Nanotechnologies
The utilisation of the structure and properties of nanoparticles is a revolutionary and state-of-the-art technology that can be applied in a wide array of fields and human activities.
The term 'nanotechnology' generally refers to a technical field that explores the creation and use of nanometric technologies (usually approx. 1-100 nm), i.e. 10-9 m (a trillionth of meter), which equals about one thousandth of a human hair width.
Nanotechnology currently includes four principal areas: nanoelectronics, nanomaterials, molecular nanotechnology and microscopes with nanometer resolution.
Nanotechnology is basically a science of nanometer-sized materials.
Nanomaterials
(nanostructured materials) include those materials the new properties of which are defined by characteristic features (particles, clusters, hollows) measuring, at least in two dimensions, between 1 and 100 nm.
