This evolving treatment approach involves the injection of nanoparticles into the tumor, which are then activated with magnetic energy. Once activated the nanoparticles produce heat inside the cancer cell. The heat kills the cancer cell with minimal damage to surrounding tissue.
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.
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.
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.
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.
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.
The new method synthesizes large-area graphene into a single crystal on a semiconductor, maintaining its electric and mechanical properties. The new method repeatedly synthesizes single crystal graphene on the current semiconductor wafer scale.
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.
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.
