A Brief History of Nanotechnology: Part 4 - The Early 2000s to the Present Day

Our last post explored the emergence of the field of nanotechnology as we know it in the 1980s and 1990s, including seminal developments by scientists such as Eric Drexler, Richard Smalley, and others.

Now we turn our attention towards the early 2000s, which proved to be an exciting time for nanotechnology. The field could now be explored and debated in greater depth. Drexler and Smalley, for instance, famously engaged in a public discussion about approaches to nanotechnology, with Drexler defending his idea of "universal assemblers" and Smalley offering objections.

Meanwhile, concerns about the broader implications of nanotechnology - a potentially very powerful but still relatively new field - were being raised and addressed with consideration given to both the potential benefits as well as risks involved. In 2003 congressional hearings on the societal implications of nanotechnology were raised and in 2004 the Royal Society and Royal Academy of Engineering published a report on the implications of nanotechnology and nanoscience, which you can read here.

Nanotechnology also began to appear more in more commercial settings during the 2000s, including the emergance of our technology and the launch of ion-mask on Hi-Tec shoes:

In the early part of the decade, titanium dioxide and zinc oxide nanoparticles were included in sunscreen and cosmetics, and carbon nanotubes were used to make textiles stain-resistant. By 2011 the Project on Emerging Nanotechnologies estimated that there were over 1300 nanotech products publicly available.

In our next and final post of the series, we'll take a closer look at what the future might hold for nanotechnology. If would like to read some of our early posts in this series you can through the links below:

A Brief History of Nanotechnology: Part 3 - The 80s & 90s

In our last post we looked at some very early developments in nanotechnology, including the possible impact that Richard Feynman's 1959 lecture "There's Plenty of Room at the Bottom" may have had on later advances in the field. It was certainly an influence on Eric Drexler, "the undisputed godfather of nanotechnology", who encountered Feynman's talk in 1979.

The 1980s saw the real emergence of nanotechnology as a field of study. The publication of Drexler's seminal book Engines of Creation: The Coming Era of Nanotechnology in 1986 marked an important milestone for the field. In the book, Drexler (unknowingly) appropriated and popularised the term "nanotechnology" itself, which had been initially defined in a slightly different context in 1974 by Tokyo Science University Professor Norio Taniguchi as "the processing of, separation, consolidation, and deformation of materials by one atom or by one molecule". In Engines of Creation, Drexler presented his idea of molecular manufacturing and the "molecular assembler": a "proposed device able to guide chemical reactions by positioning reactive molecules with atomic precision". Drexler's 1992 book Nanosystems: Molecular Machinery, Manufacturing, and Computation, published after completion of his PhD at MIT (he earned the first doctoral degree on the topic of molecular nanotechnology) continued to build on these ideas.

The 1980s also saw other important advances, including the invention of the scanning tunnelling microscope (STM) in 1981 and the discovery of fullerenes in 1985. The Scanning Tunnelling Microscope, developed by Gerd Binnig and Heinrich Roher at IBM Zurich Research Laboratory, allowed surfaces to be examined at the atomic level. In 1985, Harry Kroto, Richard Smalley and Robert Curl discovered fullerenes, sometimes called buckyballs - hollow molecules composed of carbon, which helped lead to the structural assignment of carbon nanotubes. These developments meant that "nanotechnology could develop through the scientific method rather than the conceptual and thus untestable visions of Drexler", and the field as we know it today - diverse and full of possibility - was born.

Next week we'll look at some of the debates and developments that have occurred in more recent years, and get a glimpse of where nanotechnology might be headed in the future.

P2i Presents: The Repellent Files

You may be wondering what the title means. Well, here at P2i we are often asked what other products our technology could be applied to. And this is a question that is regularly brought up by people who have witnessed our tissue demonstration as well:

So this got us thinking and the idea of The Repellent Files were born.

So what are The Repellent Files?

Each week we will upload a new video to YouTube of a different, normally water absorbent item that has been treated with our liquid repellent nano-coating to see how well it copes when subjected to water or other liquids.

In our first file posted yesterday, we investigated whether a teabag, coated with our nanotechnology, could keep the water clear once boiling hot water was poured over it. To ensure it was an even test, we had a regular teabag available as well.

Want to know what happened? Well, have a watch of the video below and you can see the result for yourself:

The Verdict:

Thumbs Up! Although it is not very good if you want a cup of tea, but the test shows that our coating can stop a teabag acting as it should by successfully repelling the water around it.

If you have any suggestions for items that can be put to the test, do let us know. You can also follow us on Facebook, Twitter and YouTube where we will be posting the next file.

A Brief History of Nanotechnology: Part 2 - Early Developments

In our first post, we looked at some surprisingly early examples of nanotechnology at work. However, the field is generally considered to be a very modern one, and most major early developments occurred within the latter half of the 20th century.
The history of nanotechnology is often traced to a very specific moment of inception: the 29th of December, 1959, when physicist Richard Feynman delivered an after-dinner lecture called "There's Plenty of Room at the Bottom" during a meeting of the American Physical Society at the California Institute of Technology.

Feynman's lecture predated the use of the term "nanotechnology" to describe the field of study as we now know it, but many of the ideas he explored and the questions he asked are still highly relevant.

Feynman wondered "why cannot we write the entire 24 volumes of the Encyclopaedia Britannica on the head of a pin?" and spoke of the possibility of building machines on a minute scale by "manoeuvring things atom by atom".

‘There’s Plenty of Room at the Bottom’ writes Dr. K. Eric Drexler, whose own work in the 1970s and 80s did much to advance the field, "was a comparatively casual effort - an after-dinner speech at a conference - yet in it he presented a bold and enduring vision of a technological journey leading toward the atomic scale and toward the ultimate boundaries set by physical law. The world has travelled far toward what Feynman saw, and has far still to go."

It's hard to measure the exact impact that Feynman's talk had on the emergence of nanotechnology, of course, but, as Drexler points out, "Feynman was the first to outline a world of technologies that would work and build at the ultimate, atomic scale".

The term "nanotechnology" itself wasn't coined until 1974, when Tokyo Science University Professor Norio Taniguchi defined it: "'Nano-technology' mainly consists of the processing of, separation, consolidation, and deformation of materials by one atom or by one molecule’.' Taniguchi used the term "to describe semiconductor processes such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer. The ideas contained in this definition were further explored and developed by Drexler in the late 70s and 1980s, culminating in the release of his book Engines of Creation: The Coming Era of Nanotechnology in 1986, which "is considered the first book on the topic of nanotechnology".

In next weeks post we will take a closer look at these ideas and how they developed.

A Brief History of Nanotechnology: Part 1 - Roots

In this series we are going to take a closer look at the history of nanotechnology, from early findings through to the present day and what developments nanotechnology can bring for the future.

To begin we are going to explore the beginnings of nanotechnology.

Most people consider nanotechnology to be a modern field of science. Primary development occurred in the 1980s and 1990s, and it continues to evolve. Its history is usually traced as far back as Richard Feynman's famous 1959 lecture "There's Plenty of Room at the Bottom". Feynman did not specifically name nanotechnology, but his talk "inspired the conceptual beginnings of the field decades later”.

However, as a recent article in the Guardian suggests, the field may actually have roots that extend much further back - all the way into the ancient world. "Artisans from the past also controlled matter at the tiniest scales," writes the article's author, Rosamund Daw. "By modern-day standards, they were working in a branch of nanotechnology called nanocomposites. These are bulk materials in which nanoscale particles are mixed to improve the properties of the overall or composite material."

One example of this is the Lycurgus cup, a Roman glass cage cup containing nanoparticles that make the glass look red when light shines through it but green when viewed in reflected light. Another is Maya Blue, a bright azure pigment discovered in the Mayan city of Chichen Itz which is particularly resistant to wear and contains clay with nanopores into which indigo dye was combined chemically to create an environmentally-stable pigment. And in 2006 researchers in Germany revealed that they had discovered nanowires and carbon nanotubes in a Damascus steel sabre from the 17th century.

The artisans who crafted these objects and materials may not exactly have been nanotechnologists by modern standards, but it's impressive to see how far back the history of this modern technology can be traced. Moreover, the discoveries that today's scientists have made as a result of looking at these very old objects may actually help advance the field. "Some of these studies are providing pointers for new nanotechnology research," writes Daw. Based on a study of the properties of the Lycurgus cup, for example, "researchers have developed thin nanocomposite films containing gold nanoparicles which can reflect infra-red while still transmitting light. These films could be used to coat windows in hot countries to reflect heat away while allow light through the glass, thus reducing the need for air conditioning." So the history of nanotechnology is informing its future.

In our next post we will take a look at the early stages of nanotechnology development...
