Read moreGold nanorods attach to, kill bladder cancer cells
Bladder cancer cells overexpress the protein EGFR; gold nanorods can be engineered to attach to EGFR proteins; and then the application of low-intensity laser to the tissue can preferentially heat these gold nanorods, killing the EGFR-rich cancer cells to which they are attached.

Read moreTrees go high-tech: process turns cellulose into energy storage devices
Chemists have found that cellulose - the most abundant organic polymer on Earth and a key component of trees - can be heated in a furnace in the presence of ammonia, and turned into the building blocks for supercapacitors.

Read moreEven thinner solar cells through use of nanoparticles?
Researchers have measured how irregularly distributed silver particles influence the absorption of light. They demonstrated that nanoparticles interact with one another via their electromagnetic near-fields, so that local 'hot spots' arise where light is concentrated especially strongly.

Read moreOrganic solar cells more efficient with molecules face-to-face
New research reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.

At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. Researchers have used the same phenomenon to build an optical device that may lead to new and more powerful computers that run faster and cooler.
