Abstract

Microfluidics devices deal with volumes of fluid on the order of nanoliters or picoliters (10-12 liter). The devices have dimensions ranging from millimeters down to micrometers. They have made significant impact on various science and engineering disciplines, including biology, chemistry, and biomedical engineering, due to its many advantages, such as low sample consumption, precise control of micro-environments, and a high degree of integration and automation. We developed a low-cost and high-resolution micro-fabrication system that enables quick and inexpensive manufacturing of master molds for fabricating microfluidic devices via soft-lithography. The system utilizes ultraviolet LED as a light source and dry film photoresist as patterning materials. It achieves feature resolution down to 30μm, aspect ratio≈1, and sidewall angle > 80⁰, which meet the requirements of typical microfluidic applications.
