Devices and methods for performing assays on materials, particularly biological materials, are provided. The devices and methods make use of self-sealing members, which can be applied to a flat surface to form wells to facilitate immobilization of materials on the flat surface, then removed to yield a flat surface that facilitates the performance of processes on and/or detection of the immobilized material.
