According to the method of producing organic pigment fine particles of the present invention, when producing organic pigment fine particles by allowing two or more solutions at least one of which is an organic pigment solution in which an organic pigment is dissolved to flow through a microchannel, the organic pigment solution flows through the microchannel in a non-laminar state. Accordingly, the contact area of solutions per unit time can be increased and the length of diffusion mixing can be shortened, and thus instantaneous mixing of solutions becomes possible. As a result, nanometer-scale monodisperse organic pigment fine particles can be produced in a stable manner.

摘要:
A sensor chip includes a dielectric plate and a sensor portion having a metal layer deposited on a predetermined area on the dielectric plate. A photo-reactable labeling-substance of an amount corresponding to the amount of a substance to be detected in a sample binds to the sensor portion by contacting the sample with the sensor portion. The amount of the substance to be detected is obtained by irradiating the predetermined area with excitation light and by detecting light output from the photo-reactable labeling-substance in an enhanced electric field that has been generated on the metal layer by irradiation with the excitation light. The photo-reactable labeling-substance includes a photo-reactable substance enclosed by a light transmissive material that transmits light output from the photo-reactable substance to prevent metal quenching that occurs when the photo-reactable substance is located close to the metal layer.
