Hello and welcome to this journal article on nanotechnology. In this article, we will explore the fascinating and rapidly expanding field of nanotechnology. From its humble beginnings to its current cutting-edge applications, we will take a deep dive into the world of the minuscule. So, without further ado, let’s get started!
What is Nanotechnology?
Nanotechnology is the science, engineering, and application of materials and devices with structures smaller than 100 nanometers. A nanometer is one billionth of a meter, which is approximately 10,000 times smaller than the width of a human hair! At this scale, the properties of materials can differ significantly from their bulk counterparts, leading to unique characteristics and applications.
Nanotechnology has been around for centuries in the form of naturally occurring nanomaterials such as proteins, viruses, and DNA. However, it was only in the 1980s that scientists began to develop the tools and techniques to manipulate and engineer materials on the nanoscale.
Today, nanotechnology has a wide range of applications in various fields such as electronics, medicine, energy, and materials science. Let’s take a closer look at some of the exciting developments in nanotechnology.
