摘要:
Disclosed herein is a microchip including a substrate and a sample flow path within the substrate. The sample flow path includes a changing flow path and a microtube connected to the changing flow path. The changing flow path is configured to change a cross sectional shape of the sample flow path from a quadrangular shape at a first end to a circular shape at a second end. The microtube is connected to the second end of the changing flow path and is disposed within the substrate.

A fine particle measuring method of performing optical measurement of fine particles introduced into a plurality of sample fluidic channels provided at predetermined distances on a substrate by scanning light to the sample fluidic channels is disclosed. The method includes: sequentially irradiating the light to at least two or more reference regions provided together with the sample fluidic channels; detecting a change of optical property occurring in the light due to the reference regions; and controlling timing of emission of the light to the sample fluidic channels.
