<p><P>PROBLEM TO BE SOLVED: To acquire a large amount of change in both absorbance changes in absorption peaks, results of measurement by Localized Surface Plasmon Resonance (LSPR), and shifts in absorbance peak wavelengths, results of measurement by interference spectroscopy. <P>SOLUTION: A tip 1 for analysis is provided with both a porous layer 3 in which a large number of pores 6 extending in directions in parallel with one another are arranged at approximately regular intervals and in which the pores 6 are open in one surface and a metal layer 5 formed on the opening surface 4 of the porous layer 3. The metal layer 5 is formed on the opening surface 4 of the porous layer 3 and pore wall surfaces in the vicinity of opening parts of the pores 6. The porous layer 3 is preferably an anode oxidation alumina coating. The metal layer 5 is constituted by layering an underlayer including at least one type selected from among Cr, Ti, and Ni and a surface layer including at least one type selected from among Au and Ag in this order. Metal particulates are absent in the pores 6. When the adsorption of matter to surfaces of the tip 1 for analysis irradiates light to the tip 1 for analysis, the light irradiation is observed as absorbance changes and wavelength shifts due to localized surface plasmon resonance and interference effects. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
