Apr 18, 2022 (Nanowerk News) Turmeric, a spice found in most kitchens, has an extract that could lead to safer, more efficient fuel cells. Researchers at the Clemson Nanomaterials Institute (CNI) and their collaborators from the Sri Sathya Sai Institute of Higher Learning (SSSIHL) in India discovered a novel way...
Chiral gold nanoparticles increase vaccine efficacy by more than 25%
Apr 18, 2022 (Nanowerk News) Vaccines can be made over 25% more effective by adding left-handed chiral gold nanoparticles as adjuvants, according to a study by an international collaboration in which Brazilian researchers took part. An article reporting the results is published in Nature ("Enantiomer-dependent immunological response to chiral nanoparticles")....
Graphene membranes capture low-level noise of a single bacterium
Apr 18, 2022 (Nanowerk News) Have you ever wondered if bacteria make distinctive sounds? If we could listen to bacteria, we would be able to know whether they are alive or not. When bacteria are killed using an antibiotic, those sounds would stop – unless of course the bacteria are...
The future of contact lenses
Apr 18, 2022 (Nanowerk Spotlight) What makes contact lenses so attractive for the development of all kinds of biosensors is the fact that they swim on a film of tears – and tear fluid, along with sweat and saliva, has tremendous potential for noninvasive monitoring biological signals because it contains...
Charging underwater and body-implanted electronic devices using ultrasonic waves
Apr 18, 2022 (Nanowerk News) As population ages and with the advancements in medical technology, the number of patients using implanted electronic devices, such as artificial pacemakers and defibrillators, is increasing worldwide. Currently, the batteries of body-implanted devices are replaced by an incision surgery, which may lead to health complications....
Visualizing spin angular momentum in water waves
Apr 18, 2022 (Nanowerk News) Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown (Science Advances, "Field theory spin and momentum in water waves"). This will help to provide new insights into very different wave...
