoretic properties.
Cell-released, membrane-encapsulated extracellular vesicles EVs serve as a means of intercellular communication by delivering bioactive cargos including proteins, nucleic acids and lipids. EVs have been widely used for a variety of biomedical applications such as biomarkers for disease diagnosis and drug delivery vehicles for therapy. Herein, this study reports a novel method for label-free, contact-free isolation and recovery of EVs via optically-induced dielectrophoresis ODEP on a pneumatically-driven microfluidic platform with minimal human intervention.
