The use of field effect surface charge in the control of fluidic networks – applications in life science

Leuven | More than two weeks ago

Join us in revolutionizing microfluidics with cutting-edge technology at imec!
Imec is at the forefront of innovation in microfluidics, leveraging silicon-based fabrication technology to push the boundaries of the field. Now, we intend to tackle the challenges in fluidic control, dispersion reduction, and surface reactions resulting from the limitations of rigid structural materials.
Our focus in this project is on harnessing the power of electric fields to control protonation on surfaces and affect the interaction of liquids and molecules with this surface. In this ambitious project, we intend to explore Imec's prowess in creating small electrodes with diverse geometries to improve fluidic handling. Our goal is to integrate this into a microfluidics circuit for comprehensive analysis, addressing the limitations posed by traditional silicon substrates.
What you'll be doing
Phase One:
• Design, fabricate and test devices with flat electrodes strategically placed in micro and nanochannels.
• Investigate the impact of varying material compositions on the effect.
• Explore how modifications influence processes such as solute dispersion, biomolecule adsorption/desorption, and liquid valving/gating.
• Build a demonstrator showcasing the device's ability to control dispersion, enhance resolution in electrophoretic separations, and influence biomolecule interactions.
Phase Two:
• Expand on collaborative efforts between life-science and energy teams.
• Develop 3D porous materials featuring a conductive core coated with insulating oxides.
• Leverage the advantages of increased surface area for reactions, enhanced actuation for pumps and valves, and a sieving structure enabling conformational changes in large-scale molecules.
