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.

The present invention includes a method for preparing a nanoparticle filled nanocomposite material, the method including the steps of providing a plurality of nanoparticles. attaching a first layer of organic ligand to the nanoparticle via a phosphate or phosphonate linkage, covalently attaching a second layer of matrix compatible polymer to said first layer of organic ligand to produce modified nanoparticles, providing a polymer matrix and dispersing the modified nanoparticles in the polymer matrix, wherein the dispersement of the modified nanoparticles into the polymer matrix results in a nanocomposite material, and wherein the modified nanoparticles are modified such that the first layer is proximal to the nanoparticle and the second layer is distal to the nanoparticle. Also within the scope of the invention are modified nanoparticles, alternative nanocomposite materials and methods of making the same.
