Preliminary Detailed Design
Team Vision for Preliminary Detailed Design Phase
Our team's goals for this phase were to establish the voltages and frequencies needed to create the separation of cells in the Automated Microfluidic Cell Separator. Our second goal was to successfully complete a feasibility cell separation using materials provided to us before making purchases ourselves.
Although neither of these goals were fully reached, each one had significant progress. In terms of finding the voltages and frequencies, our team has begun extensive research of peer reviewed articles. This will continue into the Detailed Design Phase. Our first experiment was successful in making a dielectrophoretic force on polystyrene particles by using a homemade microfluidic device. This shows proof of concept, and leads our team into the Detailed Design Phase with confidence to improve our process and keep moving forward.

Flow SimulationFlow through the channel was modeled using COMSOL finite elements software.
Note: The mesh size was the finest COMSOL can produce.
