Bacterial infections claim millions of lives every year, with the escalating menace microbial antibiotic resistance compounding this global crisis. Nanozymes, poised as prospective substitutes for antibiotics, present a significant frontier in antibacterial therapy, yet their precise enzymatic origins remain elusive. With continuous development nanozymes, applications elemental N-modulated nanozymes have spanned multiple fields, including sensing and detection, infection cancer treatment, pollutant degradation. The introduction nitrogen into not only broadens application range but also holds importance design catalysts biomedical research. synergistic interplay between W N induces pivotal alterations electronic configurations, endowing tungsten nitride (WN) peroxidase-like functionality. Furthermore, vacancies augments nanozyme activity, thus amplifying catalytic potential WN nanostructures. Rigorous theoretical modeling empirical validation corroborate genesis enzyme activity. meticulously engineered nanoflower architecture exhibits an exceptional ability traversing bacterial surfaces, exerting potent bactericidal effects through direct physical interactions. Additionally, topological intricacies these nanostructures facilitate targeting generated radicals on culminating efficacy against both Gram-negative Gram-positive strains along notable inhibition biofilm formation. Importantly, assessments using skin model underscore proficiency nanoflowers effectively clearing fostering wound healing. This pioneering research illuminates realm pseudoenzyme activity capture-killing strategies, promising fertile ground innovative, high-performance artificial peroxidases.

The stratum corneum of the skin functions as a barrier, obstructing drug absorption and complicating treatment infections caused by pathogens such bacteria, fungi, viruses through topical methods. In this research, microneedle patch was developed, which consists gelatin-sucrose (SG) that encapsulates polydopamine-copper nanoparticles (PDA@Cu) at tip for antibacterial purposes. Poly(ethylene glycol) diacrylate (PEGDA) served primary substrate shaft (PDA@Cu-SG/PEGDA). This engineered to enhance permeability facilitate efficient delivery drugs rapid dissolution tips. Coordinate bonds can be formed between PDA Cu ions, resulting in immobilization particles on surface, aids green synthesis PDA@Cu photothermal particles. SG polymer, contained PDA@Cu, employed fill cavities series centrifugation steps. Subsequently, UV-induced polymerization carried out produce PEGDA microneedles with hydrophilic tips Furthermore, physicochemical characteristics polymer microneedles, including morphology, composition, mechanical strength, were thoroughly characterized. These demonstrated sufficient strength. Owing ability disrupt bacterial membranes, excellent vitro efficacy. We validated activity against Escherichia coli Staphylococcus aureus conducting plate coating assays. results assays indicated minimally invasive strategy achieved broad-spectrum effects; thus, may suitable approach managing polymicrobial during clinical trials.
