Dec 17, 2024 (Nanowerk News) The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of atoms. This has been demonstrated by the calculations of a team...
Metal-organic framework supercapacitor captures humidity to store energy
Dec 17, 2024 (Nanowerk Spotlight) When water evaporates and condenses in the atmosphere, it carries energy - the same process that drives weather patterns and can be harnessed for power generation. While power plants use temperature differences between water vapor and cooler surfaces to generate electricity on an industrial scale,...
Don’t burst that bubble: Research explores nanobubble stability
Dec 16, 2024 (Nanowerk News) Gases are essential for many chemical reactions, and bubbles are one way for these gases to be held in solution. When compared to larger bubbles, nanobubbles have increased stability—meaning that they can remain in a solution longer without popping. Due to their increased stability, they...
New blood test could make nanomedicine cancer treatments safer and more effective
Dec 16, 2024 (Nanowerk News) Scientists from RMIT University and the Doherty Institute have developed a new blood test that could screen cancer patients to help make their treatment safer and more effective. The first-of-its-kind test can rapidly assess how effective different polyethylene glycol (PEG) based nanomedicines are at killing...
Towards quantitative point-of-care testing with novel bioluminescent immunosensor
Dec 17, 2024 (Nanowerk News) A novel nanobody-based immunosensor, designed to function stably in undiluted biological fluids and harsh conditions, has been developed, as reported by researchers from Science Tokyo. Their innovative design leverages BRET—bioluminescence resonance energy transfer—and exhibits great potential for point-of-care testing, therapeutic drug monitoring, and environmental applications...
Researchers develop power-free color-changing strain sensor
Dec 16, 2024 (Nanowerk News) Wearable devices and smart sensors are transforming how we monitor health and activity, from tracking heartbeats to detecting body movements. However, traditional tools like stethoscopes and fitness trackers often face challenges. They require user training, struggle with accurately capturing subtle signals, and are limited in...
Researchers create microchips capable of detecting and diagnosing diseases
Dec 16, 2024 (Nanowerk News) In a world grappling with a multitude of health threats — ranging from fast-spreading viruses to chronic diseases and drug-resistant bacteria — the need for quick, reliable, and easy-to-use home diagnostic tests has never been greater. Imagine a future where these tests can be done...
Scientists develop on-chip living materials for portable chemical detection systems
Dec 16, 2024 (Nanowerk Spotlight) Chemical detection outside laboratory settings poses persistent technical challenges. Environmental monitoring, industrial quality control, and medical diagnostics require identifying specific molecules in complex mixtures. Current portable detection methods, such as test strips or electronic sensors, often lack sensitivity or struggle to detect multiple chemicals simultaneously....
Scientists develop 3D concrete printing method that captures carbon dioxide
Dec 16, 2024 (Nanowerk News) Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a 3D concrete printing method that captures carbon, demonstrating a new pathway to reduce the environmental impact of the construction industry. The innovative method, detailed in the scientific journal Carbon Capture Science & Technology ("Carbon...
