The invention describes a process for preparing a microtiter-microarray
device that includes a bottomless microtiter plate attached to the first
side of one or more substrates with microarrays of materials attached
thereto. The microtiter plate and the one or more substrates are attached
through one or more gaskets. Preferably, the microtiter plate is attached
to one face of the one or more gaskets by an irreversible water-tight
seal, and the first side of the one or more substrates is attached to the
opposite face of the one or more gaskets by a reversible, water-tight
seal.
