Diimmonium Nano-Agents Improve Photoacoustic Imaging Contrast At 1700 nm in ssalimpour

Researchers developed diimmonium DB·2X nano-agents that support photoacoustic imaging at 1700 nm, with DB·2TFSI showing strong performance in preclinical imaging experiments. In mouse models, 1700 nm imaging reduced endogenous background interference and improved signal-to-background ratios compared with 1064 nm, supporting further investigation of NIR-IIb photoacoustic contrast agents. 10/26/2026

Researchers developed a rapid, one-pot method that used sunlight and a commercial vincristine formulation to form gold nanoparticles within five minutes without separate reducing or stabilizing agents. The particles retained vincristine’s antiproliferative activity against Colo-205 colon cancer cells and showed greater DPPH radical scavenging than free vincristine at several tested concentrations, while questions about drug photostability, release, stability, and in vivo performance remain. 10/22/2026

Researchers engineered hybrid strontium sulfite nanoparticle-modified lipid nanoparticles to deliver p53 mRNA, producing higher reporter-gene expression, higher p53 transcript levels, and greater apoptosis in breast cancer cells than conventional LNPs. In mice, the p53 mRNA-loaded hybrid carrier slowed 4T1 tumor growth, although the study was small and preclinical, and the clearest biodistribution advantage appeared after PEGylation. 10/21/2026

Researchers developed a high-throughput workflow that combined cryogenic spectroscopy, automated statistical analysis, and scanning transmission electron microscopy to link fabrication conditions and junction microstructure to the strongly coupled two-level system (TLS) density across about 6,000 Al/AlOx/Al Josephson junctions. They found that thicker aluminum electrodes and larger grains were associated with an approximately two-thirds lower detectable TLS density, while the precise microscopic cause remains unresolved. 10/20/2026
