DNA Threaded Through Nanopipette

Collaborating researchers—chemists at Imperial College London, and electrical and biomedical engineers at the University of Minnesota—have devised means for driving strands of DNA through a nanopore trap at a 1,000 fold increase in the speed detecting efficiency of sequencing. The process still relies on fluorescent probes and an electron multiplying camera, but the drive force is a dielectrophoretic (i.e. AC and DC) current through a gold tipped nanopipette. MORE
