Self-Assembling Peptide-Based Magnetogels for the Removal of Heavy Metals from Water.

ABSTRACT: In this study, we present the synthesis of a novel peptide-based magnetogel obtained through the encapsulation of γ-Fe₂O₃-polyacrylic acid (PAA) nanoparticles (γ-Fe₂O₃NPs) into a hydrogel matrix, used for enhancing the ability of the hydrogel to remove Cr(III), Co(II), and Ni(II) pollutants from water. Fmoc-Phe (Fluorenylmethoxycarbonyl-Phenylalanine) and diphenylalanine (Phe₂) were used as starting reagents for the hydrogelator (Fmoc-Phe₃) synthesis via an enzymatic method. The PAA-coated magnetic nanoparticles were synthesized in a separate step, using the co-precipitation method, and encapsulated into the peptide-based hydrogel. The resulting organic/inorganic hybrid system (γ-Fe₂O₃NPs-peptide
