Researchers have developed a unique single-step process to achieve three-dimensional (3D) texturing of graphene and graphite. Using a commercially available thermally activated shape-memory polymer substrate, this 3D texturing, or 'crumpling', allows for increased surface area and opens the doors to expanded capabilities for electronics and biomaterials.
For the first time, scientists have succeeded in recording the current in membrane channels of contracting cardiac cells. To do this, the scientists combined an atomic force microscope with a widely used method for measuring electrical signals in cells.
Measurements have shown how spin filters forming within magnetic sandwiches influence tunnel magnetoresistance - results that can help in designing spintronic components.
Scientists are pioneering the use of nanomaterials in compact, sensitive, fast, low-cost terahertz detectors with potential in applications such as biomedical diagnostics, airport security screening and high data-rate wireless communication.
The latest 'Thematic Issue' publication explores recent developments in nanomaterials research, and possibilities for safe, practical and resource-efficient applications.
Researchers obtain conductivity values for stroncium iridate 250 times higher than in normal conditions, just pressing with nanometric needles. The results where obtained thanks to the use of the atomic force microscope (AFM) showing that the material could become a good candidate for future applications in sensors and electronics.
To construct ligand-directed ?active targeting? nanobased delivery systems, aptamer-equipped nanomedicines have been tested for in vitro diagnosis, in vivo imaging, targeted cancer therapy, theranostic approaches, sub-cellular molecule detection, food safety, and environmental monitoring.
Researchers have made an advance in manufacturing molybdenum disulfide. By growing flakes of the material around 'seeds' of molybdenum oxide, they have made it easier to control the size, thickness and location of the material.
Scientists in Australia propose a label-free electrochemical immunosensor based on functionalized vertical nanowire by means of a current patch clamp amplifi er which has not been previously reported.
Researchers suggest a way of enormously enhancing the van der Waals and Csimir forces - until they become a sort of 'quantum glue' holding atoms together.
Researchers manipulated zinc oxide, producing nanowires from this readily available material to create a ultra-violet light detector which is 10,000 times more sensitive to UV light than a traditional zinc oxide detector.
Molecular beam epitaxy systems enables scientists to control the properties of new crystals with exquisite precision, right down to the atomic level. They can grow nanomaterials with features just a few billionths of a meter across, and even control how many electrons they have inside them.
