Methods for controlling surface functionality of metal oxide nanoparticles, nanoparticles having controlled surface functionality, and uses thereof are described herein. Methods for controlling the surface functionality of a metal oxide nanoparticle are can include attaching a ligand to a metal oxide nanoparticle, where the ligand can include a functional portion that is capable of forming an irreversible bond with an object at a site that is complementary to the functional portion without reacting with other reactive sites that may be present. Moreover, metal oxide nanoparticles having versatile ligands can include an anchoring portion that binds to the surface of the metal oxide nanoparticle and a functional portion that is capable of forming an irreversible bond with an object at a site that is complementary to the functional portion without reacting with other reactive sites that may be present. Uses thereof can include cancer detection, electronics, cosmetics, cellular delivery carriers, magnetic storage media, drug delivery carriers, nanocomposite formation for improved mechanical properties, and the like.
