Redox-triggered changes in the self-assembly of a ferrocene-peptide conjugate

Redox-triggered changes in the self-assembly of a ferrocene-peptide conjugate

Ultrasonication of a ferrocene conjugate of a short amyloid peptide (Aβ18-20) in toluene causes formation of an organogel, which undergoes dramatic structural changes upon oxidation from a nanofibrillar network to spherical micelles. This morphological change is redox-controlled and reversible.
