Claim:
1. A method of preparing polymer-functionalized particles, the method comprising: (a) introducing a sputtering gas into a particle source under ultra-high vacuum conditions; (b) ionizing the gas; (c) passing the ionized gas through a plasma region in the opening(s) between targets or through the targets to liberate atoms from the target, thereby yielding a gas comprising the liberated atoms; (d) condensing the gas comprising the liberated atoms to yield particles; (e) collecting the particles on a collection device that comprises a substrate and a polymeric functionalization coating disposed on the substrate, wherein the particles impinge upon, and form bonds with molecules of the functionalization coating; and (f) washing collected polymer-functionalized particles obtained in step (e), thereby removing the functionalized particles coated with polymer molecules of the polymeric functionalization coating from the substrate.
