Even the most advanced treatment approaches fails to reduce the mortality of breast cancer. The present work demonstrates biofabrication of silver (AgSA) and silver/zinc oxide (Ag/ZnOSA) nanoparticles and their cytotoxic potentiality on the human triple-negative breast cancer (TNBC) cells. The nanoparticles synthesized using <i>Sauropus androgynus (L.)</i> extract were analyzed for their surface and morphological properties through BET, PXRD, FESEM, EDS, and FTIR techniques. The results obtained confirmed the presence of agglomerated and spherical shaped AgSA and Ag/ZnOSA nanoparticles with size in the range of 25.32 to 47.42 nm. The in-vitro anticancer study accomplished using MDA-MB468 TNBC cells shown the augmented antiproliferative potentiality of Ag/ZnOSA nanoparticles in comparison to pure AgSA nanoparticles (60.35 ± 0.94 to 86.21 ± 0.23). Besides, the AO-EB dual staining method revealed apoptosis of TNBC cells at early stages. Moreover, the biocompatibility of synthesized nanoparticles was found to be up to 94.28 ± 0.001%. Also the nanoparticles exerted antioxidant activity with a radical quenching percentage up to 87.92 ± 0.001. This study is the first to report the biosynthesis of Ag/ZnO nanocomposites via S. androgynus and their potent cytotoxicity against TNBC cells, highlighting their potential as promising candidates for future anticancer nanotherapeutics.</p><h3>Graphical abstract</h3><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":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145143282","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}

The eco-friendly synthesis technique is an affordable and scalable route that competes with traditional synthesis routes that require toxic precursors and high-temperature conditions. The structural, morphological, and optical properties of the synthesised ZrO₂ NPs were characterised by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS), and photoluminescence (PL) analysis. XRD proved the existence of a monoclinic phase ZrO₂ with an average crystallite size of 21 nm. The direct band gap value has been determined to be 3.1 eV according to the UV-Vis DRS analysis that proves the photocatalytic potential of the material. SEM imaging revealed the surface morphology, further confirming the nanoscale features of the synthesised particles. The photocatalytic activity of ZrO₂ NPs was evaluated for the degradation of atrazine (ATZ), a persistent triazine herbicide, under UV light irradiation. Various experimental parameters, including catalyst dosage, atrazine concentration, pH, and the role of scavengers, were systematically investigated to understand their influence on degradation efficiency. Notably, ZrO₂ NPs degraded 91% of the atrazine in only 30 min using a catalyst load of 30 mg and an initial ATZ concentration of 5 ppm. The high degradation efficiency of the material makes it quite promising for use in environmental remediation applications. Beyond the photocatalysis application, the synthesized ZrO₂ NPs have demonstrated promising applicability in forensic science for latent fingerprint detection, hence showing their multi-functionality. The advantages of green synthesis, superior photocatalytic efficiency, and forensic applicability set this study apart from previous works, emphasising its novelty and potential for real-world 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":"145141913","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}

To enhance the efficacy and targeting of anti-tumor drugs, various drug delivery systems based on nanotechnology have emerged in recent years, which can effectively deliver anti-tumor drugs to tumor tissues through retention and permeability effects. Despite their considerable advantages in tumor treatment, these delivery systems also have certain limitations, such as unclear metabolic pathways and challenges in industrial production. Among them, liposomes, as a type of nanocarriers composed of phospholipids and cholesterol, not only possess a bilayer vesicle structure similar to biological membranes that provides good encapsulation capacity for both hydrophilic and lipophilic drugs, but also exhibit excellent biocompatibility and can mimic cell membranes biological properties. Thus, liposomes based drug delivery system have been widely applied in the field of tumor diagnosis and treatment. Especially, a series of environment-responsive liposomal drug delivery system have been developed based on specific tumor microenvironments. These systems can not only regulate the tumor microenvironment to achieve the cascade effect in tumor treatment, but also explore various synergistic treatment strategies, improving tumor treatment efficacy while reducing toxicity to the body. Based on this, this paper reviews and summarizes the advantages and disadvantages of liposomes as drug delivery system in tumor diagnosis and treatment and provides proposals for enhancing the biosafety of liposomes and promoting their clinical translation.</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":"145141920","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}

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 (R² = 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.
