Multifunctional nanoparticles can include two or more different populations of nanocrystals that impart a combination of properties arising from the constituent populations in a single, multifunctional nanoparticle.

Multifunctional nanoparticles

A method of making a nanocrystal includes slowly infusing a M-containing compound and a X donor into a mixture including a nanocrystal core, thereby forming an overcoating including M and X on the core.

Semiconductor nanocrystals

A method of preparing a coated nanoparticle can include decomposing a compound to produce a nanoparticle, oxidizing the nanoparticle to produce an oxidized nanoparticle, and coating the oxidized nanoparticle with a zwitterionic ligand to produce the coated nanoparticle. The coated nanoparticle or the nanoparticle can be used in magnetic resonance imaging.
