MICROFLUIDIC CHIP FOR TESTING CELL CHEMOTAXIS AND A METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A microfluidic chip for testing cell chemotaxis and a method for manufacturing the same are provided to prevent irregular flow of fluid and to enable stable diffusion. ;CONSTITUTION: A microfluidic chip comprises: a first channel(110) in which chemotaxic sample solution is injected and a second channel(120) in which a cell solution is injected; an upper substrate(100) having a barrier for forming a cavity(102) between the first and second channels; and a lower substrate(200) having a junction channel of certain depth. A method for manufacturing the microfluidic chip comprises: a step of forming the first and second channels; a step of forming the substrate; a step of separating the upper substrate from a molding plate; a step of contacting the chemotaxic solution and sample solution to form the junction channel; and a step of assembling the upper and lower substrates.;COPYRIGHT KIPO 2011
