7 Amazing Everyday Examples Of Nanotechnology In Action

Nanotechnology essentially means controlling matter on a tiny scale, at the atomic and molecular level. This sounds truly sci-fi, but can, in fact, be put to some very ordinary uses in surprisingly everyday products. In this article, we’ll explore common products that make use of nanotechnology – but first, let’s get a quick overview of the amazing world of nanotechnology... What is nanotechnology? Nanotechnology is about looking at the world on such a tiny scale that we can not only see the atoms that make up everything around us (including ourselves), but we can manipulate and move those atoms around to create new things. Think of nanotechnology, then, as being a bit like construction … only on a tiny scale. And I do mean tiny. The nanoscale is 1,000 times smaller than the microscopic level and a billion times smaller than the typical world of meters that we’re used to measuring things in. (Nano literally means one-billionth.) If you took a human hair, for instance, it would measure approximately 100,000 nanometers wide. That’s the sort of scale we’re dealing with at a nano level. That’s all very cool, I hear you say, but how does understanding this nanoscopic world impact (if you’ll excuse the pun) the world at large? For one thing, when we zoom in and look at materials on an atomic level, we sometimes find they behave quite differently and have completely different properties at the atomic level. As a simple example, silk feels incredibly soft and delicate to the touch, but if you look at it at a nano-level, you’ll see it’s made up of molecules aligned in cross-links, and this is what makes silk so strong. We can then use knowledge like this to manipulate other materials at a nano level, to create super-strong, state-of-the-art materials like Kevlar. This is where the technology bit of nanotechnology comes in – using our knowledge of materials at a nano-level to create exciting new solutions and products. Everyday products that use nanotechnologyNanotechnology may seem like something out of the future, but in fact, many everyday products are already made using nanotechnology. Take these seven common products, for instance:Nanoparticles have been added to sunscreens for years to make them more effective. Two particular types of nanoparticles commonly added to sunscreen are titanium dioxide and zinc oxide. These tiny particles are not only highly effective at blocking UV radiation, they also feel lighter on the skin, which is why modern sunscreens are nowhere near as thick and gloopy as the sunscreens we were slathered in as kids. When used in textiles, nanoparticles of silica can help to create fabrics that repel water and other liquids. Silica can be added to fabrics either by being incorporated into the fabric’s weave or sprayed onto the surface of the fabric to create a waterproof or stainproof coating.
