NANOTECHNOLOGY UPDATE: Less Talk, But Plenty Of Action:
Nobody in the stock market gets excited about the phrase “nanotech” anymore. Which is strange, because nanotechnology itself – that is, the science and engineering conducted on a molecular scale, measuring less than 100 nanometers – is yielding applications and products in a number of industries, just as its more sensible supporters have long predicted. . . .
According to Google Trends, searches on “nanotechnology” have steadily trended downward to between 15% and 20% of the levels of a decade ago. Searches for “nanotech” – the catchy buzzword preferred by investors – have grown even quieter. And yet each year there are more interesting applications that wouldn’t be possible without nanotechnology.
One better-known example is semiconductors, which began employing a 65-nanometer manufacturing process in 2007. Intel this year announced a processor with transistors measuring 14 nanometers, small enough to fit 1.3 billion transistors on a chip, and is pushing for a 10-nanometer process.
Meanwhile, research for new drug therapies are increasingly relying on molecular-level science, while gold nanoparticles are being developed as way to diagnose and treat cancers. Touchscreens, LEDs, displays, batteries, water desalination, energy efficiency – all are areas that are benefiting from nanoscience, with products already in the market or approaching there. IBM, for example, is looking into carbon nanotubes as a promising alternative to silicon, which isn’t useful in transistors below 10 nanometers.
Nanotechnology never had its Facebook, its multibillion dollar blockbuster IPO that made clear how a new technology is changing the world. Instead, it’s enabling a lot of mostly incremental change in older industries. It may not be as visible as a social network, but it’s even more widespread. Most of the investments, however, have been coming not from VCs but from governments or deep-pocketed, diversified giants like IBM or GE.

Structural DNA nanotechnology predates RNA nanotechnology by a decade or more, and one of the key developments in building more complex nanostructures and devices from DNA has been DNA origami. So, what might we expect from last summer’s introduction of RNA origami?”
NANOTECHNOLOGY UPDATE: Automated synthesis expands nanotechnology building block repertoire. “The main limitation right now is that only 200 building blocks are available that carry both the halogen and the boronate groups, so only these can be used anywhere other than the first or last building block in the chain. If several thousand new building blocks become commercially available, it may not be too much of an exaggeration to talk about 3D printing of small molecules. . . . t will no doubt take several years to see just how big, how diverse, and how complex the products of this molecule synthesizer can be. It seems reasonable to expect a huge effect on drug discovery and other practical areas. Will it contribute to the development of APM? For example, could it synthesize small diamondoid parts? Could it produce useful catalysts or other functional components to attach to a large structural DNA framework? Or perhaps components for smaller, stiffer structural frameworks?” Faster, please.
Microscopic drones which can seek outand repair sections of artery damage could signal the future of treatments for heart disease and strokes, scientists claim.
Successful tests of the nanodrones have been carried out in mice – and researchers hope to conduct the first human trials soon.
The tiny particles are 1,000 times smaller than the tip of a human hair, and are designed to latch on to atherosclerotic plaques – hard deposits made from accumulated fat, cholesterol and calcium that build up on the walls of arteries and are prone to rupture, producing dangerous clots.
Once they have attached, they release a drug derived from a natural protein which can repair damage in the body.
In the mice, scientists found that just five weeks of treatment resulted in significant repairs to artery damage while the plaques were shrunk and stabilised, making it less likely for fragments to break off and cause clots.
