Transfer of protein templates in photoresist on glass chips into protein patterns on hydrogels. (A) Developed photoresist templates on glass chips. The developed photoresist templates were stored in a light-protected environment for approximately six months prior to hydrogel fabrication. (B) Protein patterns on hydrogels were visualized using fluorescent gelatin. Fluorescent gelatin was transferred from glass chips using polydimethylsiloxane (PDMS) spacers to define the hydrogel thickness. Scale bars denote 25 µm.
