Microfluidic chip for analysis of single cells
(PHYSorg.com Chemistry)

A few little cells that are different from the rest can have a big effect. For example, individual cancer cells may be resistant to a specific chemotherapy-causing a relapse in a patient who would otherwise be cured. In the journal Angewandte Chemie, scientists have now introduced a microfluidics-based chip for the manipulation and subsequent nucleic-acid analysis of individual cells. The technique uses local electric fields to highly efficiently `trap` the cells (dielectrophoresis).
