An apparatus for dispersing a first plurality of conductive elongated nano-elements distributed within a carrier-fluid to assemble a conductive device made of a first charge-receptive area of a support surface to which at least one nano-element has attached, including: a nozzle through which the elongated nano-elements are directed such that the nano-elements pass through an electromagnetic field for imparting a preselected charge thereto, and toward at least the first charge-receptive area. The charge-receptive area is given a charge such that it attracts a first end-portion of one of the nano-elements. Also, a method of assembling a conductive device. Steps include: applying a first charge to the first charge-receptive area to attract a first end-portion of at least one nano-element; and dispersing from a nozzle, the plurality of elongated nano-elements distributed within a carrier-fluid initially contained in a reservoir, such that the nano-elements pass through an electromagnetic field for imparting a preselected charge thereto and toward the first charge-receptive area.
