The pathological microenvironment-characterized by bacterial infection, reactive oxygen species (ROS) accumulation, persistent inflammation, and impaired tissue repair-severely impedes this process. In this work, we constructed a photothermally triggered, microenvironmental pH-regulating platinum nanozyme system, ACC@LPDAPt nanoparticles (NPs), leveraging the pH-dependent peroxidase-like and catalase-like activities of platinum nanozymes. This system achieves enzyme-like activity conversion by modulating the wound pH, thereby accomplishing bactericidal effects, ROS scavenging, anti-inflammation, and promoting wound healing. Our study demonstrates that ACC@LPDAPt NPs exhibit a pronounced photothermal effect and the ability to modulate the microenvironmental pH. Moreover, their excellent hemocompatibility and cytocompatibility promote cell proliferation and migration. In the inflammatory microenvironment, ACC@LPDAPt achieved inhibition rates of 99.8 ± 0.1 % for Staphylococcus aureus (S. aureus) and 99.9 ± 0.1 % for Escherichia coli. Furthermore, the photothermal-induced dissolution of amorphous calcium carbonate (ACC) raises the microenvironmental pH to neutral, endowing ACC@LPDAPt with robust ROS scavenging and oxygen production capabilities. This process promotes wound healing by reducing inflammation, stimulating cell proliferation and migration, granulation tissue formation, collagen deposition, and neovascularization, thereby significantly accelerating the healing of S. aureus-infected wounds with a closure rate of 97.3 ± 1.2 %. These multifunctional properties make ACC@LPDAPt NPs a promising nano-therapeutic strategy for bacterial-infected wounds.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"703 Pt 2","pages":"139299"},"PeriodicalIF":9.7,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145342438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although carbon coating can inhibit the oxidative passivation of nZVI in air, the deposition of iron ions on its surface during the reaction still leads to its rapid deactivation. In this study, crystalline boron was introduced as a novel co-catalyst to activate peroxydisulfate (PDS) in conjunction with carbon-coated nZVI (Fe0@C) for the degradation of tetracycline (TC). The results showed that the Boron/Fe0@C/PDS system achieved complete removal of TC within 1 min. Free radical scavenging and chemical probe experiments confirmed the generation of multiple reactive oxygen species, with singlet oxygen being primarily responsible for the degradation of TC. Mechanism investigations revealed that crystalline boron can accelerate the redox cycle of iron ions by donating electrons, thereby inhibiting the deposition of iron ions on the Fe0@C surface and achieving the stable release of ferrous ions and the continuous activation of PDS. Furthermore, crystalline boron gradually undergoes surface oxidation during the electron donation process, but its surface self-cleaning effect can continuously expose new active sites. The synergistic effect of crystalline boron and carbon coating prevents passivation of nZVI throughout its lifecycle, thereby ensuring excellent catalytic efficiency and long-term stability. This study provides a practical anti-passivation strategy and offers new insights into the rational design of nZVI-based AOPs.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"703 Pt 2","pages":"139310"},"PeriodicalIF":9.7,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145342429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dynamics is modelled by the molecular-kinetic theory (MKT) and the influence of chain entanglements on the relation between ζ and Mn is discussed.Findings: Two regimes are indeed observed for the contact line friction versus molecular weight and are modelled by ζ ∼ Mnδ with δ = 2.18 ± 0.27 for Mn < Mc and δ = 3.78 ± 0.51 for Mn > Mc. The solid-liquid interaction activation energy Δgs∗ is small ∼0.013 J/m2 regardless of Mn, as it is mainly controlled by the interfacial interaction between the PDMS chains and the fiber. In contrast, the viscous interaction activation energy Δgvis∗ presents a significant increase when Mn reaches Mc, with Δgvis∗ surpassing Δgs∗ up to 21.6 %.

Molecular simulations indicate that the photogenerated chlorine radical first mediates CH abstraction from the PET backbone to produce an alkyl radical. This radical then reacts with oxygen to generate a peroxy radical, which finally cleaves the low-energy ester CO bond, leading to depolymerization and the formation of terephthalic acid. The Ce4+/Ce3+ redox cycle further enhances radical generation, facilitating the catalytic process.
