Researchers have now managed to pinpoint what happens when light is absorbed by extremely small nanoclusters of silver atoms. The results may have useful application in the development of biosensors and in imaging.
Researchers designed a hyperbolic metasurface with a nanogroove structure in the subwavelength scale. Its enhanced plasmonic sensing performance is two orders of
magnitude higher than those with current state-of-art plasmonic metamaterials and metasurfaces.
Researchers have developed a leaching process to produce ultrafine jagged platinum nanowires. The wires have with extraordinary surface activity and high surface areas. Combined, these features deliver a catalyst with a record-high conversion rate.
Flexible electronic parts could significantly improve medical implants. However, electroconductive gold atoms usually hardly bind to silicones. Researchers have now been able to modify short-chain silicones in a way, that they build strong bonds to gold atoms.
Using spins as elementary units in computing and highly efficient electronics is the ultimate goal of spintronic science because of spintronics minimal energy use. In a new study, researchers manipulated and amplified the spin current through the design of the layered structures, a vital step towards this goal.
Engineers have invented biosensor technology - known as a lab on a chip - that could be used in hand-held or wearable devices to monitor your health and exposure to dangerous bacteria, viruses and pollutants.
