Dec 13, 2023 (Nanowerk News) Researchers at the Beckman Institute for Advanced Science and Technology and the Nick Holonyak Micro and Nanotechnology Laboratory developed a microscope that visualizes the invisible forces exerted by light at the nanoscale. This groundbreaking tool reveals the intimate tango between light, force, and temperature with...
Researchers develop spintronic probabilistic computers compatible with current AI
Dec 13, 2023 (Nanowerk News) Researchers at Tohoku University and the University of California, Santa Barbara have shown a proof-of-concept of energy-efficient computer compatible with current artificial intelligence (AI). It utilizes a stochastic behavior of nanoscale spintronics devices and is particularly suitable for probabilistic computation problems such as inference and...
Simple relation for optimizing enzyme reaction rates
Dec 13, 2023 (Nanowerk News) A surprising relationship that governs the activity of enzymes—the molecules that catalyze almost all the chemical reactions of life—has been uncovered by three RIKEN researchers (Nature Communications, "Thermodynamic principle to enhance enzymatic activity using the substrate affinity"). This finding could help researchers to select and...
Researchers predict protein placement on AFM substrates
Dec 13, 2023 (Nanowerk News) The observation of biomolecular structures using atomic force microscopy (AFM) and the direct visualization of functional conformational dynamics in high-speed AFM (HS-AFM) experiments have significantly advanced the understanding of biological processes at the nanoscale. In experiments, a biological sample is deposited on a supporting surface...
Propeller shape helps direct nanoparticles (w/video)
Dec 12, 2023 (Nanowerk News) Self-propelled nanoparticles could potentially advance drug delivery and lab-on-a-chip systems — but they are prone to go rogue with random, directionless movements. Now, an international team of researchers has developed an approach to rein in the synthetic particles. Led by Igor Aronson, the Dorothy Foehr...
