Electrokinetic methods for isolation, concentration, and purification of pathogenic bacteria from complex media. Fabrication of integrated microfluidics for front-end purification followed by genetic and immunological characterization.
The goal of this project is to design and construct a portable and cost effective magnetic resonance imaging (MRI) instrument that is capable of resolving features at microscale to image flow fields of complex fluids in capillary tubes.
We develop a new mechanism for changing the architecture of microfluidic channels during device operation. Two co-streaming fluids are separated through a temporal wall using targeted gel formation inside a microfluidic channel. We derive explanations for this mechanism including scaling arguments for the wall thickness.
