Abstract
Methods of releasing and analyzing substrates such as DNA, comprising: a) covalently or ligandly binding substrate to a first electrode via a release group, which release group is cleavable in response to applied energy; b) introducing an electrical field so as to establish a charge potential between the first electrode and a second electrode separated by a vacuum or gas phase from the first electrode, the strength of such field sufficient to bristle said covalently-bound or ligandly-bound substrate; and c) applying sufficient energy directly to the release group to cleave the release group and release the substrate into a vacuum or gas phased
