Nanoparticle could help detect cancer and other diseases early

Researchers have created the first nanoparticle capable of detecting and imaging trace amounts of hydrogen peroxide in animals. The nanoparticles, thought to be completely nontoxic, could someday be used as a simple, all-purpose diagnostic tool to detect the earliest stages of any disease that involves chronic inflammation, including cancer, Alzheimer's disease, heart disease, and arthritis.

Gold nanorods image tumors

By linking gold nanorods to an antibody that binds to tumor cells, researchers have found that gold nanorods will align themselves in an ordered fashion on the surface of cancer cells, further intensifying the optical signal the nanorods produce and providing a unique optical signature for tumor cells.

Nanowire generates power by harvesting energy from the environment

As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy from the environment.
