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...
Light activated nanomedicine ushers in a new era for age-related macular degeneration therapy
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...
New platform solves key problems in targeted drug delivery
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...
CRISPR enhanced nanotweezers for ultra-precise DNA manipulation and detection
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...
From skyrmions to hopfions
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...
New study shows how heat can be used in computing
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...
