NEWS: Short List

Cell Biology – Biological clocks: Circadian rhythms not dependent on DNA | It has long been assumed that the internal clocks in all living things (loosely called the Circadian rhythm) is associated with DNA. Apparently, they are not. A new study by the universities of Cambridge and Edinburgh (UK) has shown that red blood cells [...]

New Report: The Construction Nanomaterials Revolution

Of the many ongoing technology developments, it’s arguable that nanotechnology will have the most immediate, visible, and continuing impact. Nano-this and nano-that have already sprung up in the English vocabulary like mushrooms after rain and marketing-speak has long since incorporated the benefits of NEW: With Nano-whatever. Barely a week goes by without an announcement of [...]

A coming marriage: Additive Manufacturing and Nanotechnology

It could be a marriage made in engineering heaven: Additive manufacturing and nanotechnology. First, let’s introduce additive manufacturing. Throughout history manufacturing of metallic parts and most other materials as well starts with a solid shape of the material and gets cut down to size. If you want to make a sword, you first get a [...]

Two new cancer-killing nanoparticles

To use an overworked phrase, it’s a paradigm shift: Cancer research is learning how to ‘think small’ with the potential of nanotechnology – nanoparticles specifically. It’s a shift because medical science has been accustomed to cancer-fighting techniques on the level of bringing cannons to kill a fly. Where doctors once treated cancer with a body-wide [...]

Nanoparticles identify metastasized cancer cells

One of the more common techniques evolving from the use of nanoparticles to study cell biology is the ability to ‘tag’ cells with colored (dyed) nanoparticles. In an important application of this technique, researchers at the Georgia Institute of Technology (USA) have been able to tag cancer cells that travel in the blood of mice [...]

“I thought to myself, ‘That’s really interesting …’”

Rice University graduate student Cary Pint looked at the tweezers he was using to pull a sample; they were coated with carbon nanotubes. “That’s really interesting….” In fact, precisely what he was researching – how to make carbon nanotubes stick to various surfaces. Light bulb time. The Eureka! moment. Perhaps not exactly, but at the [...]

It had to happen: a medical “nano cocktail”

Sooner or later it would occur to medical nanotechnology researchers that combining various nanoparticles – and loading them with targeted drugs – might be more effective than administering them one by one. Of course, in the new tradition of packaging medical combinations in a marketable phrase, this is a “nano cocktail.”

Prevent oxidation with nanoparticles derived from corn

News about nanotechnology is reported almost every day. Nanotechnology in agriculture, not so much. Nanotechnology made from agricultural products, we hear about that even less. So this story concerning research done at Purdue University (Indiana, USA), which uses nanoparticles manufactured from corn to extend the shelf life of certain oils demonstrates the radiation of nanotech [...]

New rocket fuel: aluminum ice

ALICE to the stars! Could be a catchy title. It’s an acronym: ALuminum ICE, a new kind of rocket fuel. There are lots of ways to drive a rocket. Few of them are ecologically friendly. This one may be. Better still, aluminum nanoparticles and water (hydrogen and oxygen) for rocket fuel are potentially available for [...]

Nanoparticles for cancer drug delivery

You’re going to see many stories of drug delivery methods using nanotechnology. Some methods are still quite theoretical; others have already reached the testing stage in animals. Note, however, that so far none have been given the green light for human testing, which says something about the nascent status of the nano-medical field. Much of [...]

‘Natural’ self-assembly of nanoparticles

Somewhere along the line nanotechnologists have got it into their heads that nanoparticles ought to do self-assembly. Oh wait. They may have met a biologist. Living things do self assembly all the time, and much of it takes place at the molecular nanoscale. So why not nanotechnology? (Uh, life took millions of years to achieve [...]

Meet the hot dot-Janus particle

One of the big research tracks for nanotechnology is the ability to control the alignment and shape of nanoparticles. Control is vital for nano-manufacturing (building something with nanoparticles) and also for many medical uses of nanotechnology. “Control” in this sense means the ability to move nanoparticles on command in any dimension with the ultimate control [...]
