PHOTOTHERMALLY ACTUATED MICROVALVE AND LAB-ON-A-CHIP SYSTEM THEREOF

摘要

A lab-on-a-chip system using a microvalve with photothermal effect is provided to control fluid which flows in and out even in the environment in which dose not have pump or complex electronic circuit. A lab-on-a-chip system in which a microvalve is formed through photothermal effect comprises: a micro channel (1) in which fluid moves; a control chamber (2) in which medium is expanded or contracted and which is formed on the micro channel; and an elastic membrane (3) which makes the micro channel open and close by elasticity change.
