Dendrimers are highly branched polymers with a three-dimensional structure. They are characterized by expansive functional groups on their surface, which can be tailored to interact with specific molecules or to be used in a variety of applications. Dendrimers have attracted much attention in drug delivery (e.g., for protein drug delivery service), imaging, and materials science due to their unique structure, high monodispersity, and tunable properties. They are frequently used as nanocarriers to deliver drugs or imaging agents to specific targets in the body, as well as in the development of advanced materials with unique properties.
