  • Publication number: 20060014271
    Abstract: An inexpensive apparatus and method of fabricating completely polymeric (e.g., SU-8, PMMA, and PEEK) microfluidic reactors suitable for the synthesis of chemicals, particularly nanoparticles (e.g., mono, bi, tri, alloy, core-shell, polymeric, and metal-polymer nano-particles), is disclosed. A high precision process uses polymeric microfluidic patterning techniques and a new microfluidic sealing technique, referred to as “flexible semi-solid transfer,” to fabricate high aspect ratio polymeric micro-reactors. In one embodiment, high quality microfluidic channels are patterned onto a support substrate. The microfluidic structure is then sealed by transferring a polymeric material from a sacrificial substrate to the microfluidic structure, and cured. Then, the structure is bonded to a second support structure to form a micro-reactor.
