New nanosensor uses quantum dots to detect DNA

Using tiny semiconductor crystals, biological probes and a laser, Johns Hopkins University engineers have developed a new method of finding specific sequences of DNA by making them light up beneath a microscope. The researchers, who say the technique will have important uses in medical research,...

Researchers Create DNA-Based Sensors for Nano-Tongues and Nano-Noses

...e extremely sensitive to electrostatic variations in their environment, whether the nanotube is in a liquid or in air. "When the DNA portion of the nanosensor binds to a target molecule, there will be a slight change in the electric charge near the nanotube," Johnson said. "The nanotube will then pick up on ...

New security and medical sensor devices made possible by metallic nanostructures

... Professor Maier concludes: "This study is a beautiful example of how concepts from different areas of physics fertilise each other in essence our nanosensor system is a classical analogue of electromagnetically induced transparency, a famous phenomenon from quantum mechanics." ...

NASA MidSTAR-1 successful technologies may be revolutionary

...can sense chemicals and contaminants that may be harmful to astronauts, as well as a wide range of scientifically interesting compounds. "The chemical nanosensor is like a smoke detector that would fit on the end of an eraser," said Dan Powell, lead nanotechnologist for Goddard. The NCSU was developed by Dr. Ji...

Scientists discover how cancer may take hold

...stem allows the scientists to visually track the location and concentration of certain biochemicals. Our FRET technology with the novel tryptophan nanosensor has an added bonus, said Thijs. It can be used to identify new drugs that could reduce the ability of cancer cells to uptake tryptophan or their abili...
