Feb 09, 2024 (Nanowerk News) In quantum sensing, atomic-scale quantum systems are used to measure electromagnetic fields, as well as properties like rotation, acceleration, and distance, far more precisely than classical sensors can. The technology could enable devices that image the brain with unprecedented detail, for example, or air traffic...
New AI tool discovers realistic metamaterials with unusual properties (w/video)
Feb 09, 2024 (Nanowerk News) A coating that can hide objects in plain sight, or an implant that behaves exactly like bone tissue. These extraordinary objects are already made from metamaterials. Researchers from TU Delft have now developed an AI tool that not only can discover such extraordinary materials but...
Novel cancer nanodrug targets tumor acidity without harming healthy tissue
Feb 09, 2024 (Nanowerk News) A multidisciplinary research team at Vanderbilt University and Vanderbilt University Medical Center has discovered a new way to kill a tumor by disrupting its acidic “microenvironment” without harming normal tissue. The target of this unorthodox approach is hydroxyapatite (HAP), a naturally occurring mineral that is...
Mussle-inspired coating process enables rapid fabrication of wafer-scale nanoparticle films
Feb 09, 2024 (Nanowerk Spotlight) Nanoparticles exhibit intriguing size-dependent optoelectronic properties with applications across biomedicine, energy, sensing and more. However, the exquisite precision synthesizing discrete nanoparticles contrasts sharply with immense difficulty manipulating them over significant lengths. Researchers worldwide have struggled for decades to efficiently organize nanoparticles across wide areas or...
The humble bandage gets a smartphone-powered electronic upgrade
Feb 09, 2024 (Nanowerk News) For millions suffering from chronic lesions, burns and post-surgical complications, their wounds can mean persistent pain, risk of infection, and reduced quality of life. And while modern medicine has tremendously expanded treatment options, there has been minimal innovation in one ubiquitous remedy – the humble...
Towards a better way of releasing hydrogen stored in hydrogen boride sheets
Feb 09, 2024 (Nanowerk News) The looming threat of climate change has motivated scientists worldwide to look for cleaner alternatives to fossil fuels, and many believe hydrogen is our best bet. As an environmentally friendly energy resource, hydrogen (H2) can be used in vehicles and electric power plants without releasing...
Deep learning for real-time molecular imaging
Feb 09, 2024 (Nanowerk News) National University of Singapore (NUS) researchers have demonstrated that deep learning allows them to observe the dynamics of single molecules more precisely and with less data than traditional evaluation methods. They used convolutional neural networks (CNNs) to observe the movement of single molecules in artificial...
Advanced measurements unravel nanoscale phenomena
Feb 07, 2024 (Nanowerk News) Semiconductor 2D materials are a few atoms thick, and some of them exhibit localised emission, where light is emitted from such a small part of the layer that only one photon at a time is produced. This localised emission has unique properties and is vital...
Nanomaterial biosensor for fast and cost-effective pathogen detection
Feb 07, 2024 (Nanowerk News) The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team led by Dr. Larysa Baraban at the at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) develops intelligent, miniaturized biosensor devices and...
A new ‘metal swap’ method for creating lateral heterostructures of 2D materials
Feb 08, 2024 (Nanowerk News) Electronically conducting two-dimensional (2D) materials are currently hot topics of research in both physics and chemistry owing to their unique properties that have the potential to open up new avenues in science and technology. Moreover, the combination of different 2D materials, called heterostructures, expands the...
