Abstract Diabetic wounds are a major devastating complication of diabetes due to hyperglycemia, bacterial invasion, and persistent inflammation, the current antibiotic treatments can lead emergence multidrug‐resistant bacteria. Herein, bimetallic nanozyme‐based biomimetic bio‐cocklebur (GNR@CeO 2 @GNPs) is designed synthesized for diabetic wound management by depositing spiky ceria (CeO ) shells gold nanoparticles (GNPs) on nanorod (GNR) nanoantenna. The plasmonic‐enhanced nanozyme catalysis self‐cascade reaction properties simultaneously boost two‐step enzyme‐mimicking catalytic activity GNR@CeO @GNPs, leading significant improvement in overall therapeutic efficacy rather than mere additive effects. Under glucose activation 808 nm laser irradiation, @GNPs material captures photons promotes transfer hot electrons from GNR GNPs into CeO , realizing “butterfly effect” consuming local glucose, overcoming limited antibacterial efficiency an individual PTT modality, providing substantial reactive oxygen species. In vitro vivo experiments demonstrate material's exceptional antibiofilm against Gram‐negative Gram‐positive bacteria, which reduce promote collagen deposition, facilitate angiogenesis, thereby accelerating healing. This study provides promising new strategy develop nanozymes with cascade mode antibiotic‐free synergistic treatment infected wounds.

Abstract The continuous exploration of new analogs calixarenes and pillararenes unlocks infinite opportunities in supramolecular chemistry materials. In this work, we introduce a class macrocycle, phenyl‐extended resorcin[4]arenes ( ExR4 ), unique innovative design that incorporates unsubstituted phenylene moieties into the resorcin[4]arene scaffold. Single‐crystal analysis reveals chair‐like conformation for per‐methylated Me‐ExR4 ) twisted “Figure‐of‐eight” shaped per‐hydroxylated OH‐ExR4 ). Notably, demonstrates exceptional adsorption capability toward I 3 − ions an aqueous solution, with rapid kinetic rate 1.18×10 −2 g ⋅ mg −1 min . Furthermore, shows excellent recyclability potential as stationary phase column setups. discovery opens up avenues constructing macrocycles inspires further research functional materials water pollutant removal.

The development of artificial receptors that combine ultrahigh-affinity binding and controllable release for active guests holds significant importance in biomedical applications. On one hand, a complex with an exceedingly high affinity can resist unwanted dissociation induced by dilution effect interferents within physiological environments. the other stimulus-responsive guest is essential precisely activating its function. In this context, we expanded hydrophobic cavity surface hypoxia-responsive azocalix[4]arene, affording Naph-SAC4A. This modification significantly enhanced aqueous to 10

Abstract Clusterization‐triggered emissive (CTE) materials have attracted great attention in recent years. The regulation of the emission property with CTE through supramolecular interactions is an excellent strategy for construction smart fluorescent materials.
