Jul 21, 2023 (Nanowerk News) An interdisciplinary research team from Bochum, Duisburg and Zurich has developed a new approach to construct modular optical sensors which are capable of detecting viruses and bacteria. For this purpose, the researchers used fluorescent carbon nanotubes with a novel type of DNA anchors that act...
New graphene transistor sensor mimics cell membrane functions
Jul 21, 2023 (Nanowerk News) Drawing inspiration from natural sensory systems, an MIT-led team has designed a novel sensor that could detect the same molecules that naturally occurring cell receptors can identify. In work that combines several new technologies, the researchers created a prototype sensor that can detect an immune...
Nano-size carbon material could be used to treat Down syndrome
Jul 21, 2023 (Nanowerk News) Scientists at the Texas A&M University Health Science Center (Texas A&M Health) have discovered that a nano-sized carbon material derived from the oxidation of carbon-rich sources could be used to treat Down syndrome and other disorders associated with high levels of hydrogen sulfide. Hydrogen sulfide...
Steering ‘microswimmers’ through choppy waters
Jul 21, 2023 (Nanowerk News) New research looks at navigation strategies for deformable microswimmers in a viscous fluid faced with drifts, strains, and other deformations. A deformable microswimmer is a small-scale organism or artificial structure that uses sinusoidal body undulations to propel itself through a fluid environment. The term applies...
Hubble sees boulders escaping from asteroid dimorphos
Jul 21, 2023 (Nanowerk News) The popular 1954 rock song "Shake, Rattle and Roll," could be the theme music for the Hubble Space Telescope's latest discovery about what is happening to the asteroid Dimorphos in the aftermath of NASA's DART (Double Asteroid Redirection Test) experiment. DART intentionally impacted Dimorphos on...
Revolutionizing light control with a new class of crystals
Jul 21, 2023 (Nanowerk Spotlight) Manipulating light at dimensions smaller than its wavelength, a scale known as the subdiffractional scale, is a critical capability in various fields such as imaging, optical communication, integrated optical circuits, and molecular sensing. A promising way to control light at this tiny scale is through...
Simultaneous synthesis and fixing of covalent organic frameworks
Jul 21, 2023 (Nanowerk News) An electrogenerated acid can catalyze the synthesis and simultaneous immobilization of imine-based covalent organic frameworks (COFs) onto electrodes, report scientists from Tokyo Tech. Starting with amine and aldehyde monomers, they obtained corresponding COF films, including three-dimensional ones, with high crystallinity, porosity, and controlled thickness. This...
Researchers put a new twist on a graphite-graphene interface
Jul 19, 2023 (Nanowerk News) For decades, scientists have been probing the potential of two-dimensional materials to transform our world. 2D materials are only a single layer of atoms thick. Within them, subatomic particles like electrons can only move in two dimensions. This simple restriction can trigger unusual electron behavior,...
New kind of superresolution explores cell division
Jul 20, 2023 (Nanowerk News) A new way to see details smaller than half the wavelength of light has revealed how nanoscale scaffolding inside cells bridges to the macroscale during cell division. Unlike earlier superresolution techniques, the one developed and tested at the University of Michigan doesn’t rely on molecules...
