제목 Ultraviolet (UV)-curable polydimethylsiloxane (PDMS) for microfluidic chips
초록 Although thermally curable polydimethylsiloxane (PDMS) has been used as almost the sole material for microfluidic chip. Especially for flow lithography using PDMS microfluidic chips, it have shown some limitations. For example, undesired shrinkage of chip occurs due to the thermal expansion of masters used for replica molding. Also, interfacial delamination between two thermally-cured PDMS layers impede robust chip fabrication. Here we propose the utilization of UV-curable PDMS (X-34-4184) microfludic chip for flow lithography as an excellent alternative material of the conventional one. Our proposal offers three key advantages: 1) UV-curable PDMS exhibited almost the same oxygen permeability as the conventional PDMS. 2) The almost complete absence of thermal expasion of master facilitated fabrication of precise reverse duplication of microstructures. 3) UV-cured PDMS microfluidic chips were capable of much stronger interfacial bonding.
