manipulation of Matter on an atomic or molecular scale - Nanotechnology

What is Nanotechnology?

Nanotechnology involves the manipulation of matter on an atomic or molecular scale, typically within the range of 1 to 100 nanometers. This field of science and engineering focuses on designing and creating structures, devices, and systems by controlling shape and size at the nanometer scale. The unique physical, chemical, and biological properties of materials at this scale enable novel applications across various sectors.

How is Matter Manipulated at the Nanoscopic Scale?

At the nanoscopic scale, scientists employ techniques like scanning tunneling microscopy (STM) and atomic force microscopy (AFM) to visualize and manipulate individual atoms and molecules. These tools allow for precise positioning and modification of atoms, enabling the construction of nanoscale structures with specific properties. Chemical vapor deposition and molecular self-assembly are other common methods used to synthesize and organize materials at the nanoscale.

What are the Applications of Nanotechnology?

The applications of nanotechnology are vast and diverse, impacting numerous fields:

Medicine: Nanotechnology enables targeted drug delivery systems, improved imaging techniques, and the development of biocompatible materials for implants.
