Combination Ultrasonic- Dielectrophoretic Particle Traps for Particle Trapping and Sample Purification in a Microfluidic Channel

Marina O., Ward M.D., Kaduchak G., Los Alamos National Laboratory, US

Ultrasonic and dielectrophoretic particle manipulation has been studied for particle trajectory modification and particle trapping in microfluidic channels. We report a new approach of a combination of dielectrophoresis (DEP) and ultrasonic fields to trap and [...]

Highly Selective Capture and Transport of Rare Cells in Microfluidic Channels

Ward M.D., Grodzinski P., Los Alamos National Laboratory, US

Collection of rare target cells in clinical samples such as disseminated tumor cells in peripheral blood or fetal cells in maternal blood poses difficult challenges to currently available cell separation methods. A novel, two stage [...]
