Gold 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.

Even 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.

Organic 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.

Nanoparticles aid the microscopic detection of a protein relevant for cancer

Researchers are currently developing a novel microscopy technology for the direct detection of individual subunits of protein complexes in the cell membrane of intact cells. The methodology is applied to investigate a protein complex acting as a calcium channel in the cell membrane. The channel plays an important role in prostate cancer.

Nanopores reveal amino acid fingerprints

Researchers have taken a major step toward the sequencing of proteins, demonstrating the accurate identification of amino acids, by briefly pinning each in a nanopore between a pair of flanking electrodes and measuring a characteristic chain of current spikes passing through successive amino acid molecules.

Groundbreaking optical device could enhance optical information processing, computers

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.
