摘要
(Figure Presented) Hold them or fold them: The morphology of aggregated amyloid-β depends on the concentration of Cu2+ ions, as shown in the TEM images. Distinct differences in the coordination of Cu2+ ions to amyloid-β are observed by electron spin resonance as the metal concentration increases. The results suggest a correlation between specific Cu2+ ion coordination and the overall morphology of aggregates. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
