Metal molecules are sub-nanometer clusters of typically 3 to 10 atoms of elements such as Ag, Cu & Ni, with properties defined by quantum rather than classical mechanics.

Quantum confinement of electrons, absence of crystalline form and the presence of a band gap, results in new and different properties from bulk materials and conventional nanomaterials.

Metal Molecules have size dependent properties, based on the number of atoms per molecule, therefore properties can be controlled and tuned to mimic other bulk materials including precious metal nanoparticles or conventional semiconductors but without the problems of hole and electron recombination, poisoning or stability associated with bulk and nano materials.
