Fabrication of sisal fiber-derived beads from sustainable solvents: investigating their potential for pH-responsive sorption of bovine serum albumin
Gel beads were prepared from sisal fibers (SFs) by dissolving the treated biomass in green solvent systems (NaOH–urea and ZnCl2 aqueous solutions), followed by regeneration in different coagulation media (HNO3, CaCl2, and ethanol). This sustainable strategy converts renewable sisal biomass into functional bio-based mat...
