Abstract:
1. An optical analysis device which detects and analyzes light from a light-emitting particle dispersed and moving at random in a sample solution using an optical system of a confocal microscope or a multiphoton microscope, the device comprising: a light detection region moving portion which moves a position of a light detection region of the optical system in the sample solution by changing an optical path of the optical system; a light detecting portion which detects intensities of components of two or more wavelength bands of light from the light detection region; and a signal processing portion which detects individually signals from each light-emitting particle in the intensities of the components of the two or more wavelength bands of the light detected with the light detection portion with moving the position of the light detection region in the sample solution, and identifies a kind of the detected light-emitting particle based on the intensities of the components of the two or more wavelength bands of the signals of the light of the light-emitting particle.
