Nanodiamonds to help target cancer cells
Nanodiamond particles, or nanodiamonds (NDs), have emerged as a promising candidate for use in biomedical imaging and for different biomedical applications such as drug carrier platform. They show decreased cytotoxicity in comparison to other NPs, and can follow their fate by fluorescence imaging as a result of point defects in the diamond structure.

Brain-penetrating nanoparticle attacks deadly tumors
(Nanowerk News) Scientists have developed a new approach for treating a deadly brain cancer that strikes 15,000 in the United States annually and for which there is no effective long-term therapy. The researchers, from Yale and Johns Hopkins, have shown that the approach extends the lives of laboratory animals and are preparing to seek government approval for a human clinical trial.
“We wanted to make a system that would penetrate into the brain and deliver drugs to a greater volume of tissue,” said Mark Saltzman, a biomedical engineer at Yale and principal investigator of the research. “Drugs have to get to tumor cells in order to work, and they have to be the right drugs.

There's big news in the world of tiny things.
New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts with something that's 1,000 times thinner than the typical human hair – a semiconductor nanowire.

So kann der Sensor durch die Lunge und das Herz zirkulieren, ohne dort Schäden anzurichten.

Researchers are designing tiny particles to act as medicine.
The particles are coated with waterlike molecules that allow them to travel inside the body without being detected by the immune system, Farokhzad said. Their surfaces contain molecules that provide them with a "GPS" to seek out abnormal cancer cells.
Once they find a cancer cell, the particles stick, and like a Trojan horse, the cancer cells take them inside where they can release medicine that's toxic to the cell, Farokhzad said. [Watch the World Science Festival Live.]
In a study published last year in Science Translational Medicine, Farokhzad and colleagues showed that, in people, the nanoparticles delivered a much higher dose of medicine to cancer cells than to other cells in the body. Follow-up studies will test the effectiveness of the drug at treating tumors.

Currently nanotechnology is mainly used to produce nanoparticles, or materials with very specific properties. In the video http://youtu.be/mEH6tDLKcVU ; the superhydrophobic coatings shown at the beginning are one example. Graphene and carbon nanotubes are other nanoparticles with incredible potential in a variety of applications. |
