Abstract

From silk to spheres: A large-scale synthesis of water-soluble nitrogen-doped polymer-like carbonaceous nanospheres with a uniform size of ca. 70 nm, through a simple and green hydrothermal process employing cocoon silk in water, has been developed. The resultant nanospheres show excellent photoluminescent properties, exhibit low toxicity, and are biocompatible for in vivo imaging.
