The roots of nanotechnology reach back to 1959, when the visionary physicist Richard Feynman gave his famous lecture “There’s Plenty of Room at the Bottom.” He described a future in which technology could operate at atomic and molecular levels. The term nanotechnology itself, however, was only coined in 1974 by the Japanese researcher Norio Taniguchi, who referred to the controlled processing of matter at the nanoscale.
A major push for public awareness came in the 1980s, when Eric Drexler described the concept of molecular machines and factories in his book “Engines of Creation.” While some of his ideas remain controversial, they inspired generations of scientists. By the 1990s and early 2000s, nanotechnology had matured into a truly interdisciplinary field — with contributions from physics, chemistry, biology, and engineering alike.
What makes nanotechnology so exciting is that matter behaves differently at this level. Once you move below 100 nanometers, quantum effects become important, and materials can suddenly acquire properties that are absent at larger scales. Substances may become more chemically reactive, optically transparent, magnetically active, or electrically conductive.
A striking example is titanium dioxide. In conventional form it is used in wall paint, making surfaces appear brilliantly white. But as nanoparticles, titanium dioxide no longer reflects visible light, only ultraviolet radiation. It suddenly becomes transparent — a property that is put to use in sunscreens. The result: a cream that reliably blocks harmful UV rays while remaining invisible on the skin.
Nanomaterials come in a surprising variety of shapes. There are nanoparticles, which behave uniformly in all directions; nanotubes and nanowires, which are highly directional; thin films and sheets such as graphene; and even three-dimensional bulk materials with nanoscale pores and textures.
These structures exhibit superior performance compared to their larger counterparts. Surfaces can become self-cleaning, coatings can resist ultraviolet radiation, and new composites can be both lighter and stronger than traditional materials. It is this versatility that makes nanotechnology such a powerful driver of innovation.
Nanotechnology is often called an “enabling technology” because it empowers so many other fields. In energy, it paves the way for more efficient solar cells and advanced batteries. In medicine, it enables targeted therapies and diagnostic tools at the molecular level. In environmental science, it provides high-performance filters and water-repellent coatings. And in materials research, it delivers a new generation of lightweight, durable, and multifunctional substances.
Carbon nanotubes are a perfect example of this potential. They are stronger than steel, lighter than aluminum, and superb conductors of heat and electricity. Already they are found in sports equipment, electronics, and automotive components - and their future applications are likely to expand even further.
Nanotechnology is a true “enabling technology.” Its impact stretches across industries:
The carbon nanotube (CNT) is a superstar: incredibly light, stronger than steel, and excellent at conducting electricity. It’s already used in sports equipment, electronics, and even car manufacturing.
Yet, as with any powerful technology, nanotechnology comes with questions. Certain nanoparticles — for example titanium dioxide or zinc oxide in their nano form - may pose health or environmental risks under specific conditions. Some studies suggest possible toxicity, while others point to long-term uncertainties.
To ensure safe development, Europe has invested heavily in risk research and regulation. Initiatives such as the EU Observatory for Nanomaterials, national registers, and standardized testing are designed to provide transparency, enable monitoring, and guide responsible innovation.
Nanotechnology is undoubtedly one of the most promising fields of our time. It enables us to harness the smallest building blocks of matter for big solutions in energy, healthcare, materials science, and environmental protection. At the same time, it reminds us of the responsibility that comes with such power.
The challenge for the future is clear: to shape nanotechnology in a way that combines innovation with sustainability and safety. Europe, with its strong research base and growing awareness of environmental and health aspects, is well positioned to play a leading role.
