    摘要： An improved structure of a liquid drop emitter is provided which works to emit minute drops of liquid to deposit them in a dense array of dots on a substrate to produce a DNA chip, for example. The liquid drop emitter has a plurality of liquid inlets formed in rows in a staggered fashion, thereby allowing the liquid inlets to have a maximum possible area without any physical interference between adjacent two of them and also allowing outlet nozzles to be arranged in a dense array.

    摘要： A liquid droplet discharging piezoelectric device 1 provided with a cavity member 11 with a built-in cavity 3; an introduction member 13 having introduction channel 5 connecting with the cavity 3; and a nozzle member 12 having nozzle channel 4 connecting with the cavity 3 on a side opposite to the channel 5. This liquid droplet discharging piezoelectric device 1 is provided with an introduction port 6, attached to the introduction member 13, capable of introducing a liquid into the cavity 3 via the introduction channel 5, and a discharge port 7, attached to the nozzle member 12, capable of discharging as droplets a liquid filled in the cavity 3 via the nozzle channel 40. Even in a case where an amount of liquid droplets is of a nanoliter (nl) order, excellent stability and reproducibility are attained, and the unit can stably be operated when attached to an apparatus.

    摘要： A micropipette usable for producing a biochip inclusive of DNA micro arrays capable of arraying and fixing droplets of a micro-volume on a substrate in a high density includes a main body, at least one cavity for storing a sample, at least one ejection port, a piezoelectic/electrostrictive element mounted on the outer surface of the main body, and at least one sample inlet port for supplying sample from the outside. A sample that is temporarily stored in the cavity is discharged from at least one ejection port, by virtue of the movement of the piezoelectric/electrostrictive element, to outside of the micropipette via a through hole in a nozzle portion formed in the pipette main body. The nozzle portion through hole has three or more projection radially protruding from the center of the through hole and having a specific shape.
