Barium titanate and its solid solutions hold significant potential for bone regeneration strategies. However, addressing the challenges related to biocompatibility, optimization, and manufacturing is essential before the possible clinical applications. This study focuses on barium strontium titanate (BST)-hydroxyapatite (HA) scaffolds as a potential bone growth enhancer. Ba0.5Sr0.5TiO3 is prepared by mixing the barium titanate and strontium titanate commercial nano powders and HA is synthesized using the sol–gel method, and BST-xHA composite samples are fabricated using conventional solid-state method. The samples are sintered at 1200–1300 °C, and the phase structure, microstructure, density, and electrical and mechanical properties are evaluated. Biological assessments, including MTT tests, are conducted. The electrical properties of composite samples improve, and the one with 20 wt% HA shows the highest amount of fracture toughness. Importantly, MTT assay results confirm the nontoxic nature of the BST-HA composite samples with the best OD value in BST-40 HA composite sample, making it a promising candidate for bone regeneration applications.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 10","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196262","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}

In order to address these issues with enzymes for real-world uses, biomimicry has become a viable method for creating highly effective biomimetic catalysts by imitating specific key features of enzymes. Regarding these biomimetic catalysts, metal–organic frameworks (MOFs) emerge as effective materials with tunable pore structures and functional groups which endow them to match certain enzymatic features, including structural features, active sites, microenvironments, assistant sites, and/or catalytic properties of enzymes.

To address these issues, this study employs a simple and green one-step synthesis method to prepare highly stable and well-dispersed spherical submicrometer copper particles with an average size of ≈140 nm. In this article, nontoxic polyvinylpyrrolidone and ethylene glycol (EG) act as reducing agents, while polyvinyl pyrrolidone (PVP) also serves as a capping agent and sodium hydroxide functions as a pH regulator. Utilizing the multifunctional properties of these materials, the method reduces the variety of additives required, simplifies the synthesis process, and lowers production costs. Finally, the mechanism of the one-step synthesis of submicrometer copper particles is discussed, which primarily relies on the reduction of copper ions by PVP and EG under alkaline conditions to form spherical submicrometer copper particles.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 10","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197344","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}

In this study, Co4N nanoparticles anchored on porous carbon are fabricated using a water-soluble Na2SO4 template through urea-assisted pyrolysis, with precise control of the calcination temperature for the Co@C precursor. The resulting Co4N@C composite, featuring Co4N nanoparticles as the primary active centers, exhibits high performance in peroxymonosulfate activation for tetracycline (TC) degradation, achieving a degradation rate exceeding 90% within 15 min. The magnetic properties of Co4N@C facilitate its easy separation from the reaction medium, and the recovered catalyst demonstrates only a slight decline in removal efficiency observed over five consecutive cycles. Quenching and electron paramagnetic resonance tests reveal that the degradation pathways involve both free radicals and nonfree radicals, with the electron transfer mechanism predominantly occurring in the nonradical pathway. Three degradation pathways are proposed based on the documentation of intermediate products from TC decomposition. The toxicity assessment of these intermediates and the original TC indicates a reduction in phytotoxicity of the degraded TC solution using the Co4N@C/PNS system.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102376","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}

This unique morphology enables a broader detection range for various analyte molecules through the local surface plasmon resonance effect, spanning from the visible to the near-infrared region. However, synthesizing gold nanostars (AuNSs) necessitates strict control over reaction conditions, along with specific reducing and structure-directing agents, which often results only in the formation of star-like structures with short branches. This research introduces an alternative approach to traditional reducing agents and surfactants, such as ascorbic acid and cetyl trimethyl ammonium bromide. It details a modified seed-mediated method for efficiently synthesizing AuNSs with a very small core (≈25 ± 5 nm) and elongated branches (h-AuNSs) with a length growth of ≈115 ± 8 nm, employing gallic acid as the reducing agent and Triton X-100 as the surfactant. This method produce high-quality, reproducible long-branch AuNSs for SERS substrates for detecting trace organic dye, crystal violet, detection limits of 11.76 ppm and quantification limits of 35.65 ppm. Moreover, the prepared h-AuNSs shows excellent reproducibility with only 4.58% variability across 20 points at 40 ppm.

However, the deficiency of L-cysteine within the body is associated with severe diseases like cancer, rheumatoid arthritis, and Alzheimer's. Conventional L-cysteine detection methods inherit limitations in accuracy and cost. In this research, a highly sensitive and specific colorimetric assay is developed using biogenic palladium nanoparticles (PdNPs). The biogenic PdNPs exhibite peroxidase mimetic activity, which oxidizes 3,3′,5,5′-tetramethylbenzidine in the presence of hydrogen peroxide (H2O2). The catalytic activity is determined by Michaelis–Menten and Lineweaver–Burk plots, yielding a Km of 3.65 × 10−5 m, Vmax of 9.71 × 10−7 M s−1, and kcat of 2.37 × 10−4 s−1, with a catalytic efficiency (kcat/Km) of 6.493 M−1 s−1. The colorimetric assay exhibits a low limit of detection of 0.12 μM and a limit of quantification of 0.36 μM. Smartphone-based analysis enhances the method's efficiency for precise detection of L-cysteine. A smartphone-based method successfully detects L-cysteine in real samples, showing high precision and excellent recovery rates ranging from 99.41% to 106.65%. This developed technique overcomes the limitations of traditional methods, exhibiting strong potential for rapid and specific L-cysteine detection in future biosensing applications.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 10","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196953","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}
