ABSTRACT:
Provided is a method of manufacturing a biochip using a droplet discharging device including a droplet discharging head having a cavity and a nozzle hole provided in communication with the cavity, and a liquid housing unit connected to the cavity via a passage, having the steps of filling a retention liquid which separates without getting mixed with the sample liquid into the liquid housing unit, the passage, and the cavity; injecting the sample liquid into the liquid housing unit; moving the sample liquid from the liquid housing unit to the cavity by discharging the retention liquid from the nozzle hole; stopping the discharge of the retention liquid at the moving step upon detecting with a sensor that the sample liquid reached a position adjacent to the nozzle hole; and delivering the sample liquid as droplets onto the object by discharging the sample liquid from the nozzle hole.
