However, its antibacterial efficacy under visible light still remains limited. To develop low-cost and biocompatible antibacterial materials, this article provides a facile method for in situ preparation of a trace amount of silver (Ag) doped TiO2 nanorods (TiO2NR–Ag) composites, which cannot only enhance the antibacterial properties under visible light, but also has good biocompatibility. Two representative epidemic strains, Staphylococcus aureus and Escherichia coli, are selected for analysis of the antibacterial properties of the obtained TiO2NR–Ag composite nanoparticles. The results demonstrate that even if the Ag doping level is as low as 2.5 × 10−4 wt% (i.e., Ag/TiO2 = 2.50 µg g−1), the TiO2NR–Ag composite nanoparticle coatings are transparent and exhibit exceptional antibacterial properties, which is attributed to synergistic enhanced bactericidal effect of the active substances generated by TiO2NR–Ag under visible light. The cytotoxicity and hemolysis rate results indicate that TiO2NR–Ag composite exhibit excellent biocompatibility. This study effectively improves the antibacterial effect of TiO2 photocatalytic nanomaterials while maintaining their biocompatibility, and the prepared TiO2NR–Ag composite nanoparticles can be applied in various fields such as window glasses, medical device surfaces, furniture surfaces, and optical devices, etc.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"70 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140301543","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}

The ZnO-NPs are produced through a sintering process at temperatures ranging from 300 to 700 °C. The most effective nanoparticles are obtained at 600 °C, as determined by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) analyses, which confirmed their crystallinity and purity. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) are employed to characterize the size and shape of the nanoparticles, revealing predominantly spherical and hexagonal structures with stable dimensions. The cytotoxic effects of the Cs/ZnO-NPs are evaluated against various cancer cell types. The results show that at a concentration of 125 µg mL−1, the Cs/ZnO-NPs demonstrate significantly higher cancer cell toxicity compared to ZnO-NPs alone, while remaining non-toxic to normal cells. This indicates that Cs/ZnO-NPs have a superior ability to selectively target cancer cells.

In order to regulate the corrosion inhibition performance of A-NBs, the particle characteristics of A-NBs in flowing composite salt solutions are investigated, and the corrosion inhibition effect of A-NBs under different concentration ratios and rotational speed of simulated circulating cooling water is studied. High salt concentrations significantly reduced the particle size, concentration, and zeta-potential value of A-NBs, thus reducing the stability of A-NBs. The flow velocity has a slight effect on A-NBs. The results of the weight loss and electrochemical method showed that A-NBs achieved the highest corrosion inhibition rate of 55% under a concentration ratio of 1.5 and a rotational speed of 100 r min−1. The surface characterization of brass specimens revealed that A-NBs facilitated the formation of Cu2(OH)2CO3 passivation film, calcium carbonate scale film, and a layer of bubbles on the surface of brass, which subsequently mitigated the erosive impact of the fluid. A-NBs can adsorb cations and thus reduce the concentration of corrosive ions. However, the increase in concentration ratio and rotational speed impeded the formation of the bubble layer and passivation film.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"27 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140301362","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}

The goal of this work is to synthesize SPIONs for biomedical applications (for example as a contrast agent for the MRI): SPIONs should be stable in an aqueous media, monodisperse, and have good crystallinity and magnetic properties. To achieve this result, a microwave process is carried out. However, any study describes the microwave parameter on the synthesis of the nanoparticles. This work offers to determine the best conditions of the microwave to obtain ideal SPIONs for MRI. For this, an experimental design is carried out to determine these parameters thanks to different techniques of characterization (Transmission Electronic Microscopy, Dynamic Light Scattering, X-ray diffraction, Thermogravimetric Analysis, magnetic characterizations).

Nanoparticle‐based drug delivery systems (DDS) can improve cancer immunotherapy through site‐specific delivery and controlled release of immunotherapeutics in the tumor microenvironment (TME). However, DDS face several challenges, including unspecific release. To address this, vaterite nanoparticles (VNPs) that selectively release immunotherapeutic proteins at low pH conditions find in the TME, are established previously. In the current study, these VNPs are further modified for active targeting without affecting the loaded protein activity, exemplified with Tumor Necrosis Factor α (TNF). Specifically, VNPs are coated with gelatin, a matrix‐metalloprotease sensitive polymer which provides functional groups for further conjugation. Subsequently, streptavidin is covalently linked to the gelatin shell by amine‐epoxy chemistry, enabling coupling of any biotinylated ligand. Exemplified by biotinylated cetuximab and rituximab, targeted VNPs selectively bind to cells expressing epidermal growth factor receptor (EGFR) or CD20, respectively. Importantly, TNF remains functionally active after the modification steps, as VNP treatment increased ICAM‐1 expression on FaDu cells and activated NFκB signaling in a Jurkat.NFκB‐luciferase cell line model. In conclusion, a targetable vaterite‐based DDS is produced that allows for easy surface modification with any biotinylated ligand that may find broad applications in tumor‐selective immunotherapy.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"35 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140129570","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}

Topical route of administration offers benefits over other routes such as avoidance of first‐pass metabolism, low dose, longer residence time, and absence of off‐target delivery. Skin serves as a mechanical barrier for therapeutic delivery with selectively permeable essential molecules. Considering the structural complexity of skin, delivery of therapeutics at targeted site requires sophisticated method such as nanotechnology‐assisted therapeutic delivery. The roadmap for combinatorial approach of nanotechnology and skin therapeutics has proven significant in clinical and marketed products. Currently, various pharmaceutical aids such as nanocrystal (NCs), nanoparticles, nanoemulsion, nano‐micelles, nano lipidic carriers, and hybrid nanocarriers are currently in market. Among all the other nanocarriers, nanocrystal offers precedence over other nanocarriers due to its facile method of preparation, reproducibility, low excipient concentration, and high therapeutic loading capacity. The recent literature data suggest the breakthrough evolution of NCs in topical therapeutic delivery.

The morphology, particle size, and crystal type of CaCO3 are characterized via transmission electron microscopy, X-ray diffraction, nanoparticle size, and zeta potentiometer. The creation of core–shell calcium carbonate nanoparticles is examined in relation to reaction circumstances (i.e., additive sequence, additive amount, and additive mixing time), carbonization temperature, liquid flow rate, and templates with varying chain lengths. Furthermore, a discussion is held regarding the formation mechanism of spherical core–shell calcium carbonate that is created using the innovative template carbonization method. The results show that the order, amount, liquid flow rate, and template type of additives have a significant effect on the crystal shape of calcium carbonate nanoparticles. The mixing time of additives has a significant effect on the particle size of calcium carbonate nanoparticles. Interestingly, the thickness of the shell depends on the carbonization temperature, and too slow or too fast flow rate will lead to the formation of cyclic calcium carbonate nanoparticles.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":"32 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139968053","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}
