PROBLEM TO BE SOLVED: To easily find an object and reduce an observation time even if a sample has the object with a low concentration. SOLUTION: A probe 12a is preferably used and wholly scans a substrate on which a DNA is placed. When the probe 12a detects the DNA, a region in which the DNA exists is identified within a region in which a carbon nanotube of the probe 12a is disposed. The probe 12a is switched to a probe 12b, and positioned in the identified region. The region in which the DNA exists is identified within a region in which the carbon nanotube of the probe 12b is disposed. The probe 12b is switched to a probe 12c. The region in which the DNA exists is narrowly identified. Finally, the probe 12c is switched to a probe 12d having one carbon nanotube attached at an end. The region in which the DNA exists is detected by the probe 12c, sequentially scanned and measured by a control section 22. COPYRIGHT: (C)2006,JPO&NCIPI
