<p><P>PROBLEM TO BE SOLVED: To detect the fluorescence, which is emitted from fluorescent dye by irradiation with exciting light with a wavelength of about 500 nm, with high precision in a nucleic acid analyzing device. <P>SOLUTION: In the nucleic acid analyzing device having a metal body producing localized surface plasmon by light irradiation, the material of the metal body consists of metal selected from any of ruthenium, iridium, palladium and rhodium or an alloy of the metals. These metals efficiently produce localized surface plasmon with respect to light with a wavelength of about 500 nm. Further, as the metals have extremely low ionization tendency and are very chemically stable, they can be used in a reaction solution for a long time. The present invention enables fluorescent measurement of nucleic acid stably and with high efficiency using light with the wavelength of about 500 nm. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
