Programmable Bulk Optical Materials from Silk

In recent years, natural silk has attracted increasing attention for its potential as a tough, biologically friendly medium for fashioning nano – to microscale optical devices. Now, engineers at Tufts University, USA, led by OSA Fellow Fiorenzo Omenetto, have taken another step on the silk road: they’ve created a process for building macroscopic, bulk materials from silk that can embed interesting functionalities – including optically enabled ones.
