ABSTRACT The word Nanoscience refers to the study, manipulation and engineering of matter, particles and structures on the nanometer scale (one millionth of a millimeter, the scale of atoms and molecules). Important properties of materials, such as the electrical, optical, thermal and mechanical properties, are determined by the way molecules and atoms assemble on the nanoscale into larger structures. Moreover, in nanometer size structures these properties often different then on macroscale, because quantum mechanical effects become important Nanoscience and nanotechnology are interdisciplinary fields that involve the study and manipulation of matter at the nanoscale, typically at dimensions less than 100 nanometers. These fields have gained significant attention and importance due to the unique properties and phenomena that occur at the nanoscale, which differ from those at larger scales.
