What is Nanotechnology in simple words

What is Nanotechnology in simple words

The emergence of Nanotechnology is one of the greatest events humanity is experiencing. Just as electricity quickly integrated into all areas of our lives, nanotechnology is doing the same. The significant advancements in artificial intelligence, smartphones, energy generation, the creation of new materials, and even the possibility of becoming healthier are just some of the achievements of nanotechnology. Every day brings something new.  


What is Nanotechnology

If we search the internet for the word "nanotechnology," we will find the following definition: Nanotechnology involves the study, design, creation, synthesis, manipulation, and application of materials through the control of matter at the nanoscale, and the exploitation of phenomena and properties of matter at the nanoscale. In this context, materials are understood as anything tangible and visible: from a piece of metal, a chemical compound, to our own body. As for the nanoscale... Let's divide a meter into a thousand equal parts to get a millimeter, which is one-thousandth of a meter, something very small; now divide that millimeter into a million equal parts, and you will have one-millionth of a millimeter, which is a nanometer. In relation to a meter, it would be one-billionth of it. A red blood cell, the blood cell responsible for carrying oxygen throughout the body, measures between 6,000 and 8,000 nanometers. That means: if we multiply a nanometer by a million to make it just a millimeter, and use that same conversion for the blood cell, the red blood cell would now have a diameter of 6 to 8 meters.

What happens to matter when processed with nanotechnology

The nanoscale is not just about size; when matter is at the nanoscale, its physicochemical and quantum properties change. For example, gold melts at 1064°C, but when it is in the form of nanoparticles, that temperature would be only 800°C. Another example is aluminum, a metal that is not attracted to magnets, but if that material, aluminum, is reduced to the nanoscale, it gains that property and can be attracted by magnets.


How changes in matter are explained with nanotechnology

Let's consider the importance of nanometric dimensions: imagine a nanoparticle, in this case, a copper nanosphere of just 5 nanometers, and apply the formulas for area and volume; according to the density, we calculate the number of copper atoms that make up the nanosphere; now, using the formula employed by scientists, we calculate how many of those copper atoms are on the surface of the sphere, which in this example would be 22.61%. If we do the same calculation with a copper sphere 20 cm in diameter, the percentage of surface atoms would be only 0.00000057%. In other words: the smaller the particle, the higher the percentage of surface atoms, and the higher the percentage, the more quantum properties and physicochemical changes appear.


What is the future of nanotechnology

These changes have allowed not only new properties to emerge in materials but also for many of them, such as strength, hardness, conductivity, and others, to increase and become more efficient. We are seeing and experiencing this. Nanotechnology is truly the industrial revolution of the 21st century, where only imagination is the limit. For example, something that not long ago would have been considered "crazy"... Can you imagine recharging your smartphone with a USB terminal coming out of your shirt? The secret would be that your shirt is made with nanofibers capable of converting sunlight into the energy needed to recharge your smartphone. That is now possible.  


What benefits does nanotechnology bring to health

In the field of health, the potential of nanotechnology is so broad that it is encompassed in the term Nanomedicine, which is defined as the application of the principles and techniques of nanoscience in the medical field, currently covering five areas: diagnosis, imaging, therapy, regeneration, and vaccines. In practical terms, this means:
  • More efficient disease prevention.
  • Earlier diagnoses.
  • More effective treatments.
Nanotechnology has already entered the pharmacy with the objective of: lower doses, greater efficacy, fewer side effects, and fewer limitations due to barriers that previously prevented reaching organs and tissues like those of the central nervous system. This is now a reality. Thanks to nanotechnology, there are several oncological products that can attack a tumor more directly and efficiently, with less damage to healthy tissues, reaching places like the brain where they could not before. Nanotechnology is also present in other therapeutic areas. This reality is not limited to complex pharmaceutical products; we also find it in the field of dietary supplements. Punicic Acid Omega 5 (What are the benefits of Omega 5) is a powerful natural antioxidant extracted from pomegranate seed oil. When this oil is processed with nanotechnology to convert it into a nanoemulsion, it becomes an antioxidant 100 times more potent than natural oil and can cross the blood-brain barrier, providing antioxidant protection to the brain and other organs of the central nervous system. This potent nanoformulated antioxidant is available under the name GranaGard® Omega 5. (Omega 5 sales page on Another supplement transformed by nanotechnology is Omega 3, (10 Omega 3 body systems organs benefits) which now also has its beneficial effects multiplied.

We are fortunate; nanotechnology has come to benefit our health, environment, communications, transportation, food production… Nanotechnology is already in our lives.
