Bidirectional Flow Field for Separation of Molecules and Particles
The aim of this master’s thesis project is to explore, characterize and develop strategies to implement a new diffusion-based method for separation of biochemical species. This approach leverages bidirectional flow, a unique flow field generated by non-uniform electroosmotic flow.
- Characterize the surface charge properties of several substrates for different buffer conditions. - Study and characterize the diffusion convection transport of particles and molecules in a bidirectional flow field. - Identify and test several methods to create surface patterns of hydrophobic and oleophobic regions. - Study and characterize the electroosmotic flow of non-aqueous solutions. - Explore alternative approaches to control dynamically the zeta potential distribution of a substrate, including light-driven and electrical actuation.
The student must have a strong interest in Transport Phenomena / Surface Chemistry Analytical Chemistry. He/She must have a background in at least one of the following disciplines: physics, chemical, mechanical engineering, electrical engineering (micro/nanoengineering track) or biomedical engineering. The student must be motivated, self-driven and keen to work in a biomedical microtechnology environment.
