If the atom in question is in a small particle on the surface of a piece of silicon, the result is what is known as a surface plasmon.

ECONOMIST: Solar energy

Half of the atoms in a five-nanometre particle are on its surface, which can make it many times more toxic than expected by weight alone.

ECONOMIST: The risk in nanotechnology

Any particle with a target molecule on its surface will stick to the spin valve.
