Near-infrared resonant nanoshells for combined optical imaging and photothermal cancer therapy

Using metal nanoshells designed to both absorb and scatter near-infrared light, a team of investigators at Rice University has shown that such nanoparticles can both image and treat tumors in animals. Their experiments revealed complete tumor destruction in more than 80 percent of animals treated with these nanoshells.

Early detection of Alzheimer's coming soon?

Alzheimer's disease is the most common form of old-age dementia and has become the fourth most common cause of death in the USA. The cause of the disease is protein deposits, called amyloid plaques, in the brain.

A unique new non-invasive technique for high resolution optical imaging of the eye

The technique, pioneered by the University of Kent, is funded by the Toronto-based company, Ophthalmic Technology Inc (OTI). The University’s Applied Optics Group is currently working with university hospitals in New York (USA), Osaka (Japan), Asahikawa (Japan), Amsterdam (Netherlands) and Milan (Italy) to carry out preliminary clinical trials.

Miniature spectroscopic instruments and software to look at changes that occur within the cells and tissue of the brain

When molecules in cells are stimulated by light, they respond by becoming excited and re-emitting light of varying colors (fluorescence) that can be captured and measured by highly sensitive optical equipment.

Technique to visualize changes in nerve connections when flies learn may help to understand how memories form

For the first time, researchers have used a technique called optical imaging to visualize changes in nerve connections when flies learn. These changes may be the beginning of a complex chain of events that leads to formation of lasting memories.
