This study fabricates a biocompatible bovine serum albumin (BSA)–coated gadolinium oxide nanoparticle carrier (Gd2O3@BSA) for curcumin (CUR) delivery and evaluates physicochemical properties and anticancer potential against nasal squamous cell carcinoma. Gd2O3@BSA-CUR forms ~26 nm spheres with zeta-potential around −36 mV and high CUR loading. Sustained, pH-dependent CUR release is observed, with excellent biosafety toward HFF2 normal cells and strongest anticancer activity versus RPMI 2650 and CNE-1 cells.

In this case, nanomedicine has emerged as an effective tool to address these drawbacks. Herein, a biocompatible carrier based on bovine serum albumin (BSA) coated gadolinium oxide nanoparticles (Gd2O3@BSA) was fabricated for curcumin (CUR) delivery and its physicochemical features along with its potential anticancer activity against nasal squamous cell carcinoma were also investigated. It was found that the fabricated Gd2O3@BSA containing CUR (Gd2O3@BSA-CUR) had spherical morphology with hydrodynamic size of nearly 26 nm, zeta-potential of-36 mV and high drug (CUR) loading capacity. Drug release profile disclosed that the release of CUR from the prepared Gd2O3@BSA-CUR nanoparticles occurred in a sustained-and pH-dependent manner. Also, in vitro cytotoxicity analysis revealed that the fabricated Gd2O3@BSA nanoparticles possessed excellent biosafety toward HFF2 normal cells, while Gd2O3@BSA-CUR appeared to display the greatest anticancer potential against RPMI 2650 and CNE-1 cancer cell lines. The results also show that the Gd2O3@BSA nanoparticles were compatible with the blood cells with minor hemolytic effect (\u003C 3%) . The manufactured NPs were found to be completely safe for biological applications in an in vivo subacute toxicity study. Taken together, these finding substantiate the potential anticancer activity of Gd2O3@BSA-CUR nanoparticles against nasal squamous cell carcinoma, but the results obtained demand further studies to assess their full potential.  \nKeywords Gadolinium oxide, Albumin, Curcumin, Nanoparticles, Nasopharyngeal carcinoma, Drug delivery  \n*Correspondence: Bo Kou  \n[evankbo@proton. me](evankbo@proton. me); [evankbo@outlook.com](evankbo@outlook.com)  \n1Department of Otorhinolaryngology head and neck surgery, The First Affiliated Hospital of Xi’an Jiaotong University, Xi’an 710061, Shaanxi, China  \n2Department of Otorhinolaryngology head and neck surgery, The Second Affiliated Hospital of Xi ’an Medical University, Xi’an 710000, Shaanxi, China  \n© The Author(s) 2024.
