What is Nanotechnology
the study of the controlling of matter on an
atomic and molecular scale. Generally
nanotechnology deals with structures
sized between 1 to 100 nanometer in at
least one dimension, and involves
developing or modifying materials or
devices within that size.
Nanotechnology
is already making today’s products:
