主　　题：ZnSe quantum dots two-photon absorption biological imaging zebrafish 

摘      要：This study is to report a ZnSe quantum dot with a large two-photon absorption cross section and good biocompatibility,which can be used in *** emission at 410 nm is observed in the quantum dot under 760-nm laser *** biocompatible quantum dots exhibit a two-photon cross-section of 9.1×105 GM(1 GM=10-50 cm4·s/photon).Two-photon excited laser scanning microscopic images show that cells co-cultured with ZnSe quantum dots are found in the blue channel at a fluorescence intensity that is 14.5 times that of control cells not cocultured with quantum *** incubating zebrafish larvae with ZnSe quantum dots for 24 h,the fluorescence intensity of the yolk sac stimulated by ultraviolet light is 2.9 times that of the control *** proposed material shows a great potential application in biological imaging.
