However, the poor hydrophilicity of most photosensitizers makes them difficult to enter the cells and also susceptible to aggregation-induced quenching in aqueous environment. In this study, we encapsulated protoporphyrin IX (PPIX) by nanostructured lipid carrier to obtain a water-soluble PPIX delivery system (NLC-PPIX). The nanoparticles exhibited high colloidal stability and good fluorescence emission. The generation of 1O2 from the NLC-PPIX was verified using 9,10-anthracenediyl-bis(methylene)dicarboxylic acid (ABDA) as 1O2 indicator. The 1O2 quantum yield of the NLC-PPIX in aqueous solution was calculated to be ∼9%. The flow cytometry and fluorescence imaging confirmed the uptake of NLC-PPIX by the A2058 cells and the generation of 1O2 inside the cells under light excitation. The in vitro cytotoxicity assay showed that the NLC-PPIX exerted no toxicity on the A2058 cells under dark conditions, while light irradiation triggered high phototoxicity. The cell viability of the A2058 cells was significantly decreased and the inhibition rate reached approximately 96% by treating the cells with 200 μg/mL NLC-PPIX and 420 nm light irradiation. The successful cancer cell uptake and PDT effect revealed the therapeutic promise of our drug delivery system.","PeriodicalId":15138,"journal":{"name":"Journal of Biomaterials Applications","volume":" ","pages":"8853282251336557"},"PeriodicalIF":2.3,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144006768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work systematically investigates the complex relationship between MBG composition and surfactant templating on structural evolution, in vitro bioactive response, resultant drug loading efficiency and release. A total of 12 samples of sol-gel-derived MBG were synthesized using cationic and non-ionic structure-directing agents (cetyltrimethylammonium bromide, Pluronic F127 and P123) while modulating the SiO2/CaO content, generating MBG with surface areas of 60-695 m2/g. Electron microscopy and nitrogen desorption studies verified the successful synthesis of the 12 ordered MBG formulations. Assessment of hydroxyapatite conversion kinetics via FTIR spectroscopy and SEM demonstrated accelerated deposition for 70-80% SiO2 formulations, independent of the surfactant used. However, the templating agent had an impact on drug loading as observed in this study where MBG synthesized by the templating agent Pluronic P123 had higher drug loading compared to the other surfactants. To determine the drug release mechanisms, the in vitro kinetic profiles were fitted to various mathematical models including ze-ro. Most compositions exhibited release properties closest to zero-order, indicating a concentration-independent drug elution rate. These results in this study explain the relationship between tailored hierarchical architecture and intrinsic ion release rates to enable advanced functionality.","PeriodicalId":15138,"journal":{"name":"Journal of Biomaterials Applications","volume":" ","pages":"1064-1083"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11877986/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142949415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that the progression of neuronal loss begins early in fetal life, an early coverage of the defect is required to improve the neurological outcomes. Several studies have proposed patches as an alternative to full surgical repair, to achieve an early protection of the spine and possibly reduce the rate of complications of current prenatal surgical procedures. In our previous work, we developed a biocompatible, watertight and biodegradable patch to improve in utero MMC repair. This patch offers an anti-adhesive internal surface to prevent adhesion to spinal cord tissue, and a bioactive external surface to promote tissue coverage. The aim of this study is to assess the patch's in vitro degradation in an amniotic-fluid-like medium and investigate the surface functionalization effect, to understand its mechanism and predict the patch's behavior over time. The study was carried out for 24 weeks in FBS medium and after each period the samples were characterized by differential scanning calorimetry, scanning electron microscopy, steric exclusion chromatography, toluidine blue assay and contact angle measurement. The results revealed a progression of PCL hydrolysis over time, characterized by a decrease in molar mass and evidence of erosion as observed by SEM. Furthermore, this process appears to be accelerated by ozonation, compared to surface functionalization without ozonation. The latter can be considered as the most suitable technique to preserve the patch structure over time, while benefiting from the grafting polymers properties during the first weeks of implantation.","PeriodicalId":15138,"journal":{"name":"Journal of Biomaterials Applications","volume":" ","pages":"1097-1114"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143065883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The active ingredients of natural plants have aroused wide interest in the treatment of tumors. Triptolide shows toxic effects on a variety of epithelioid carcinoma cells. However, there is currently a lack of suitable delivery system for the treatment of ICC. In this study, organometallic framework material ZIF-8 was chosen to load TP, and then encapsuled in HSA micro-nanoparticles for the perfusion treatment of ICC. The results of SEM, XRD, and FTIR showed that ZIF-8 nanoparticles were encapsuled in HSA micro-nanoparticles. ZIF-8 nanoparticles (57.89 ± 12.24%) and TP@ZIF-8/HSA (36.8 ± 4.71%) micro-nanoparticles could significantly inhibited proliferation of RBE cell. Also, TP@ZIF-8/HSA micro-nanoparticles of all groups exhibited favorable cytocompatibility to L929 cells and hemocompatibility.
