Metamaterial Silk Composites at Terahertz Frequencies
Fabrication and characterization of the first large area metamaterial structures patterned on free-standing biocompatible silk substrates is reported. Strong resonance responses at terahertz frequencies are shown, providing a promising path towards the development a new class of metamaterial-insp...[ Learn more ]

Silk-Based Conformal, Adhesive, Edible Food Sensors
An array of passive Au antennae fabricated on an all-protein-based silk substrate were conformally transferred and adhered to the surface of an egg. The process allows for intimate contact of micro- and nanostructures that can probe their surrounding environment, and accordingly provides the oppo...[ Learn more ]

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 ]
