1. A hanging drop array plate comprising:
- a top surface and a bottom surface, said top surface bounded by one or more edges,a plurality of holes, each said hole extending from an opening in said top surface to an outlet at said bottom surface, said plurality of holes configured to accommodate a corresponding plurality of hanging drops formed by application of a liquid through said opening of each of said holes, wherein a single drop hangs from a respective one of each of said holes and distends under the influence of gravity beneath said outlet thereof to enable the culturing of cells therein,said bottom surface including a plateau feature surrounding each of said holes, said plateau feature configured to restrain a hanging drop to a confined region about the respective said hole; and
said top surface including an upper reservoir configured to receive a body of liquid restricted from said plurality of holes for maintaining a substantially stable humidity above said plurality of holes, said upper reservoir disposed along one or more of said edges of said top surface.
