The sol-gel method was used for the synthesis of single and combined photocatalysts. To identify them, XRD, DRS, EDX, SEM, VSM, FT-IR and X-ray mapping methods were used.

The values for the Scherrer formula are 20.5, 25.2 and 14.8 nm for zinc ferrite, nickel ferrite and zinc-substituted nickel ferrite, respectively, and 27.3, 26.5 and 20.4 nm by the Williamson-Hall formula.

Furthermore, the nanoparticles exhibited substantial anti-cancer effects, with IC<sub>50</sub> values of 26.4 µg/mL against Caco-2 cells and 43.6 µg/mL against MCF-7 cells. This work advances green nanotechnology by integrating scientific innovation with environmental sustainability, thereby opening avenues for further research in materials science and biomedical applications.</div></div>","PeriodicalId":9758,"journal":{"name":"Chemical Physics Impact","volume":"11 ","pages":"Article 100954"},"PeriodicalIF":4.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145358184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
