Silk protein,from Bombyx mori,is environmentally friendly and highly biocompatible.UCNPs(upconversion nanoparticles)are favored in medicine and environmental monitoring due to their good biocompatibility,excellent stabili-ty,and high fluorescence intensity.In order to further promote the diversified applications of silk fiber,we prepared silk fi-ber emitting fluorescence under irradiation of near-infrared laser by feeding UCNPs to silkworms.The results indicated that the silk fiber from the bred silkworm gave off strong green fluorescence when exposed to a 980 nm laser.Meanwhile,the fluorescent silk fiber exhibited good mechanical properties,and could be used for a sensitive detection to the oxidant in an environment with polydopamine.The research in this paper provides a new idea for the development of new fluores-cent silk materials.
