Abstract

A nanometer-sized particle comprises a core comprising at least one metal or metal alloy; and a monolayer chemically bonded to the core. The monolayer contains at least one reactive substituent which is coupled to a functional material such that the monolayer is chemically modified. A method of making a functionalized nanometer-sized particle comprises providing a nanometer-sized particle comprising a core which comprises at least one metal or metal alloy, and a monolayer adsorbed onto the core wherein the monolayer includes at least one reactive substituent; and coupling the nanometer-sized particle with a functional material such that the monolayer is chemically modified.
