Natural carbon fibers

Silkworms can spin ingested graphene into strong, conductive reinforced silk, according to research published in the journal ACS Nano Lett. This quasi synthetic biomaterial could find applications in wearable electronics, biodegradable sensors, and medical implants, according to Prachi Patel writing in the ACS's flagship magazine C&EN. Yingying Zhang and her colleagues at Tsinghua University, China, simply fed the silkworms mulberry leaves sprayed with an aqueous solution of carbon nanotubes or graphene and collected the silk from the creatures' cocoons, as is done for conventional standard silk production.
