Nanosized systems are important in drug delivery. Such nanosized systems include liposomes, nanocrystals, micelles, colloidal particles, quantum dots, and dendrimers. Dendrimers are class of synthetic macromolecules with highly branched, monodispersed, circular, and symmetrical architecture that are used as carrier molecules in drug delivery.
