The next generation of electronics, as well as ultra-sensitive medical diagnostics, could depend on near atomic scale cracks - or nanogaps - in electrodes. Now, researchers have developed a method that could pave the way for mass production of nanogap electrodes.
Scientists have developed a new biosensor test system based on magnetic nanoparticles that is similar (in its principal) to a pregnancy test. This system is designed to provide highly accurate measurements of the concentration of protein molecules (e.g. markers, which indicate the onset or development of a disease) in various samples, including opaque solutions or strongly coloured liquids.
Researchers are developing nondestructive ways to detect damage in composites, using traditional medical inspection techniques such as X-rays and sonograms and advanced methods including infrared imaging, ultrasonic spectroscopy and computed tomography.
Researchers have developed a method for controlling the propagation of magnetic spin waves at the nanolevel in a targeted and simple way; so far, this required a lot of power. They have thus created a basis for nanocircuits that use spin waves.
