Abstract
The microfluidic dispensing device includes a patterned seal having a specified arrangement of holes and groves, and an connection plate having passages corresponding to the holes in the patterned seal. The patterned seal and the connection plate are configured to stack onto a planar substrate, such as a glass slide, and are sealed together and against the substrate by a negative pressure, or vacuum, applied through the connection plate. When the patterned seal is secured against the substrate, the grooves in the patterned seal form a network of channels for delivering fluids to specified regions on the substrate. The connection plate preferably includes one or more connectors for attaching fluid and/or vacuum lines, and optionally includes one or more sensors to monitor operation of the device. The system of the present invention also includes a device for automatically assembling and handling the microfluidic dispensing device.
