To be able to further expand an application field of nanoparticles comprising a silica shell and to make them available for various purposes. Skeleton nanoparticles 1 are nanoparticles that have an outer diameter R ranging from 30 nm to 300 nm and that comprise silica shells 1a. The silica shell 1a has a shape of a cubic frame. The cubic frame is hollow inside and pores are formed between quadrilateral silica frames on respective faces of the cubic frame. |
