Nanomaterials

Definition

Nanomaterials are materials with structures on the nanoscale, typically ranging from 1 to 100 nanometers in size. Their unique properties, which differ significantly from those of bulk materials, make them increasingly important in specialized applications, particularly in cleaning techniques for art conservation and restoration. These materials can enhance cleaning efficiency and minimize damage to delicate surfaces by providing targeted interaction at the microscopic level.
