Nanoscale Diagnostic Sets Sights on Alzheimer's

...netic particles sandwich the biomarker targets. A magnet separates the sandwich complexes from the rest of the sample. The complexes are then heated to release the DNA bar codes, which are then measured by an extremely sensitive detector. Each DNA piece greatly increases the sensitivity of the test and its...

Cellular scale drug delivery from the inside out

...tration of the principle, Lin holds a refrigerator magnet up to a liquid-filled glass vial containing human cervical cancer cells grown in vitro that contain nanospheres capped with iron-oxide particles. The cells slowly migrate and cluster to the side of the vial next to the magnet. "By using a powerful ...

Mitochondrial DNA sequencing tool updated

...chip. By crude analogy, each bit is like a unique magnet that sticks to its mirror image. But if the extracted DNA contains mutations or other variations from the standard consensus sequence annealed to the chip, the bits with those changes would appear abnormal to the specially designed computer softwa...

Rice scientists unveil 'nanoegg'

..., one positive and the other negative ?much like a magnet that attracts on one end and repels on the other. "Without a dipole moment, there is no 'handle' for light to grab hold of," Nordlander said. "In symmetric nanoshells, most of the light energy is lost to these 'dark modes.' With symmetry breaking, ...

Plants tell caterpillars when it's safe to forage

...he plant releases volatile compounds that act as a magnet for parasitic wasps ( Cotesia marginiventris ), which deposit their eggs in the larvae. Production of volatile chemicals increases during the day (when wasps are active) and decreases at night, suggesting that variations in production might affect th...

ABCB6 is key to production of heme in hemoglobin

...d have been repulsed--like two negative poles of a magnet pushing each other apart. Our work showed that ABCB6 overcomes that problem by simply grabbing porphyrin molecules and pulling them in. "We showed that there is a dynamic relationship between ABCB6 and the levels of heme and porphyrin that helps to...

Too mellow for our predatory world

... The islands in the Pacific Ocean continue to be a magnet for evolutionary biologists. Nowhere else is it possible to observe such a variety of different adaptation strategies in such a relatively small number of species. However, it is not only scientists who are drawn to the island; increasingly tourists ...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

...he probe - the component that is inserted into the magnet to obtain chemical information from the samples. Developed by scientists at the National High Magnetic Field Laboratory at UF and in Tallahassee, and a manufacturer of NMR equipment, the probe is only about 2 inches in diameter, and the space for th...
