Two different functionalized nanoparticles: citrate-stabilized and lipid-coated magnetic nanoparticles were used for the formation of dehydropeptide-based supramolecular magnetogels consisting of the ultra-short hydrogelator Cbz-L-Met-Z-ΔPheOH. While the lipid-coated nanoparticles were distributed along the hydrogel fibers, the citrate-stabilized nanoparticles were aggregated upon gelation, which resulted in different heating efficiency.
