Silk Inverse Opals: Modulation of Multiscale 3D Lattices through Conformational Control: Painting Silk Inverse Opals with Water and Light (Adv. Mater. 38/2017)

In article number 1702769, Fiorenzo G. Omenetto and co-workers demonstrate a new kind of amorphous silk-based large-scale inverse opal by an approach that effectively combines bottom-up and top-down techniques to obtain control on the nanoscale, microscale, and macroscale, resulting in a controllable photonic lattice and a resulting palette spanning almost the entire visible range. Thus, sub-millimeter, multispectral patterns are defined.
