NEWS: Short List
Restraining and studying molecules, two at a time – Photonics | The usual way of studying how molecules react to a catalyst is to put them into a solution and observe – typically huge numbers of reactions. This works to a point, the point being the amount of detail that can be surmised from so [...]

Targeting cancer with magnetic microcarrier – Nanomedicine | As a rule chemotherapy is like using a blunderbuss against cancer. ‘Chemo’ is administered through the bloodstream, which of course goes everywhere in the body. While the anti-cancer chemistry can be targeted to a certain extent, it almost always has toxic side effects with other organs and [...]

Cosmology – Hubble does it again: Another oldest galaxy | Is there no end to the universe? Trick question, of course, but the succession of ever older galaxies discovered by the Hubble Space Telescope is provocative. In the newest instance, the galaxy discovered is 13.2 billion light years away, which is the same as saying [...]

Nanofibers produced like cotton candy
Think of it as nano-cotton candy. Even in English the fluffy balls of finely spun sugar have different names: Cotton candy (US), candyfloss (UK), fairy floss (Australia), but world-wide it’s a technique for creating airy, often colored confections. Why not apply this same technique for nanofibers? Why not indeed, thought a research team at Harvard [...]

A new line of defense: Plastic antibodies
Molecular biologists have been working on making artificial antibodies for over twenty years, which come to think of it, isn’t so long. Nature took many hundreds of millions of years to develop antibodies as the natural defense of living organisms against the onslaught of antigens such as bacteria, viruses, and other damaging invaders. The only [...]

Nanosponge delivers
Right up there in frequency with using nanotechnology for face powders has to be the myriad ways in which nanotech is, will, or can be used to deliver medicine. Why nanotech? For one thing, the nanoscale is small enough to be effective in attaching to or passing through cell membranes. Nanotech materials can be easier [...]

Nanotech spiders: On track with molecular robotics
You have to love it when the lead scientists on a project say: “You could imagine the spider carrying a drug and bonding to a two-dimensional surface like a cell membrane, finding the receptors and, depending on the local environment,” adds Yan, “triggering the activation of this drug.” Such applications, while intriguing, are decades or [...]

Coming: Toss the needles. Use a nanopatch.
There are a lot of reasons why decreasing the use of injection needles is a good idea – cost, safety, the fear factor. That’s why the use of sprays, liquids, lozenges, and patches are always popular – when they can be made effective for certain kinds of immunization and medical procedures. Researchers at Queensland University [...]

First human trials: Nanoparticles deliver anti-cancer siRNA
Human trials – that’s news. Nanoparticles that target cancer have been in the laboratories (and floating around rodent blood) for many years, but a team of researchers and doctors from the California Institute of Technology (Caltech, USA) has moved the tests (Phase I) to human subjects – into people with cancer. That’s a big step. [...]

New: Single molecule sensor array
If there is a spectrum that can be detected by sensors, from very small to very big, then the sensor array built by engineers at the Massachusetts Institute of Technology (MIT, Cambridge, USA) can stake a claim for the very smallest – a single molecule. The array uses carbon nanotubes, which are rapidly becoming the [...]

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 [...]

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.”

Stop the bleeding: Nanotech blood platelets
It’s a good example of the spreading use of nanotechnology – artificial blood platelets composed of nanoparticles. Platelets are a small blood-cell type and one of the principle components of blood coagulation, the process used by the body to stop bleeding. Applying nanotechnology to platelets is not an earth-shaking development but it seems a logical [...]
Nanosensors testing blood for cancer markers
Testing lab samples of blood is one thing; there’s lots of control achieved by isolating components of the blood before testing. Testing whole blood, unfiltered and with all components in their usual mix, is another thing. The thing is; testing whole blood is what’s required in the real world. Whole blood is complicated by the [...]
