Nov 27, 2023 (Nanowerk News) Richard Feynman famously stated, “Everything that living things do can be understood in terms of the jigglings and wigglings of atoms.” This week, Nature Nanotechnology ("Single-molecule force stability of the SARS-CoV-2–ACE2 interface in variants-of-concern") features a groundbreaking study that sheds new light on the evolution...

Nov 27, 2023 (Nanowerk News) Researchers at the LKS Faculty of Medicine of the University of Hong Kong (HKUMed), and collaborators from the Zhongshan Ophthalmic Centre of Sun Yat-sen University, Guangzhou, have developed a light-activatable prodrug nanomedicine for age-related macular degeneration (AMD) therapy. Through the intravenous injection of the nanomedicine...

Nov 27, 2023 (Nanowerk News) In recent years, cell and gene therapies have shown significant promise for treating cancer, cystic fibrosis, diabetes, heart disease, HIV/AIDS and other difficult-to-treat diseases. But the lack of effective ways to deliver biological treatments into the body has posed a major barrier for bringing these...

Nov 27, 2023 (Nanowerk News) Since the concept of optical trapping was first proposed in the 1960s and 1970s by Arthur Ashkin, researchers have pursued innovative techniques to precisely manipulate and analyze individual biomolecules like DNA. Such capabilities would revolutionize genetics, molecular biology, and medicine by enhancing our understanding of...

Nov 27, 2023 (Nanowerk News) Exotic magnetic structures such as skyrmions are also known as topological particles. Because they can be easily moved within a crystal, they are envisioned as promising information carriers of the future. Scientists from Jülich, China and Sweden have now created and observed for the first...

Nov 27, 2023 (Nanowerk News) Physicists at Martin Luther University Halle-Wittenberg (MLU) and Central South University in China have demonstrated that, combining specific materials, heat in technical devices can be used in computing. Their discovery is based on extensive calculations and simulations. The new approach demonstrates how heat signals can...

Contents Just as nanoplasmonics reveals the fascinating interplay between light and metal nanoparticles, nanophotonics ventures into the broader realm of light manipulation at the nanometer scale. It explores how photons, the fundamental particles of light, interact with nano-sized structures, opening avenues for innovation in various technological fields. Nanophotonic structures have...

Nov 25, 2023 (Nanowerk Spotlight) Since the early 1990s, the quest to enhance virtual, augmented, and mixed reality experiences has driven researchers to innovate in the field of haptic interfaces. These interfaces aim to provide realistic touch feedback, a critical component for fully immersive digital environments. However, developing haptic systems...

Nov 24, 2023 (Nanowerk News) A recent study published in Nature Methods ("Peptide sequencing based on host–guest interaction-assisted nanopore sensing") showcases the development of a revolutionary protein sequencing technology, promising significant advances in the fields of proteomics and clinical diagnostics. This research, led by Prof. Haichen Wu from the Institute...

Nov 24, 2023 (Nanowerk News) Microrobotics has advanced rapidly in recent years, allowing scientists to build minuscular machines able to penetrate hard-to-reach environments from inside the human body to contaminated waste sites. Propelling these tiny robots requires clever solutions, as their tiny size means they operate in a realm dominated...
