MICROFLUIDIC DEVICE IN WHICH CONCENTRATION GRADIENT AND TEMPERATURE GRADIENT ARE SIMULTANEOUSLY CREATED

摘要

The present invention relates to a microfluidic device in which a concentration gradient and a temperature gradient are simultaneously created in a detection channel of a microchannel and, more specifically, to a microfluidic device comprising a microfluidic channel for a sample and a pair of microfluidic channels for tempreature adjustment. The microfluidic channel for a sample includes: two inlets; a gradient forming region for separating each fluid which is injected into the inlets, into multiple microchannels having a different concentration gradient; a detection channel for joining and moving the fluid separated into the multiple microchannels after passing the gradient forming region; and an outlet for discharging the fluid passed the detection channel. The pair of microfluidic channels for temperature adjustment, wherein each channel is formed in parallel on both sides of the detection channel of the microfluidic channel for a sample by being spaced out in a prefixed interval with the detection channel, and includes: an inlet; an outlet; and a microchannel through which a fluid injected into the inlet moved to the outlet, such that heating mediums having a different temperature are circulated.;COPYRIGHT KIPO 2014
