  • Publication number: 20130314705
    Abstract: There is provided a method of measuring a diffusion characteristic value (for example, a diffusion constant) of a light-emitting particle using the scanning molecule counting method using the optical measurement with a confocal microscope or a multiphoton microscope. The inventive method of measuring a diffusion characteristic value of a light-emitting particle is characterized to measure light intensity from the light detection region with moving the position of the light detection region in the sample solution by changing an optical path of the optical system to generate light intensity data and to compute a diffusion characteristic value of the light-emitting particle based on a deviation time from a moving cycle time of the light detection region in an interval of generation times of two or more signals corresponding to a same light-emitting particle on the light intensity data.
