We demonstrate a method to create microscale chitosan fiber by combining a microfluidic device and in situ formation of a 2D shape by winding around the frame. The diameter of these fibers was found to range from a few tenths to hundredths of a micrometer, and the process was optimized to fabricate long (> 1 meter) fibrous chitosan fibers and to wind them. To estimate the capability of these fibers to act as scaffolding for liver tissue formation, HepG2 cells, which are generally used as model
