Preparation of C-ZIF-8 composite nanoparticles

This paper presents a method for preparing carbon nanodots@ZIF-8 (C-dots@ZIF-8) composite nanoparticles at room tempera-ture. C-dots@ZIF-8 core-shell nanostructures with adjustable-size diamond dodecahedron structure have orange-red fluorescence and pH responses. It can be used as a potential synergistic pH response anti-cancer drug delivery and biological cells fluor-escent imaging carrier. So it is further applied in the field of biomedicine.
