It is used to convey vaccines, drugs, enzymes, or other substances to organs

Polymer miscelles
Nano-sized particle (~10 to ~100 nm) composed of block or graft copolymers, typically having a so-called core-shell structure. The core contains the drugs, while the shell interacts with the solvent making the nanoparticle stable in the liquid
Especially useful for poorly water-soluble pharmaceutical active ingredients. The stability of the drug is also increased. Undesirable side effects are lessened, as contact of the drug with enzymes in biological fluids is minimized

Dendrimer
A macromolecule with highly branched 3D structure, consisting of three main components: core, branches and end groups, and providing a high degree of surface functionality and versatility. It originates from the Greek dendron, meaning “tree”
It is small enough to enter cells carrying the drug. It has a great potential in drug nanoformulations for melanoma therapy owing to advantages, such as thermodynamic stability, high solubility in water, the controllable size (usually 1 to over 10 nm), morphology and functional groups on the surface, and uniform size distribution
