    Abstract: There is provided a single particle detection technique based on a scanning molecule counting method, enabling individual detection of a single particle using light measurement with a confocal or multiphoton microscope, and quantitative observation of conditions or characteristics of the particle. The inventive technique of detecting a single particle in a sample solution detects light containing substantially constant background light from a light detection region with moving the position of the light detection region of the microscope in a sample solution to generate time series light intensity data; and detects individually a light intensity reduction occurred when a single particle which does not emit light (or a particle whose emitting light intensity in a detected wavelength band is lower than the background light) enters in the light detection region in the time series light intensity data as a signal indicating the existence of each single particle.

    Abstract: There is provided an optical analysis technique enabling the detection of the condition or characteristic of a particle to be observed contained at a low concentration or number density in a sample solution using a light-emitting probe. The inventive optical analysis technique uses an optical system capable of detecting light from a micro region in a solution, such as an optical system of a confocal microscope or a multiphoton microscope, to detect the light from the light-emitting probe having bound to a particle to be observed while moving the position of the micro region in the sample solution (while scanning the inside of the sample solution with the micro region), thereby detecting individually the particle crossing the inside of the micro region to enable the counting of the particle(s) or the acquisition of the information on the concentration or number density of the particle.

    Abstract: There is provided a single particle detection technique based on the scanning molecule counting method which individually detects single particles using light measurement with a confocal or multiphoton microscope, where the existences of a non-light-emitting particle and a light-emitting particle can be detected while being discriminated from one another in a sample solution. The inventive technique of detecting a single particle detects light from a light detection region during moving the position of the light detection region of the microscope in a sample solution containing a non-light-emitting particle and a light-emitting particle to generate time series light intensity data; and detects in the time series light intensity data a light intensity increase relative to background light intensity as a signal indicating the existence of the light-emitting particle and a light intensity reduction relative to the background light intensity as a signal indicating the existence of the non-light-emitting particle.
