A couple of weeks ago whilst writing about nanotechnology and the associated risk involved in such engineering techniques I mentioned Nanoart.  This week I would like to expand and to present a gallery of examples.

To quote Cris Orfescu, founder of Nanoart 21, “NanoArt is a new art discipline at the art-science-technology intersections. It features nanolandscapes (molecular and atomic landscapes which are natural structures of matter at molecular and atomic scales) and nanosculptures (structures created by scientists and artists by manipulating matter at molecular and atomic scales using chemical and physical processes). These structures are visualized with powerful research tools like scanning electron microscopes and atomic force microscopes and their scientific images are captured and further processed by using different artistic techniques to convert them into artworks showcased for large audiences.”

One of the issues raised during discussion in my previous posts was about the usefulness and point of such artistic expression, so here I quote the NanoArt 21 website:

“The purpose is to promote  NanoArt worldwide as a reflection of a technological movement… a more appealing and effective way to communicate with the general public and to inform people about the new technologies of the 21st Century. NanoArt is aimed to raise the public awareness of Nanotechnology and its impact on our lives”.

There are several organizations that promote this form of expression and at least one international competition that offers cash prizes for the best examples (NanoArt 21 have an international competition). The German Centre for Research and Innovation hosted an exhibition of their collection in New York in 2011 and the number of artist/scientists involved seems to be growing.

The following gallery should give you an idea of this particular art form. Also take a look at the Nanobama here. The image is of nanotubes made in the shape of President Obama’s face, similar in style to the playboy above.

You can find many other examples online. Do you like them? I personally like the 3D effect. It seems more accentuated because the images are created by electrons (electrically charged particles) rather than photons (particles of light). The electrons penetrate deeper into the structure creating images with more depth.

Technology and the future of work

Technology is always changing and advancing the way we live our lives, unless you are a luddite and live in an Amish community that is! Some people oppose technological change, and I respect them for that, but personally I embrace it – techie all the way!

Technology is likely to improve the way we do business significantly in the near future, but how? In this article I am going to write about some of the latest and greatest technology which is going to revolutionise the way we work!

Portable Laser Keyboards

Okay, so you may be thinking that we already have keyboards that are pretty portable, you can get role up ones that you can take almost anywhere. The problem with these is of course, they do take up space, and often they cannot connect to your smartphone or tablet.

The future solution to this problem is already here: The Magic Cube. The Magic Cube is a super portable wireless laser keyboard, which has been developed by a company called Celluon. It is basically a little box which can project a laser keyboard onto any flat surfaces, and then works out what you are typing by where your fingers break the lasers.

This is no ordinary keyboard though, it can connect via Bluetooth to most smartphones, laptops, tablets and desktops, so wherever you are, no matter what your device, if you have your Magic Cube, you have a keyboard!

Hand Motion Technology

In the very near future, we will be able to control screens using our hands, and not by touching the screen (that technology already exists) but by simply waving a hand in the air.

The 2002 film Minority Report featured futuristic hand motion technology where detectives could push images off to the side and bring up more content just by waving their hands in the air. This was in the movie, because the film makers heard that the technology was being developed.

Better Integration

In the future we are likely to see much better integration of all technologies. Mainly thanks to the likes of cloud computing and improvements in wireless technology, it should become easier and easier to transfer files from device to to device.

Apps

Smartphones and tablets have and are still revolutionising the way we do business. Smartphones and tablets have significantly improved the way we do business and communicate, but it is the apps that you can download onto them that are likely to significantly change the way we do business in the future.

We already have apps that can scan and store your business cards, store details on your asset and save your important documents, but in the future you can expect many more effective, impressive apps. Some examples of apps which we may see developed in the future (or that are being developed now) are the likes of more powerful, real time translators, high performance graphic design apps, apps which make paying, transferring and receiving money much easier, human quality text to speech apps, and many more.

QB Robots

A US based company called Anybots have created a very cool little robot called QB, which uses the latest in wireless technology to create a portable webcam, so when conference calling, you almost feel as though you are in the room (thanks to your movable position) with your colleagues.

The robots have freedom of movement, so they can go anywhere in the office. On the head section of the QB, there is a webcam, so that you can see what the robot sees, and a screen, so you can be seen by those in the office.

QB means that you can be anywhere in the world, and yet still check up on those in the office, meaning that working out of the office is so much easier than ever before! QB could also help to significantly reduce the costs to businesses of travel, as fewer employees will need to be on the move.

3D Printing

3D printing is a new technology, which some critics say will be as big a revolution as the internet! 3D printing will allow firms to print products to order in store, bringing huge savings to firms in terms of transportation. Some predict that by the end of the decade, 3D printers will be a common household object, where we can print things, in 3D out of a whole range of different materials. I plan to write an article in the near future about 3D printing, so stay tuned!

UPDATE: I have now written that article, and it can be found here: 3D printing – a revolution on the horizon?

So, the future looks very exciting, but what do you think of it? Have you heard anything that I haven’t?

Nanobots – The future in Nanotechnology

5 Replies Hayley

This is Technology Bloggers 150th article 🙂
Well done and thank you to all our brilliant writers (Hayley included), as well as readers and commenters who have helped us get here!

A fraction of the ever-expanding field of nano-technology, nano-robots, a.k.a. nanobots, hold some of the most promising possibilities in the fields of technology, engineering and medicine. They also pose some of the most complex hurdles, such as automation, replication, control and finding viable energy sources to enable movement.

The Nano-Scale

Nanotechnology involves the study and micromanipulation of anatomic particles up to 1 nanometer, with scientists working to develop nanobots in fields less than 100 nanometers in size. Transmission electron (TEM), scanning electron (SEM), scanning tunneling (STM) and Atomic Force (ATM) microscopes are large, powerful machines that make all aspects of nanotechnology, including nano-robotics, possible.

Nano-microscopes allow researchers to isolate and observe single molecules, including chemical reactions that occur upon moving, eliminating and rearranging molecular structures. This base knowledge is essential to understanding, creating and ultimately finding solutions so that nanobot technology will reach its full potential.

Bottoms Up

Up until recent years, the development of nanotechnologies maintained “top-down” construction. The advent of “bottom up” creations on the nano-scale provide scientists the ability to create smaller objects; in addition, components can be “grown” to allow greater adaptation to specific environments or inclusion of specific properties.

Scientists are literally able to “grow” carbon nanotubes and “string” together nanowires, creating desired properties such as hastening conduction or reducing heat output – properties that make for tiny, efficient particles. In theory, by building a nanobot from the bottom up, scientists begin to find solutions that allow for greater control mechanisms and possibly self-replication of the nanobot.

Carbon nanotubes – building nanotechnology from the bottom up.

The greatest benefit of working bottom-up is that, rather than altering materials to work in a desired fashion, scientists build nanostructures and nanobots with proper compounds from the outset.

The Present

Although practical applications in medicine and technology have yet to be fully realized, nanobots are no longer figments of science-fiction imagination.

Lack of autonomy, largely associated with insufficient or unrealistic sources of energy, leaves a large barrier to the potential uses of nanobots. Batteries and solar sources are impractical due to size and, although a scientist can guide the nanobot with the use of magnets, they are not ideal. For example, a physician using a nanobot to treat a patient would need to maneuver the nanobot from outside the skin while also observing inner structures of the body.

Within the past year, scientists announced the creation of a nano “electric motor.” Utilizing principles of adsorption, a molecule attaches itself to the outside of a piece of copper; an STM probe focuses electrons onto the molecule, providing a source of energy and means to control direction. The large, cumbersome STM still makes this impractical in many ways; however, scientists are able to study this single motor and hypothesize ways to alter this and thus to apply it to nanobots.

In addition, micromanipulation made possible by electron microscopes allows for “DNA-walkers.” Essentially reprogramming a portion of a DNA strand, “molecular robots” or “spiders” walk autonomously; ultimately, scientists hope to further develop this technology, creating nanobots that fix genetic diseases.

The Future

Many scientists believe self-replication, most likely by programming the nanobot to micromanipulate surrounding atoms to create duplicates of its self, is essential to the realization of the many medical and technological applications.

In addition, a truly autonomous nanobot would be able to recognize, react and/or adjust to varying environmental conditions, including the presence of other nanobots; scientist could also program them for molecular assembly.

Many believe nanobots will allow for precise diagnostic capability and treatment of diseases such as cancer, as well as genetic disorders. Advances in communications, green energy, computer electronics and semi-conductors appear limitless.

Summary

Although still in its infancy, scientists across many fields hold much promise for nanobot technology. An autonomous nanobot, able to adapt its environment and self-replicate, could be the key to early detection and the cure of many diseases; in addition, nanobots will play an important role in sustainable or renewable energy sources, engineering and advancing computer technology.
