Nanotech could revolutionise global healthcare

In Disabled People, Health, nano on March 3, 2007 at 5:01 pm

Nanotechnology has the potential to generate “enormous” health benefits for the more than five billion people living in the developing world, according to a leading professor of medicine.

My comment: Its much too simple as its outlined in the article more drugs more technology do not good as such if the societal framework (not just related to businesses) is changed. But that does not just mean to direct more tech research priorities towards the needs of the poor. It also means to look at whether new research is actually needed and whether existing tech and sciences can deal with the problem. We have today drugs sciences and technologies who do not reach the people in need. Further more often social changes are much more effective in fighting diseases and preventing the increase of people with a given disease and to make the lives of the poor better than just producing more drugs or technologies.

To slow the progress of Parkinson’s disease, doctors planted electrodes deep in my brain. Then they turned on the juice.

Nanoparticle Research Offers Hope of Artificial Retinas, Prostheses

In Disabled People, Health, nano on March 3, 2007 at 4:46 pm

Here’s how nano research might pave the way to the development of artificial retinas based on photosensitive nanoparticles:

The world’s first direct electrical link between nerve cells and photovoltaic nanoparticle films has been achieved by researchers at the University of Texas Medical Branch at Galveston (UTMB) and the University of Michigan. The development opens the door to applying the unique properties of nanoparticles to a wide variety of light-stimulated nerve-signaling devices — including the possible development of a nanoparticle-based artificial retina.

Nanoparticles are artificially created bits of matter not much bigger than individual atoms. Their behavior is controlled by the same forces that shape molecules; they also exhibit the bizarre effects associated with quantum mechanics. Scientists can exploit these characteristics to custom-build new materials “from the bottom up” with characteristics such as compatibility with living cells and the ability to turn light into tiny electrical currents that can produce responses in nerves.
