Abstract:
An apparatus for depositing fluid dots on a receiving surface in an array, comprising:a deposit device cooperatively related a fluid source including biological material; a drop-carrying element coupled to and displaced by the deposit device; a fluid-retaining structure, co-operatively arranged with the drop-carrying element, constructed to retain fluid including biological material by surface tension, the fluid-retaining structure being constructed and shaped for at least partial immersion into a well including the biological material; a transport mechanism for positioning the deposit device and the drop-carrying element at a precisely referenced position over the receiving surface; and a drive mechanism for moving the drop-carrying element, relatively through the fluid-retaining structure to receive the fluid including the biological material, in deposition motion toward and away from the surface.
