Revolutionary nanotechnology illuminates brain cells at work

Until now it has been impossible to accurately measure the levels of important chemicals in living brain cells in real time and at the level of a single cell. Scientists at the Carnegie Institution's Department of Plant Biology and Stanford University are the first to overcome this obstacle by successfully applying genetic nanotechnology using molecular sensors to view changes in brain chemical l...

Nanotechnology to provide portable genetic risk detection

Currently being developed by the IST project OPTONANOGEN, a prototype of the system will initially be used to detect mutations of the BRCA1 gene that are responsible for between 2.5 and 5 per cent of the incidence of breast cancer in women. The final system, however, could be used to detect virtually any genetic anomaly as well as proteins linked to viruses, chemical contamination in food or wate...

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

Scientists at Stanford University have developed a new laser therapy that destroys cancer cells but leaves healthy ones unharmed. The new, non-invasive treatment is described in a study published in the Aug. 1 online edition of the Proceedings of the National Academy of Sciences (PNAS). "One of the longstanding problems in medicine is how to cure cancer without harming normal body tissue,"...

New, unique microscope for nanotech

UC Davis researchers in nanotechnology, chemistry and biology now have access to one of the most advanced microscopes of its type in the world. The new Spectral Imaging Facility, opened this fall, is a combination of an atomic force microscope and a laser scanning confocal microscope, the first commercial machine of its kind. The atomic force microscope was built by Asylum Research of Sant...

Nanotechnology may find disease before it starts

Nanotechnology may one day help physicians detect the very earliest stages of serious diseases like cancer, a new study suggests. In laboratory experiments on mice, scientists found that nano-sized particles injected into the animal...

CoQ10 bioavailability increased by Nanotechnology

The results of two human clinical trials support the enhanced bioavailability// of CoQ10 delivered into beverages using its novel technology which will interest manufacturers of CoQ10 products. Increasing its bioavailability, or the body's absorption of the ingredient, allows supplement and food makers to use lower dosages, therefore saving on costs. The patented technolo...

Nanotechnology Revolution To Be Spearheaded By European Union

Nanotechnology involves using tiny particles for treatment of diseases. ‘Nano’ refers to billionth of a unit. European countries are to use Nanotechnology for treatment of fatal diseases, which will help to reduce the cost of healthcare // . European Union to develop Nanotechnology in the next 10 years which will help to cure diseases such as heart diseases, diabetes, Cancer, HIV infection, Alzhe...

RNA Nanotechnology To Rescue Cancer Patients In Future

Scientists have now developed tiny delivery vehicles that can carry anticancer therapeutic agents directly into infected cells, using strands of genetic material constructed through nanotechnology, offering a potential wealth // of new treatments for chronic diseases. This emerging branch of science is called nanomedicine. These delivery agents are called nanoparticles, and are assembled...

Nanotechnologists Specify Limitation For Devising Small Machines

There's a limit to how tiny gadgets, devices and machines can get, scientists have claimed. The claim comes from an experiment performed by a University of Arizona// team of optical sciences doctoral candidate John D. Perreault and assistant professor of physics Alexander D. Cronin. Perreault and Cronin directly measured how close speeding atoms can come to a surface before...
