Abstract
Biomolecular and other interactions are analyzed with a simpler construction. A biotic sample is fixed to noble metal nanoparticles, and light is irradiated from a light source to the noble metal nanoparticles through an optical fiber. Light obtained after reflection of the irradiated light by the noble metal nanoparticles is introduced to one or more optical detecting units through another optical fiber. The optical detecting unit(s) separately measure the intensity of the input light in a second band including a maximum absorption wavelength, a first band covering a longer wavelength range than the range covered by the second band, and a third band covering a shorter wavelength range than the range covered by the second band.
