摘要
Deposition of beta-amyloid fibrils within senile plaques in the brain is a major hallmark of Alzheimer's disease. In this study, atomic force microscopy (AFM) has been used to provide surface topographical data of beta-amyloid fibrillization as a function of pH. Alteration of pH has led to observed changes in fibril self-assembly rate, diameter and branching. These results suggest that pH has a profound affect on beta-amyloid self-assembly and surface morphology.
