Is nanotechnology a means to an end?

Sustainability

Nanotechnology

Nanotechnology is derived from the combination of two words Nano and Technology. Nano means very small or miniature. So, it is the technology in miniature form. It (sometimes shortened to "nanotech") is the study of manipulating matter on an atomicandmolecular scaleOne nanometer (nm) is one billionth, or 109, of a meter. It deals with structures sized between 1to 100 nanometer in at least one dimension, and involves developing materials or devices within that size.What is nanotechnology?

At the nanoscale, the physical, chemical, and biological properties of materials differ in fundamental and valuable ways from the properties of individual atoms and molecules or bulk matter.Nanotechnology R&D is directed toward understanding and creating improved materials, devices, and systems that exploit these new properties. What happens at the nanoscale?

The main tools used in nanotechnology are three main microscopes:-

Atomic Force Microscope (AFM)

Scanning Tunneling Microscope (STM)

Transmission Electron Microscope (TEM) Tools In Nanotechnology:-

7There are three main tools used in the field of nanotechnology: transmission electron microscopes, atomic force microscopes, and scanning electron microscopes.

Creates 3D image.Laser light from a solid state diode is reflected off the back of the cantilever .It detects cantilever deflections
