Effect of Surfaces on Amyloid Fibril Formation
Abstract
Using atomic force microscopy (AFM) we investigated the interaction of amyloid beta (Ab) (1 42) peptide with chemically modified surfaces in order to better understand the mechanism of amyloid toxicity, which involves interaction of amyloid with cell membrane surfaces. We compared the structure and density of Ab fibrils on positively and negatively charged as well as hydrophobic chemically modified surfaces at physiologically relevant conditions.
