Provided are methods of controlling the shape and surface chemistry of nanoparticles, particularly ferrite nanoparticles. Methods for preparing non-spherical ferrite nanoparticles, including nanocubes, nanobars, nanoplates, and nanoflowers, are described. Also provided are methods of functionalizing the surface of metal and metal oxide particles. The surface functionalization methods do not require the use of chemical linkers and/or additional reagents, and permit the facile conjugation of a range of molecules, including bioactive agents, to the surface of particles.
