Abstract
A method of forming a metal colloid comprising a plurality of particles, each particle comprising a core of a metal, is described. The method comprises the steps of providing an organometallic precursor comprising the metal, combining the organometallic precursor and a solvent, which comprises water molecules, heating the combination of organometallic precursor and solvent so that the organometallic precursor decomposes to form a solution including the metal colloid and by-products, and removing the by-products to provide the metal colloid.
