A spotter suitable for spotting a liquid containing low dispersibility particles in manufacturing the reactive detection chip is also provided. In the reactive detection chip, the number of probes can be stably controlled, and a three-dimensional array of the probes uniformizes the supply of a sample to the probes. Thus, the magnitude of signal components is stabilized, and signal components are stably increased, so that the S/N ratio is increased, and the detection capability of the DNA chip can be enhanced. The use of the spotter enables the chip to be manufactured more efficiently.Type: ApplicationFiled: February 28, 2005Publication date: November 17, 2005Applicant: Ebara CorporationInventors: Kenro Nakamura, Masahito Abe, Naoaki Ogure
