Researchers at the Tufts University School of Engineering and Boston University have developed metamaterial structures patterned on implantable silk substrates, which could be helpful in the development of biosensors and biodetectors.

Metamaterials can be used to destroy cancerous tissue using heat.

The researchers sprayed gold-based metamaterial on silk films to create capsule-like cylinders, which contain 10,000 metamaterial resonators per 1cm² sample.

The metamaterials retained their novel resonance properties when implanted into muscle, the researches added.

Fiorenzo Omenetto, who led the research, said that the approach offered great promise in situ bio-sensing with implanted medical devices and transmitting medical information from within the human body.

“Imagine the benefits of monitoring the rate of drug delivery from a drug-eluting cardiac stent, making a perfect absorber that can be implanted to attack diseased tissue by heat,” Omenetto added.
