Figure 1

A schematic of the surface-initiated assembly process. (a) FN homodimers in their solution conformation were adsorbed onto a hydrophobic PDMS stamp where they obtained a partially unfolded conformation. (b) The FN dimers were transferred in the unfolded state to a PIPAAm surface via microcontact printing to create array of patterned nanofibers. (c) The PIPAAm was hydrated at an elevated temperature and allowed to cool below its LCST resulting in the release of an assembled FN nanofiber.
