Continuous-Flow Dielectrophoretic Bioparticle Manipulation
Funding: DOE, NSF
We are developing unique microchannel geometries that enable efficient and rationally designed continuous-flow dielectrophoretic manipulation of bioparticles as part of integrated biotoxin analysis systems. See the dielectrophoresis text chapter for technical background on dielectrophoresis.
