Abstract:
1. A microfluidic driving apparatus for driving the fluid flowing in a microfluidic system comprising: a syringe, which comprises a barrel and a plunger, wherein said barrel is provided with an opening, and said plunger is capable of moving in the barrel; a plunger positioning member, which is mounted at inside or outside of said barrel and is capable of holding said plunger in a preset position; a connecting unit for connecting said syringe and said microfluidic system; and a porous impedance member, which is mounted inside said barrel, said microfluidic system or said connecting unit; wherein a pressure difference between said barrel and said microfluidic system is created to drive said fluid flowing inside said microfluidic system by relocating said plunger in said barrel to said preset position, and said fluid is regulated at a lower speed by using said impedance member.
