Nanoindentation is a precise measuring method for determining the mechanical properties of materials on a micrometre to nanometre scale. A very small tip, usually made of diamond, is pressed into the surface of a material with controlled force. Important parameters such as hardness and modulus of elasticity can be derived from the penetration depth and the applied load. Nanoindentation is frequently used in materials research, particularly for thin layers, nanomaterials and biological samples.
