A fluidic device is provided that includes a body and a contiguous electrically conductive layer. The body has interior and exterior surfaces. The interior surface defines at least a well and a fluid-transporting feature, e.g., a microfeature in fluid-communication with the well. The well has a sidewall and an exterior opening terminating at the exterior surface. The contiguous electrically conductive layer is located on at least the sidewall of the well and selected regions of the interior and exterior surfaces so as to form a contact pad region on the exterior surface in electrical communication with any fluid within the fluid-transporting feature. Also provided is a method for forming a fluidic device.
