Light-activated, drug-carrying liposomes show potential for minimally invasive glaucoma treatments

20 ноября, 2024 - 23:48
More than 4 million people in the U.S. have glaucoma, a group of eye diseases that can damage the optic nerve and lead to vision loss. It's the second-leading cause of blindness worldwide and there's currently no cure, but there's a way to help prevent vision loss through early detection and treatment.

Sugar-like nanoparticle covering could boost cancer drug delivery

20 ноября, 2024 - 22:47
A spoonful of sugar might actually help medicine go down, according to recent research from the University of Mississippi. And it could reduce the harmful side effects of cancer treatment. Instead of a literal spoonful of sugar, however, the researchers tried using glycopolymers—polymers made with natural sugars like glucose—to coat tiny particles that deliver cancer-fighting medication directly to tumors. They found that glycopolymers help keep proteins from sticking to the nanoparticles, reducing the body's immune response to the treatment.

New language encodes shape and structure to help machine learning models predict nanopore properties

20 ноября, 2024 - 19:47
A large number of 2D materials like graphene can have nanopores—small holes formed by missing atoms through which foreign substances can pass. The properties of these nanopores dictate many of the materials' properties, enabling the latter to sense gases, filter out seawater, and even help in DNA sequencing.

Machine learning and supercomputer simulations predict interactions between gold nanoparticles and blood proteins

18 ноября, 2024 - 23:36
Researchers in the Nanoscience Center at the University of Jyväskylä, Finland, have used machine learning and supercomputer simulations to investigate how tiny gold nanoparticles bind to blood proteins. The studies discovered that favorable nanoparticle-protein interactions can be predicted from machine learning models that are trained from atom-scale molecular dynamics simulations. The new methodology opens ways to simulate the efficacy of gold nanoparticles as targeted drug delivery systems in precision nanomedicine.

Cracking the code of performance degradation in solid oxide cells at the atomic level

18 ноября, 2024 - 20:38
Researchers have elucidated the mechanism of the initial degradation phenomenon that triggers the performance drop of high-temperature solid oxide electrolysis cell systems, using advanced transmission electron microscopy. Unlike previous studies, which analyzed the final stages of degradation at the micrometer scale, this study successfully verified the initial changes in electrolysis cell materials at the nanometer scale.

Electron imaging reveals the vibrant colors of the outermost electron layer

18 ноября, 2024 - 20:27
Surfaces play a key role in numerous chemical reactions, including catalysis and corrosion. Understanding the atomic structure of the surface of a functional material is essential for both engineers and chemists. Researchers at Nagoya University in Japan used atomic-resolution secondary electron (SE) imaging to capture the atomic structure of the very top layer of materials to better understand the differences from its lower layers. The researchers published their findings in the journal Microscopy.
