Method for making silk inverse opal structure
Method for making silk inverse opal structureThe present invention relates to silk-based engineering of structural colors and encompasses the recognition that photonic crystals made from silk fibroin can be used to enhance a wide array of light-induced phenomena. Among other things, the present application provides evidence that silk-based photonic...

Silk Fibroin as a Photoresist in Lithography
Tufts University investigators have developed a lithography resist that eliminates minimizes the use of harsh chemicals without sacrificing resolution. Optical-grade silk fibroin aqueous solution obtained from the cocoons of the Bombyx mori caterpillar is placed on a substrate and spin-coated to form a silk film. Competitive AdvantagesEliminates special...
