ABSTRACT:
An apparatus and method for selectively attracting and inhibiting attraction of at least one predetermined molecule to a site in a molecular detection device utilizes a first electrode and a second electrode proximate to the site. The first electrode selectively generates a first electric field proximate to the site in response to a first signal applied thereto. The first electric field provides an attractive force to attract the at least one predetermined molecule toward the site. The second electrode selectively generates a second electric field proximate to the site in response to a second signal applied thereto. The second electric field selectively inhibits attraction of the at least one predetermined molecule toward the site by providing a repulsive force which dominates the attractive force provided by the first electric field.
