Abstract
The invention relates to a microfluidic device. The microfluidic device comprises a fluid chamber comprising a particle retention region for retaining at least one particle, such as a cell. The microfluidic device also comprises a plurality of electrodes extending into the particle retention region for applying a dielectrophoretic (DEP) force to controllably move the particle within the particle retention region. The invention also relates to methods of using the microfluidic device to controllably move the particle within the microfluidic device and to monitor, observe, or measure a parameter of the particle. The particle movement may be caused by a DEP force and/or a fluidic force.
