Dispenser or applicator forming localized deposits of biological solutions, comprises flat silicon lever including a central body and pointed tip with slit or groove

摘要

Dispenser or applicator forming localized deposits of biological solutions, comprises a flat lever (1) in silicon, with a central body and a pointed (3) tip region (2) in which a slit or groove (5) is formed. Dispenser or applicator forming localized deposits of biological solutions, comprises a flat lever (1) in silicon, with a central body and a pointed (3) tip region (2) in which a slit or groove (5) is formed. The slit or groove extends from the tip to a reservoir formed in the central body. This is an open- or closed cavity originating at a main surface of the central body. It is a continuous opening between the main opposite surfaces (11, 12) of the central body. Variations of the basic design are proposed. Typical microcircuit fabrication technologies are employed. An Independent claim is included for the method of fabrication.
