Overview
The science of working with matter at the atomic and molecular level is known as nanotechnology. It is a revolution rather than merely a scientific achievement. By working at scales between 1 and 100 nanometers. Nanotechnology enables us to develop materials and technologies with unique characteristics. Medicine, energy, electronics, software development, machine learning, and the environment are all being revolutionized by these developments. This blog explores the revolutionary promise, real-world uses, and challenges of nanotechnology.
Nanotechnology : What is it?
We must first comprehend the scale at which nanotechnology functions in order to fully grasp its significance. One billionth of a meter is called a nanometer. For comparison, the thickness of a human hair is about 80,000 nanometers. Materials exhibit characteristics at this scale that are not seen in their macroscopic counterparts, such as greater strength, reduced weight, or improved chemical reactivity. These traits have opened the door for innovations in a wide range of industries, such as software and artificial intelligence.
