PH-Responsive Cellulose/Silk/Fe₃O₄ Hydrogel Microbeads Designed for Biomedical Applications.

ABSTRACT: In this study, cellulose/Fe₃O₄ hydrogel microbeads were prepared through the sol-gel transition of a solvent-in-oil emulsion using various cellulose-dissolving solvents and soybean oil without surfactants. Particularly, 40% tetrabutylammonium hydroxide (TBAH) and 40% tetrabutylphosphonium hydroxide (TBPH) dissolved cellulose at room temperature and effectively dispersed Fe₃O₄, forming cellulose/Fe₃O₄ microbeads with an average diameter of ~15 µm. Additionally, these solvents co-dissolved cellulose and silk, allowing for the manufacture of cellulose/silk/Fe₃O₄ hydrogel microbeads with altered surface characteristics. Owing to the negatively charged surface characteristics, the adsorption capacity of the
