Sep 08, 2023 (Nanowerk News) A paper published in the journal Monthly Notices of the Royal Astronomical Society ("Stellar-mass black holes in the Hyades star cluster?") hints at the existence of several black holes in the Hyades cluster — the closest open cluster to our solar system — which would...
Researchers define a nanopipette fabrication protocol for high resolution cell imaging
Sep 08, 2023 (Nanowerk News) A nanoscale view of living cells can provide valuable insights into cell structure and function. Over the years, various microscopy techniques have been enrolled to obtain a window into biological specimens at the nanoscale but all with their limitations and challenges. Although scanning ion conductance...
Nanoparticles will change the world, but whether it’s for the better depends on decisions made now
Sep 07, 2023 (Nanowerk News) Technologies based on nanoscale materials – for example, particles that are more than 10,000 times smaller than the period at the end of this sentence – play a growing role in our world. Carbon nanofibers strengthen airplanes and bicycle frames, silver nanoparticles make bacteria-resistant fabrics,...
New nanoparticle system unleashes the immune system on metastases
Sep 07, 2023 (Nanowerk News) A new nanocomplex renders a tumor harmless – and, on top of that, it trains the immune system to detect and eliminate metastases. An international research team headed by Dr. Johannes Karges of the Faculty of Chemistry and Biochemistry at Ruhr University Bochum, Germany, has...
Novel device combines nanopores with electronic signals for disease detection
Sep 07, 2023 (Nanowerk News) In living organisms, cells have a very high capacity to process and communicate information by moving molecules or ions through tiny channels that span the cell membrane. UC Santa Cruz Professor of Electrical and Computer Engineering Marco Rolandi’s lab and collaborators at MIT have created...

Innovative plasmonic nanotweezer rapidly traps potentially cancerous nanosized particles
Sep 07, 2023 (Nanowerk News) Vanderbilt researchers have developed a way to more quickly, and precisely, trap nanoscale objects such as potentially cancerous extracellular vesicles using a cutting-edge plasmonic nanotweezer. The practice by Justus Ndukaife, assistant professor of electrical engineering, and Chuchuan Hong, a recently graduated Ph.D. student from the...
New loss mitigation technique paves the way for perfect optical resonators
Sep 06, 2023 (Nanowerk News) Optical resonators are used in everything from familiar laser pointers to cutting-edge photonic quantum computers. But they all suffer from losses that degrade their performance. Researchers at Aalto University have now developed a way to prevent those losses, boosting the resonators’ performance. The role of...
