An ultrathin invention could make future computing, sensing and encryption technologies remarkably smaller and more powerful by helping scientists control a strange but useful phenomenon of quantum mechanics, according to new research recently published in the journal Science ("Resonant metasurfaces for generating complex quantum states"). Scientists at Sandia National Laboratories and the Max Planck Institute for [...]
Methacrylate-based materials are often used in bone cement and dental resins. However, they have high failure rates as they undergo damage within ten years, impacting the quality of patient’s life and increasing healthcare costs. Although replacing methacrylate-based materials with self-healing resins and bone cement could increase lifespan, reduce costs, and enhance patient outcomes, the [...]
Early diagnosis of an infectious viral disease can help the patients and health care professionals monitor the outbreaks accurately and provide treatment at the early stage of a disease, avoiding any detrimental consequences. The accuracy of information is essential while monitoring such diseases to prevent any possible pandemics. An article published in the journal ACS [...]
Researchers at Duke University have developed a unique type of nanoparticle called a “nanorattle” that greatly enhances light emitted from within its outer shell. Loaded with light scattering dyes called Raman reporters commonly used to detect biomarkers of disease in organic samples, the approach can amplify and detect signals from separate types of nanoprobes [...]
A household microwave oven modified by a Cornell Engineering professor is helping to cook up the next generation of cellphones, computers and other electronics after the invention was shown to overcome a major challenge faced by the semiconductor industry. The research is detailed in a paper in Applied Physics Letters ("Efficient and stable activation by microwave [...]
Nanopore sensing has emerged as a versatile approach to detecting and identifying biomolecules. Within this frame of reference, the fast-responding ionic current is considered an essential criterion for accurately measuring small objects with a nanopore. An article published in the journal IScience discussed the role of ion diffusion kinetics at the liquid-electrode interface in nanopore [...]
Graphical abstract. Credit: Journal of Photochemistry and Photobiology B: Biology (2022). DOI: 10.1016/j.jphotobiol.2022.112551 Researchers at Queen's University Belfast have developed a plastic film that can kill viruses that land on its surface with room light. The self-sterilizing film is the first of its kind—it is low cost to produce, can be readily scaled and could be [...]
Nanotechnology that accelerates the transition of stem cells into bone could advance regenerative medicine. A nanotechnology platform developed by KAUST scientists could lead to new treatments for degenerative bone diseases. The system takes advantage of tiny iron wires that bend in response to magnetic fields. Bone-forming stem cells grown on a mesh of these [...]
Are sprays the future of COVID-19 vaccines? That’s the hope of dozens of research groups and companies working on new kinds of inoculation. Rather than relying on injections, these use sprays or drops administered through the nose or mouth that aim to improve protection against the virus SARS-CoV-2. This week, an inhaled version of [...]
Is the coronavirus on its way out? You might think so. New, updated booster shots are being rolled out to better protect against the variants circulating now. The U.S. Centers for Disease Control and Prevention has dropped COVID-19 quarantine and distancing recommendations. And more people have thrown off their masks and returned to pre-pandemic [...]
