Self-folding nano- and micropatterned hydrogel tissue engineering scaffolds by single step photolithographic process

- A novel and fast sacrificial layer embossing method, for nanopatterning gel films.
- Method creates nanopatterned environmentally responsive hydrogel films.
- Double sided micro- and nanopatterned gel films are produced in one stage.
- Films will roll and unroll in response to changes in aqueous pH.
- Produces sub millimetre injectable and patterned cylindrical tissue scaffolds.
