Using a green phytochemical approach, the stability, functionalization, and nanoscale characteristics of these Green CuO NPs were investigated using UV-Vis spectroscopy, FTIR, TEM, and zeta potential measurement.

This study aimed to optimize the doxycycline hyclate Aloe emodin-loaded nanostructured lipid carriers (DH-AE NLCs) approach and assess their therapeutic potential in diabetic wound healing. Different formulation variables were optimized to get the desired particle size, zeta potential, Polydispersity index (PDI), and entrapment efficiency. The diabetic wound healing potential of the formulated system was performed by In-vitro anti-microbial assay and in-vivo studies in rats and validated by histopathological analysis. The optimized formulation has a particle size of 165.32 nm, Zeta potential − 28.2, PDI 0.236, and entrapment efficiency of 79.99 %. X-ray diffraction and differential scanning calorimetry revealed that both APIs were amorphous in the DH-AE NLCs. In-vitro drug release studies showed a sustained release pattern over 24 h and followed the Higuchi model (R<sup>2</sup> = 0.98) release kinetics. The antimicrobial activity demonstrated significant inhibition against gram-positive and gram-negative bacteria. In-vivo anti-diabetic studies revealed a significant decrease in blood sugar levels in diabetic rats treated with the DH-AE NLCs formulation, achieving a 65% reduction after 14 days compared to 20% in the pure drug group. Histopathological analysis of skin tissues validated these findings, showing improvement in histopathological changes in damaged skin cells after treatment with gel. From the above findings, it concluded that the optimized DH-AE NLCs formulation has promising physicochemical stability, sustained drug release, enhanced antimicrobial activity, and found therapeutically effective in diabetic wound healing even more than the marketed formulation.

The probe exhibited a strong emission peak at 712 nm under excitation at 330 nm. Interestingly, the addition of melamine alone did not alter the fluorescence emission of DAC@Cu NCs, indicating the necessity of an intermediate quencher for effective detection. To address this, Hg²⁺ ions were employed as a quencher, effectively reducing the fluorescence emission of DAC@Cu NCs through a static quenching mechanism. Upon introducing melamine, coordination between melamine and Hg²⁺ resulted in the removal of Hg²⁺ from the probe’s surface, restoring its fluorescence emission. Under optimized conditions, the ratio of fluorescence intensity before (F<sup>0</sup>) and after the addition of melamine (F) exhibited a linear relationship with melamine concentration over the range of 0.01–110 µM, with an impressive limit of detection (LOD, S/<i>N</i> = 3) of 0.0015 µM. The system demonstrated excellent selectivity for melamine detection, even in the presence of amine-containing compounds, confirming its robustness. Furthermore, the DAC@Cu NCs + Hg²⁺ system was successfully applied to real-world samples, including infant formula and commercial milk, achieving recovery rates of 98.7–103.5% with relative standard deviations (RSDs) between 2.43% and 3.78%. These findings highlight the practical utility of the proposed probe for rapid, accurate, and cost-effective melamine detection.

Alopecia, lacking a definitive cure, necessitates the development of novel approaches to address hair follicle-related disorders. The application of metal nanoparticles as nanocarriers has emerged as a promising strategy for treating alopecia, gaining considerable attention in recent years. Metal nanoparticles, including iron, zinc, gold, silver, copper, and molybdenum, not only enhance targeted drug delivery to hair follicles but also promote follicular proliferation, maintain scalp hygiene, facilitate wound healing, improve blood circulation, and offer innovative therapeutic solutions for alopecia. Furthermore, these nanoparticles exhibit antioxidant properties and modulate gene expression associated with alopecia, leveraging their dual effects of scavenging reactive oxygen species and remodeling microvasculature. This review comprehensively explores the efficacy of metal nanoparticles and metal chelates in treating alopecia, elucidating their mechanisms in promoting hair regrowth. It also evaluates various experimental methodologies, including permeation studies targeting hair follicles, advanced imaging techniques to assess nanoparticle penetration, in vitro cell line studies, and in vivo animal models. Additionally, the review highlights regulatory considerations, patent landscapes, toxicity profiles, and potential clinical applications of metal nanoparticles in alopecia treatment and hair regeneration. Notably, few articles have provided an integrated analysis covering all these critical aspects, hence making this review a valuable resource for researchers and clinicians seeking innovative solutions for alopecia management.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":618,"journal":{"name":"Journal of Cluster Science","volume":"36 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10876-025-02841-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ZnO NPs exhibited effective antibacterial activity against <i>Staphylococcus aureus</i>,<i> Listeria monocytogenes</i>,<i> Salmonella enteritidis</i>, and <i>Escherichia coli</i> with minimum inhibitory concentrations (MIC) of 137.5 µg/mL, 135.4 µg/mL, 137.7 µg/mL, and 185.2 µg/mL, respectively. Additionally, the ZnO NPs demonstrated antidiabetic activity by effectively inhibiting α-amylase, an enzyme involved in carbohydrate digestion, with an IC<sub>50</sub> value of 2.355 mg/mL. Moreover, the ZnO NPs exhibited significant degradation of methylene blue (MB) dye, achieving a 95.5% degradation efficiency within 120 min under UV irradiation. These results suggest that phytogenically synthesized ZnO NPs using black chokeberry fruit extract have great promise for degrading environmental pollutants and may be valuable in various biomedical applications, including antioxidant, antibacterial, and antidiabetic therapies.</p></div>","PeriodicalId":618,"journal":{"name":"Journal of Cluster Science","volume":"36 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10876-025-02830-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Apigenin (APG), a flavonoid derived from natural sources, displays promising anti-cancer effects, but its effectiveness is limited by its low solubility and bioavailability. This study aimed to develop and evaluate chitosan-coated PLGA nanoparticles (CS-PLGA NPs) for enhanced delivery and efficacy of APG against breast cancer cells. CS-PLGA NPs loaded with APG were synthesized and characterized by size, surface charge, drug loading, and release profile. Subsequently, their cytotoxicity against SKBR3 breast cancer cells was compared to free APG. APG-CS-PLGA NPs exhibited the desired characteristics (size ~ 170 nm, positive zeta potential, high encapsulation efficiency 98.7%) and displayed a sustained APG release profile. Release results in gastrointestinal conditions suggest that PLGA-CS nanoparticles are promising for oral apigenin (APG) administration, as they retain most of the drug content. Notably, these nanoparticles significantly enhanced APG cytotoxicity toward SKBR3 cells compared to free APG (IC50: 67.1 vs. 151.5 µg/mL), indicating improved cellular uptake and efficacy. This study demonstrates the successful development of CS-PLGA NPs as a promising platform for targeted APG delivery with enhanced anticancer activity against breast cancer cells. Further investigations are warranted to explore in vivo efficacy and optimize the system for clinical applications.</p></div>","PeriodicalId":618,"journal":{"name":"Journal of Cluster Science","volume":"36 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
