What is the field that involves manipulating atoms and molecules at the nanometer scale called?

The field that involves manipulating atoms and molecules at the nanometer scale is known as nanotechnology. This discipline focuses on designing, producing, and using structures, devices, and systems by controlling shape and size at the nanometer scale, which is typically between 1 to 100 nanometers.

Nanotechnology encompasses a broad range of applications, including materials science, medicine, electronics, energy production, and environmental protection. The manipulation of materials at such a small scale allows for unique properties and behaviors, leading to advancements in various fields.

In contrast, biotechnology pertains to the use of biological systems or living organisms to develop products or processes, typically on a larger scale than nanotechnology. Microbiology, on the other hand, is the study of microscopic organisms, such as bacteria and viruses, and does not specifically involve manipulation at the atomic or molecular level. Pharmacology is the study of drugs and their effects on the body, which may involve molecular interactions but is not primarily focused on the nanometer scale.
