Exploring the Antimicrobial Potential of Vanadium‐Based MXenes for Biomedical Applications
MicrobiologyOpen, Volume 15, Issue 3, June 2026.Vanadium‐based MXenes (V₂CTₓ and V₄C₃Tₓ) exhibit moderate antibacterial activity against E. coli and S. aureus, mainly through mechanical “nano‐knife” membrane disruption rather than ROS generation. These nanomaterials show good biocompatibility and highlight the importance of standardized experimental models for evaluating MXene antimicrobial ...

Stability and cooperativity in chimeric de novo TIM barrels via quarter swapping
Protein Science, Volume 35, Issue 6, June 2026.Abstract The use of repetitive units as building blocks in protein design, mimicking evolutionary duplication events, is a valuable strategy that reduces structural complexity. Such modular designs offer an opportunity to dissect how local contributions are integrated in a context‐dependent manner.
