Biosensor based on spider silk

Caption

Researchers used the light-guiding properties of spider silk to develop a sensor that can detect and measure sugar concentrations based on refractive index. The sensor is made from silk from the giant wood spider Nephila pilipes, which was enveloped in a biocompatible photocurable resin and then functionalized with a biocompatible nano-layer of gold.
