Silk inverse opals
A silk inverse opal that demonstrates a pseudo-photonic bandgap in the visible spectrum and show its associated structural colour beneath biological tissue is presented. The author also leverages silk’s facile dopability to manufacture a gold nanoparticle silk inverse opal and demonstrate patter...[ Learn more ]

Precise Protein Photolithography (P3): High Performance Biopatterning Using Silk Fibroin Light Ch...
A wafer-scale high resolution patterning of bio-microstructures is achieved using precise protein photolithography. The application of these micropatterned structures as cellular substrate for the successful spatial guidance of fetal neural stems cells using well-defined silk fibroin light chain ...[ Learn more ]

Inkjet Printing of Regenerated Silk Fibroin: From Printable Forms to Printable Functions
Cells “spin” a mineralized spiderweb: BMP-2-loaded silk material is inkjet-printed into a spiderweb pattern on a Petri dish and seeded with mesenchymal stem cells (MSCs). Upon culture in osteogenic media, the osteo-inductive print topographically controls the differentiation of MSCs, resulting ...[ Learn more ]

All-water-based electron-beam lithography using silk as a resist
The use of silk as a natural and biofunctional resist for electron-beam lithography is presented. The process is entirely water-based, starting with the silk aqueous solution and ending with simple development of the exposed silk film in water. Because of its polymorphic crystalline structure, si...[ Learn more ]
