Influence of Crystal Shape and Orientation on the Magnetic Microstructure of Bullet-Shaped Magnetosomes Synthesized by Magnetotactic Bacteria

Magnetotactic Bacteria (MTB) are a group of microorganisms capable of biomineralizing magnetosomes. Magnetosomes are membrane-bound magnetic nanocrystals primarily composed of magnetite (Fe₃O₄) or greigite (Fe₃S₄). These magnetosomes are arranged in chains or specific orientations within bacterial cells, endowing the bacteria with a magnetic dipole...

Facile Fabrication of Injectable Multifunctional Hydrogels Based on Gallium-Polyphenol Networks with Superior Antibacterial Activity for Promoting Infected Wound Healing

A Novel Study on Multifunctional Hydrogels for Promoting Infected Wound Healing In the current clinical setting, infected wounds, especially those caused by antibiotic-resistant pathogens, have become a major challenge. These chronic or hard-to-heal wounds often suffer from delayed healing processes due to excessive inflammation, bacterial biofilm ...

A Spectroscopic Method for Distinguishing Two Novel Sandwich-Type Tungsten Oxide Cluster Compounds

Distinguishing Novel Sandwich-Type Tungsten Oxide Cluster Compounds Using Two-Dimensional Correlation Infrared Spectroscopy Background Introduction Polyoxometalates (POMs) are metal-oxygen cluster compounds linked through oxygen coordination with transition metal ions. They play significant roles in catalysis, optics, medicine, and magnetism. Howev...

Ion-Concentration-Dependent Dynamic Mechanism of Thiolactic-Acid-Capped Gold Nanoclusters Revealed by Fluorescence Spectra and Two-Dimensional Correlation Spectroscopy

Background and Research Questions Atomic gold nanoclusters (AuNCs), with particle sizes typically not exceeding 2 nanometers, have garnered extensive attention in recent years due to their unique photophysical properties, making them highly advantageous in biomedicine, catalysis, and sensing. These properties include excellent catalytic activity, t...
