A new breathalyzer test, embedded with a 'NaNose' nanotechnology chip to literally 'sniff out' cancer tumors may turn the tide by both accurately detecting lung cancer and identifying its stage of progression.
Researchers implemented a detailed electrostatic model, which is capable of covering the full phenomenological range of interfacial energy-level alignment regimes within a single, consistent framework. Energy barriers/losses could be reproduced in both qualitative and quantitative agreement with a series of experiments.
Nanoparticles are becoming ubiquitous in food packaging, personal care products and are even being added to food directly. But the health and environmental effects of these tiny additives have remained largely unknown. A new study now suggests that nanomaterials in food and drinks could interfere with digestive cells and lead to the release of the potentially harmful substances to the environment.
All over the world researchers are investigating solar cells which imitate plant photosynthesis, using sunlight and water to create synthetic fuels such as hydrogen. Empa researchers have developed such a photoelectrochemical cell, recreating a moth's eye to drastically increase its light collecting efficiency. The cell is made of cheap raw materials - iron and tungsten oxide.
'Electroanalysis-Based Clinical Diagnostics' is an Electroanalysis Special Issue gathering the latest achievements in the design, fabrication and applications of electroanalysis-based devices in clinical field.
Scientists have found that two-dimensional nanostructures with asymmetric design enable a new quantum mechanism, triggering the emission of tuneable light at terahertz frequencies-with unprecedented efficiency.
Scientists have discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thought it could help them harvest energy from the sun much more efficiently. Working out its role in a living organism could lead to technological advances, such as better organic solar cells and quantum-based electronic devices.
