nanomaterials - wikipedia
a bulk material should have constant physical properties regardless of its size but at the nano-scale this is often not the case. size-dependent properties are observed such as quantum confinement in semiconductor particles surface plasmon resonance in some metal particles and superparamagnetism in magnetic materials.
