Droplet discharging device, apparatus for manufacturing microarray, and method for manufacturing microarray

摘要

A small droplet discharging device is provided capable of producing high- density arrays. The droplet discharging device comprises a first substrate comprising a plurality of reservoir chambers for holding a liquid, a second substrate comprising a plurality of discharge units comprising supply openings for receiving a supply of a liquid stored in the reservoir chambers, pressurizing chambers for applying a pressure to the liquid supplied from the supply openings, and discharge openings for discharging the liquid pressurized in the pressurizing chambers to the outside, and a third substrate sandwiched between the first substrate and the second substrate and comprising channels for connecting the plurality of reservoir chambers with the plurality of supply openings corresponding thereto, wherein the plurality of supply openings provided in the second substrate are arranged such that relative positions thereof have a zigzag disposition.
