Plural probes spotted on a probe immobilization substrate are arranged such that the probes cannot be specified by a third party easily. When the plural probes are spotted on the probe immobilization substrate, a position where each probe is spotted is changed for each probe immobilization substrate to be prepared, whereby types of probes to be arranged in respective spot addresses are encrypted. The preset invention provides a spotter, a dispensing device to be used for the spotter, a probe immobilization substrate that is prepared using the spotter, and a detection device that decodes encrypted positions where the respective probes are spotted. |
