What is NanotechnologyWhat is Nanotechnology

the study of the controlling of matter on an the study of the controlling of matter on an atomic and molecular scale. Generally atomic and molecular scale. Generally nanotechnology deals with structures nanotechnology deals with structures sized between 1 to 100 nanometer in at sized between 1 to 100 nanometer in at least one dimension, and involves least one dimension, and involves developing or modifying materials or developing or modifying materials or devices within that size. devices within that size.
