摘要： A distribution of AC electric field regularly arranged in a cell is formed while storing a sample having particles dispersed in a medium in the cell, whereby the particles are dielectrically migrated in the medium to generate a diffraction grating by density distribution of the particles. Diffracted light generated by irradiating the diffraction grating by density distribution with measuring light is detected, and evaluation of dielectrophoretic intensities of the particles and/or the medium is performed from the detection result. According to this method, evaluation of dielectrophoretic characteristics can be performed without adhering a phosphor to particles, and since even a particle small in size can achieve a detection level by collecting a number of such particles to form a diffraction grating, dielectric characteristics of microparticles of several nanometers in diameter can be thus quantitatively measured with high sensitivity.

摘要： The invention provides an optical measuring device capable of performing measuring using a transient diffraction grating by only adjusting probe light, and a nanoparticle measuring device using the same principle as the optical measuring device. An optical measuring device includes: a power supply 15; a container 11 that stores a sample; a pair of electrodes 13 and 14 that generate an electric force line distribution in which areas having high electric force line density and areas having low electric force line density are regularly arranged; a dielectrophoresis control unit 19 that controls the generation of a transient diffraction grating using dielectrophoresis of particles in the sample caused by applying the voltage to the pair of electrodes 13 and 14 and a variation in the transient diffraction grating due to the diffusion of the particles in the sample according to a variation in the applied voltage; a light source 16 emitting light to the transient diffraction grating; and a plurality of photodetectors 18 detecting diffracted light generated by the transient diffraction grating. In the optical measuring device, the particles are evaluated on the basis of a variation in the intensity of the diffracted light generated by the transient diffraction grating. Further, for example, the particle diameter of a nanoparticle is measured by the same principle as the optical measuring device uses. As a result, it is possible to increase the intensity of a signal and to improve the sensitivity and the S/N ratio, as compared to a dynamic scattering method.
