Abstract

One aspect of the invention provides a well plate. The well plate may comprise a substrate, a primary structure attached to a first side of the substrate and a light absorbent secondary structure attached to the first side of the substrate. The primary structure may comprise a plurality of walls wherein the plurality of walls and the substrate together define a plurality of wells. The secondary structure may comprise, within each of the plurality of the wells, a plurality of sub-walls wherein each plurality of sub-walls and the substrate together define a plurality of sub-wells.
