“…Silk fibroin solution was first spin-coated onto the silica substrate, then SF film was illuminated by ArF excimer laser through a patterned Cr mask. After developing the exposed area with distilled water, the patterned SF film showed diffracted colors with a minimum line width of 1 µm [99]. Another technique is soft lithography, which is based on molding and printing with an elastomeric stamp to realize pattern transfer from the template.…”

The biological performance of artificial biomaterials is closely related to their structure characteristics. Cell adhesion, migration, proliferation, and differentiation are all strongly affected by the different scale structures of biomaterials. Silk fibroin (SF), extracted mainly from silkworms, has become a popular biomaterial due to its excellent biocompatibility, exceptional mechanical properties, tunable degradation, ease of processing, and sufficient supply. As a material with excellent processability, SF can be processed into various forms with different structures, including particulate, fiber, film, and three-dimensional (3D) porous scaffolds. This review discusses and summarizes the various constructions of SF-based materials, from single structures to multi-level structures, and their applications. In combination with single structures, new techniques for creating special multi-level structures of SF-based materials, such as micropatterning and 3D-printing, are also briefly addressed.

“…3B), indicating that the peptide scission is accompanied by structural transition from β-sheet to random coil or helix (Fig. 3 C, iii and SI Appendix , Table S1) (49,52). The latter case brings more molecular rearrangement and an associated larger effect on the localized stress field, indicating that crystalline silk-based wrinkle patterns are more susceptible to UV light than amorphous silk (Fig.…”

Protein micro/nanopatterning has long provided sophisticated strategies for a wide range of applications including biointerfaces, tissue engineering, optics/photonics, and bioelectronics. We present here the use of regenerated silk fibroin to explore wrinkle formation by exploiting the structure–function relation of silk. This yields a biopolymer-based reversible, multiresponsive, dynamic wrinkling system based on the protein’s responsiveness to external stimuli that allows on-demand tuning of surface morphologies and properties. The polymorphic transitions of silk fibroin enable modulation of the wrinkle patterns and, consequently, the material’s physical properties. The interplay between silk protein chains and external stimuli enables control over the protein film’s wrinkling dynamics. Thanks to the versatility of regenerated silk fibroin as a technological substrate, a number of demonstrator devices of varying utility are shown ranging from information encoding to modulation of optical transparency and thermal regulation.

“…Some researchers went further by replacing the current resists by biosourced polymers soluble in aqueous solutions. Takei et al used derivatives of polysaccharides as negative tone resist for electron beam (e-beam) lithography [6][7][8][9] or for extreme ultra-violet (EUV) lithography 9 whereas Kim et al tested silk as positive and negative tone resists for e-beam 10 or EUV lithography 11 . The polysaccharides of Takei et al were chemically modified with acryloyl groups.…”
