  • Publication number: 20100213274
    Abstract: A microdroplet generation apparatus comprises an oscillation plate, a connection plate, a nozzle disc and a bonding material, wherein the nozzle disc is interposed between the oscillation plate and connection plate, and wherein the oscillation plate, connection plate and nozzle disc are joined with the bonding material. The oscillation plate and the connection plate respectively have a first through-hole and a second through-hole corresponding to each other. The nozzle disc has injection holes on the area corresponding to the first and second through-holes.
