Hence, in this study, we focused on designing a polysulfone (PSf) hollow\u2010fiber membrane embedded with hydrophilic iron oxide nanoparticles (IONPs) for protein purification by means of ultrafiltration. Before membrane fabrication, the dispersion stability of the IONPs was enhanced by the addition of a stabilizer, namely, citric acid (CA). Next, PSf\u2013IONP\u2013CA nanocomposite hollow\u2010fiber membranes were prepared via a dry\u2013wet spinning process and then characterized in terms of their hydrophilicity and morphology. Ultrafiltration and adsorption experiments were then conducted with bovine serum albumin as a model protein. The results that an IONP\/CA weight ratio of 1:20 contributed to the most stable IONP dispersion.
