제목 Sequential replica molding technique for the fabrication of NOA microfluidic devices
초록 Although polydimthylsiloxane (PDMS) microfluidic devices are frequently utilized in microfluidic applications, this device has several limitations such as short-term modified surface condition, swelling in the presence of organic solvents and deformation under high pressure. To solve these problems, Norland Optical Adhesive (NOA) has been gained much attention as an alternative for PDMS. Here, we introduce a practical protocol for the fabrication of NOA microfluidic devices via a step-wise molding process. By using indirect molding of NOA on positive-pattered wafers, we were able to prevent damage to the wafers and reduce fabrication cost of wafers. We test the performance of NOA devices in oil-in-water droplet production using organic solvents and confirmed that the devices fabricated by sequential replica molding showed same performance compared with the devices fabricated with other methods.
