The assessment of nanomechanical properties of a single amyloid fibril in a confined space provides important information for understanding the role of fibrils in a cell microenvironment.In this study,the structure and nanomechanical properties of different fibrils formed in water nanofilms on mica surface are carefully investigated by using the new atomic force microscopy imaging mode-peak force quantitative nanomechanics(PF-QNM).We find that two types of fibrils with different morphologies are formed in water nanofilm on mica.The compression elasticities of these two types of fibrils are 3.9±0.9 and 2.5±0.6GPa,respectively.The remarkable difference is possibly due to the structural discrepancy in two types of fibrils.
