Ultrasensitive imaging method uses gold-silver 'nanocages' (4/15/2010)

New research findings suggest that an experimental ultrasensitive medical imaging technique that uses a pulsed laser and tiny metallic "nanocages" might enable both the early detection and treatment of disease. The system works by shining near-infrared laser pulses through the skin to detect hollow nanocages and solid nanoparticles - made of an alloy of gold and silver - that are injected into the bloodstream. ...> Full Article

Lithium-ion anode uses self-assembled nanocomposite materials to increase capacity (3/16/2010)

A new high-performance anode structure based on silicon-carbon nanocomposite materials could significantly improve the performance of lithium-ion batteries used in a wide range of applications from hybrid vehicles to portable electronics. ...> Full Article

Special gold nanoparticles show promise for 'cooking' cancer cells (3/24/2009)

Researchers have developed the first hollow gold nanospheres -- smaller than the finest flecks of dust -- that search out and "cook" cancer cells. The cancer-destroying nanospheres show particular promise as a minimally invasive future treatment for malignant melanoma, the most serious form of skin cancer, the researchers say. Their study is scheduled for presentation in March at the 237th National Meeting of the American Chemical Society. ...> Full Article

Hollow gold nanospheres show promise for biomedical and other applications (3/23/2009)

A new metal nanostructure developed by researchers at the University of California, Santa Cruz, has already shown promise in cancer therapy studies and could be used for chemical and biological sensors and other applications as well. The hollow gold nanospheres have a unique set of properties, including strong, narrow and tunable absorption of light. ...> Full Article

Engineering Nanoparticles for Maximum Strength (10/22/2008)

Individual nanocrystals are remarkably strong. But under stress, complex nanostructures quickly fail because of internal strains. New research on hollow nanospheres shows that engineering can greatly increase the strength of complex nanoparticles. The results could lead to stronger nanostructures and large-scale alloys as well. ...> Full Article
