The present invention is related to a targeted type shell for drug delivery system. The object of the present invention is to provide the targeted type shell for DDS, which comprises a carbosilane dendrimer containing a silole produced by which is formed by utilizing the reaction between thiol group and alkyl halide, and a targeted protein containing a labeled proteins such as green fluorescent protein with a target recognition site. The shell may incorporate compounds having a variety of molecular weight and biopolymers, and selectively deliver them into targeted cells.
