Patterning and Functionalization of Thermoplastic Microchip for Automated High-throughput Microarray Gene Synthesis
نویسندگان
چکیده
The development of DNA microarray technology for high-throughput gene synthesis is hampered by poor sequence quality and inefficient gene assembly. We developed a programmable microchip using thermoplastic cyclic olefin copolymer (COC) functionalized with hydrophilic SiO2 thin film arrays, creating physically isolated picolitter reactors that constrain liquid via differential wettability. These functionalized SiO2-COC microchips exhibit enhanced droplet confinement and reduced edge-effect during in situ DNA synthesis, producing high-quality oligonucleotide arrays. Further, we demonstrated accurate and effective on-chip gene assembly from complex and heterogeneous microarray oligonucleotides by integrated amplification and assembly of sub-arrays in physically-isolated reaction chambers.
