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.

To bridge LEDs' green gap, scientists think small - really small

Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes, especially in the 'green gap', simulations have shown. Nanostructure LEDs made from indium nitride could lead to more natural-looking white lighting while avoiding some of the efficiency loss today's LEDs experience at high power.

Probing the next generation of 2D materials

Molybdenum disulfide (MoS2) is part of a wider group of materials known as transition metal dichalcogenides and has been put forward by researchers as a potential building block for the next generation of low-cost electrical devices.
