MICROFLUIDIC APPARATUS, METHOD OF DETECTING SUBSTANCE IN MICROFLUIDIC APPARATUS, AND LIGHT EXTRACTION APPARATUS

摘要

A microfluidic apparatus includes a base substrate (300); a microfluidic device (400) on the base substrate (300) and including a plurality of micro fluidic channels (410); a plurality of light sources (200) of different colors respectively emitting light of different wavelength ranges; a light extraction apparatus (1000) for extracting light respectively from the plurality of light sources (200) of different colors and a plurality of photosensors (500). The light extraction apparatus (1000) includes a light guide plate (100) having a plurality of light incident portions (112) for respectively receiving light respectively incident from the plurality of light sources (200) of different colors, the plurality of light incident portions (112) being on a side of the light guide plate (100) away from the microfluidic device (400); and a plurality of light extractors (120) on the light guide plate (100). The microfluidic apparatus can detect multiple substances simultaneously.
