BIOSENSOR COMPRISING MULTIPLE CAPILLARY CHANNELS

摘要

PURPOSE: An optical biosensor comprising a multiple capillary channel is provided to quickly and accurately measure biomaterial through color intensity. CONSTITUTION: A biosensor(100) comprises: an inlet(12); a first capillary channel which is connected to the inlet and is formed in a first direction; a second capillary channel which is connected to the first capillary channel and is formed in a second direction; a third capillary channel which is connected to the second capillary channel and is formed in the first direction; and a sample reaction unit contacting the third capillary channel. The sample reaction unit reacts with a sample and changes color. The biosensor further comprises a carrier layer(40) and a cover layer(10).
