Everything You Need to Know About Nanotechnology


Nanotechnology is the study and application of extremely small things and can be used across all the other sciences. From physics to biology to chemistry, nanotechnology is helping researchers find new and improved ways to create, study, control, and manipulate matter at the atomic and molecular levels.

What Is Nanotechnology?

The National Nanotechnology Initiative (NNI) defines nanotechnology as “the understanding and control of matter at dimensions of roughly 1 to 100 nanometers (nm), where unique phenomena enable novel applications.” A nanometer is one-billionth of a metre—think about how small that is! To give you some perspective, here are a few everyday examples that illustrate just how tiny nanoparticles can be:

• There are about 25,400,000 nanometers in an inch

• There are about 10,000,000 nanometers in the width of a human hair

• There are about 100,000,000 nanometers in the diameter of a red blood cell

Because they’re so small, nanoparticles can exhibit unique chemical and physical properties that differ from both the bulk material they’re made from and the individual atoms or molecules that make them up. This is what gives them such great potential for a wide range of applications across many different industries.

How Is Nanotechnology Used?

Nanotechnology is being used or studied for use in many different fields, including:

1. Medicine

Nanoparticles are being developed for use in cancer treatments, as well as for delivering drugs directly to specific cells in the body (known as targeted drug delivery). Nanoparticles are also being used in medical devices, such as artificial joints and implants, and diagnostic tools, such as DNA sequencing devices.

2. Energy

Nanomaterials are being explored for use in solar energy conversion, fuel cells, and lithium-ion batteries.

3. Food and agriculture

Nanotechnology is being used to create food packaging that can extend shelf life by preventing oxygen or moisture from entering the food. Nanoencapsulation—the process of enclosing something inside a nanoparticle—is also being used to deliver nutrients directly to plants and improve crop yields.

4. Water purification

Nano filters made from nanoparticles of titanium dioxide or zerovalent iron can remove contaminants from water more effectively than traditional methods.

5. Manufacturing

Nanotechnology is being used to create stronger, lighter materials for use in everything from planes and automobiles to sporting goods and construction equipment. Nanoparticles are also being used to create self-cleaning, stain-resistant surfaces and to improve the efficiency of manufacturing processes.

The Future of Nanotechnology

The potential applications of nanotechnology are virtually limitless. In the future, nanotechnology could be used to create self-cleaning surfaces, improved food and water supplies, cleaner energy sources, and more efficient medical treatments.

Nanotechnology could also lead to the development of new materials with unique properties, such as clothes that can regulate body temperature or windows that can block out heat or UV rays. Ultimately, nanotechnology could change the world as we know it, making everyday life easier and improving the quality of life for people around the globe.


Nanotechnology is a rapidly growing field with immense potential, and it’s important to stay up-to-date on the latest advancements.
