It is featured by sustained inflammation, progressive periodontal tissue damage, and irreversible alveolar bone resorption, which remains a critical clinical challenge. In this study, a core–shell composite silk fibroin nanoparticle delivery system loaded with doxycycline (DOX) was successfully constructed. Firstly, ethanol-induced modification combined with silk fibroin self-assembly technology was applied to fabricate DOX-loaded silk fibroin microspheres. Based on electrostatic adsorption, layer-by-layer (LBL) self-assembly was further adopted to alternately adsorb chitosan (CS)-DOX and silk fibroin on the microsphere surface, thereby obtaining core–shell structured composite nanoparticles with a drug-loaded inner core. The as-prepared nanocarrier achieves favorable sustained drug release, antibacterial activity, and osteogenic potency. In vitro and in vivo experiments verified that the synthesized nanoparticles exhibit prominent antibacterial ability and favorable osteogenic activity, revealing great application potential. Compared with conventional periodontal treatment, this local targeted drug delivery strategy effectively overcomes the shortcomings of frequent administration and systemic side effects. Consequently, the DOX-loaded composite nanoparticles possess excellent clinical value and developmental prospects for targeted periodontitis therapy.</p></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"28 8","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148750945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional water treatment technologies often face limitations in selectivity, efficiency, and energy consumption, particularly when targeting trace level metal ions from complex aqueous matrices.

Nanomaterials offer high surface to volume ratios, tunable physicochemical characteristics, and multifunctional behavior, making them highly suitable for environmental remediation applications. In particular, their integration into membrane systems has led to significant improvements in separation performance. Nanoparticle-enabled membranes can be engineered through several strategies, including blending, in situ polymerization, nano-embedding, and surface coating. Among these, layer-by-layer (LbL) assembly has gained increasing attention due to its ability to precisely control film architecture at the nanoscale, enabling the design of highly selective and functional interfaces.

Bis(2-ethylhexyl) sulfosuccinate sodium salt (AOT) was used to form reverse micelles in a nonpolar medium, dodecane, which does not absorb microwave radiation. Reverse micelles containing an aqueous phase were dispersed in the oil phase, and these small polar droplets acted as nanoreactors. The aqueous phase contained citric acid and Tris base as reactants. Under microwave heating, only these microreactors absorbed microwave energy and were heated efficiently and homogeneously, facilitating the formation of carbon dots. The micelle size could be tuned by adjusting the water-to-surfactant molar ratio, producing carbon dots with uniform sizes ranging from 1.8 to 2.6 nm, depending on the AOT concentration. Transmission electron microscopy and photospectroscopy data were compared for carbon dots prepared using hydrothermal, domestic microwave-assisted, solvothermal reverse micelle, hexanoic-acid-based MARM, and dodecane-based MARM approaches. The characteristics of carbon dots produced using the proposed method were similar to those obtained using hydrothermal and domestic microwave-assisted methods.

The g-C₃N₄/MgO nanocomposite served as an efficient sensing interface owing to its large specific surface area, abundant active sites, excellent biocompatibility, and synergistically enhanced electron-transfer properties. The nanocomposite was immobilized on the electrode surface, followed by antibody attachment via a suitable cross-linking strategy and subsequent blocking of non-specific binding sites. The specific antigen–antibody interaction at the electrode surface resulted in a quantifiable decrease in the electrochemical signal as monitored by cyclic voltammetry.

Synthesis and functionalization strategies to enhance structural stability, adsorption capacity, and selectivity are critically discussed. Various composites incorporating graphene oxide, carbon nanotubes, biochar, polymers, and magnetic nanoparticles are analyzed, highlighting their synergistic effects in improving adsorption performance. Key operational factors influencing the adsorption process—such as solution pH, temperature, contact time, and adsorbent dosage—are systematically reviewed. Adsorption isotherms, kinetics, and thermodynamic parameters are assessed to elucidate the underlying mechanisms governing metal ion removal, including electrostatic interactions, complexation, and ion exchange. The regeneration and reusability of ZIF-67-based adsorbents are also evaluated, underscoring their practical potential for multiple adsorption cycles. Studies investigating the removal of heavy metals from real wastewater using ZIF-67 composites are examined, providing insights into real-world performance. Despite significant progress, challenges such as achieving consistent material stability, controlling pore structures, minimizing agglomeration, and developing cost-effective, scalable fabrication methods remain. Future research directions are proposed, focusing on the rational design of multifunctional composites, green synthesis strategies, and the integration of advanced modeling and characterization techniques.
