A gold–copper strategy for building interlocked nitrogen-doped carbon nanohoops in ssalimpour

Chronic gut inflammation can become self-reinforcing: damaged tissue produces reactive oxygen species (ROS) and inflammatory signals, which draw in immune cells that can cause further injury. 11/12/2026

Researchers adapted glutaraldehyde-functionalized glass to hold living bacteria firmly enough for nanometer-resolution atomic force microscopy while preserving high viability and, in one E. coli experiment, continued growth and division. The method enabled comparisons across bacterial species, LPS compositions, and cell orientations, revealing differences in outer membrane structure and growth-phase-dependent changes at bacterial poles. 11/11/2026

Researchers compared the transcriptomic effects of free manganese oxide nanoparticles with pristine and degraded graphene-MnO? composites in A549 human lung cells after 24 hours of exposure. Free MnO? triggered much broader changes in gene expression, including pathways linked to cellular stress and apoptosis, while the graphene-bound forms produced much smaller transcriptional responses. 11/10/2026
