| Abstract: | Systems and methods for combining dielectrophoresis, magnetic forces, and
hydrodynamic forces to manipulate particles in channels formed on top of
an electrode substrate are discussed. A magnet placed in contact under
the electrode substrate while particles are flowing within the channel
above the electrode substrate allows these three forces to be balanced
when the system is in operation. An optical detection scheme using
near-confocal microscopy for simultaneously detecting two wavelengths of
light emitted from the flowing particles is also discussed. |
