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.
Researchers have presented a unique design and synthesis of hybrid carbon nanosheets, which show a strong solvatochromic behavior with wide color tunability ranging from blue to orange and even to white in various solvents.
Nanostructured piezoelectric interfaces own the actual potential to offer beneficial environments for cell and tissue stimulation, and, at the same time, they introduce new scenarios into nanomedicine, where nanomaterials, owing to their 'smart' properties, are exploited as active devices rather than as passive structural units or carriers for medications.
The new techniques, which investigated a common type of solar cell made of the semiconductor material cadmium telluride, promise to aid scientists in better understanding the microscopic structure of solar cells and may ultimately suggest ways to boost the efficiency at which they convert sunlight to electricity.
A team of scientists has developed a form of ultrastrong, lightweight carbon that is also elastic and electrically conductive. A material with such a unique combination of properties could serve a wide variety of applications from aerospace engineering to military armor.
The results could be exploited to develop smaller, higher-performance devices for use in a range of applications including molecular sensing, flexible electronics, and energy conversion and storage, as well as robust measurement setups for resistance standards.
Scientists have found a way to recover a protein structure after its chemical denaturation. The method is based on electrostatic interaction between folded, or denatured, proteins and alumina nanoparticles, which unwrap them.
