Functionalization of multiwalled carbon nanotubes and their pH-responsive hydrogels with amyloid fibrils

Abstract:
New biocompatible, pH-responsive, and fully fibrous hydrogels have been prepared based on amyloid fibrils hybridized and gelled by functionalized multiwalled carbon nanotubes (MWNTs) far below the gelling concentration of amyloid fibrils. Sulfonic functional groups were introduced on the surfaces of MWNTs either by a covalent diazonium reaction or by physical π-π interactions. The presence of the isoelectric point of amyloid fibrils allows a reversible gelling behavior through ionic interactions with functionalized MWNTs.
