Abstract

Recently there has been considerable interest in metal nanoparticles which are less than a few ten nanometers as labels for biomolecule detection in the field of molecular biology [1], However, it is difficult to detect weak scattering light from nanoparticles with an optical microscope. To overcome this problem, a detection method for nanoparticles magnified lager than diffraction limit in diameter by using photothennal effect with local surface plasmon resonance (LSPR) has been developed. To detect minimal phase shift around nanoparticles by photothennal effect, a single element interferometer using a beam splitter cube has been developed. This paper reports the phase shift by the photothennal effect and LSPR of metal nanoparticles has been observed by the single element interferometer.
