MICROFLUIDIC DEVICE USING PROPERTIES OF INJECTED FLUID, A SURFACE TENSION, AND PRESSURE CONTROL OF A PRESSURIZING UNIT, AND A METHOD FOR INJECTING THE FLUID USING THE SAME

摘要

PURPOSE: A microfluidic device and a method for injecting a fluid using the same are provided to repetitively inject the fluid, to use one kind of fluid or heterogeneous fluid at the same time or independently, and to be used for various fields including a field of new drug development using cocktail therapy.;CONSTITUTION: A microfluidic device(1000) comprises: a dispenser(100); a storage chamber(300) which is connected to the dispenser and stores the fluid injected from the dispenser; and a ventilation channel(500) which is connected to the storage chamber. The dispenser includes a first transportation channel(10) injecting the fluid, a fluid storing unit(30) which is connected to the first transportation channel and the storage chamber, and a pressurizing unit(50) discharging the fluid to the storage chamber.;COPYRIGHT KIPO 2010
