In this research, we report solid-state crosslinking-based transparent hydrogels with controlled swelling and predefined micro/nanoscale geometry. We employed i) the solid-state crosslinking between water soluble polymer and crosslinker polymer, and ii) the subsequent process for breaking physical crosslinking (e.g., hydrogen bonding) among waters-soluble polymer chains. Finally, we demonstrate that the hydrogel nanofiber structures can be beneficial for a variety of biomedical applications such as 3-dimensional cell culture.
