The electrical field grabs the nanowires and pulls them to the top where they align perpendicular to the electrode. The aligned nanowires skate along the electrodes so when they reach a well, drop into it.

The amount of wires in the perfect solution is is controlled with respect to the amount of wells so just a few wires stick to the chip beyond your wells.From Yale University College of Medicine and her co-workers studied the breasts tumors of 145 African-American and 177 white women to help expand characterize the pattern of alterations of genes known to relate to tumor development and be associated with worse prognosis.
