Abstract:
1. A microfluidic system comprising: a microfluidic device comprising a chamber which contains a fluid sample, a channel which is connected to the chamber and through which the fluid sample flows, and a valve which controls flow of the fluid sample through the channel, the valve comprising a phase transition material; an irradiation apparatus which irradiates electromagnetic energy; a diffuser which diffuses and distributes in various directions the electromagnetic energy irradiated by the irradiation apparatus in a predetermined direction to an irradiation region of the microfluidic device, such that the electromagnetic energy after passing through the diffuser has an increased diffusion angle and decreased intensity variation according to diffusion angles, as compared to the electromagnetic energy prior to passing through the diffuser; and a lens which is provided between the diffuser and the valve, to concentrate light passing through the diffuser and irradiate the light to the valve of the microfluidic device, wherein the lens is adhered to an exterior surface of, or injection-molded integrally with the exterior surface of, the channel of the microfluidic device.
