micro and nanomanufacturing

 

Silk can be nanopatterned with features smaller than 20 nm. This allows manufacturing of structures  such as (among others) holographic gratings, phase masks, beam diffusers and photonic crystals out of a pure protein film. The properties of silk allow these devices to be "biologically activated" offering new opportunities for sensing and biophotonic components in a true marriage of technical form and biological function.
