Nanoparticles are found in many everyday products, from cosmetics and textiles to air pollution. While they offer many benefits, scientists still need better ways to understand how long-term exposure may affect our skin. Researchers from Alfaro-Moreno group at INL have developed a new skin-on-a-chip platform that closely mimics human skin, providing a more realistic way to study how nanoparticles interact with our body's first protective barrier. Unlike conventional lab model

Researchers at the University of Osaka have developed an autonomous solid-state nanopore that senses molecules, generates electrical signals, and retains memory of recent events without external control. Chemical reactions inside the pore continuously reshape its structure, producing molecule-specific signal patterns. Machine learning distinguished DNA nucleotides and amino acids from these signatures. Published in ACS Nano.

Scientists have developed “glycan atlassing,” a breakthrough super-resolution technique that maps the precise nanoscale architecture of sugars on cell surfaces. Published in Nature Nanotechnology, the method reveals that the spatial organization of glycans encodes critical information about cell state — opening powerful new possibilities for cancer diagnostics, stem cell research, and precision nanomedicine.

The study serves as a benchmark for quantum chemical methods in modeling phosphate-containing clusters, opening new pathways for designing more efficient proton-conducting materials and understanding biological proton transfer.

Over the decades, many strains of disease-causing bacteria have evolved defenses to even the most potent antibiotics, setting off a growing health crisis. The rise of antibiotic-resistant “superbugs” has also set off an arms race. As germs find new ways to withstand drugs, researchers are looking for new ways to break down their defenses. In a significant step forward, a research team led by Yan Yu, the Art Krieg Professor of Chemistry, in Arts & Sciences, and of biomedical e

Visible light can be used to create electrodes from conductive plastics completely without hazardous chemicals. This is shown in a new study carried out by researchers at Linköping and Lund universities, Sweden. The electrodes can be created on different types of surfaces, which opens up for a new type of electronics and medical sensors.
