A multi-electrode array with individually isolated electrodes each configurable for a target-containing carrier and a method for fabricating the array are disclosed. In an exemplary embodiment, the array includes a substrate； and a plurality of electrodes disposed on the substrate. Each electrode of the plurality of electrodes has a conductive tip-end and an insulated remainder. A first electrode of the plurality of electrodes has a first configuration selected to bring a conductive tip end of the first electrode in proximity to a first target structure, and a second electrode of the plurality of electrodes has a second configuration selected to bring a conductive tip end of the second electrode in proximity to a second target structure. The first configuration and the second configuration are different. A first contact of the plurality of contacts may be electrically coupled to the first electrode through the substrate.
