Nanoscale discovery brings 'lab on a chip' devices closer to reality

Abstract:
Making a breakthrough in "lab on a chip" technology, a University of Michigan biomedical engineering professor has discovered a new instance of such a nanoscale phenomenon that could lead to faster, less expensive portable diagnostic devices.



Buzz up!In our macroscale world, materials called conductors effectively transmit electricity and materials called insulators or dielectrics don't, unless they are jolted with an extremely high voltage.


Under such "dielectric breakdown" circumstances, as when a bolt of lightening hits a rooftop, the dielectric (the rooftop in this example) suffers irreversible damage.

But, this isn't the case at the nanoscale, according to a new discovery by Alan Hunt, an associate professor in the Department of Biomedical Engineering.
