中文摘要	The fine folding and assembling characteristics of amyloid beta (A beta) peptides are important to pharmaceutical studies of drug molecules and to the pathological analysis of neurodegenerative disorders such as Alzheimer's disease at the molecular level. Here we present observations of the multiple folding characteristics of amyloid peptide A beta(42) lamellae using scanning tunneling microscopy. Molecularly resolved core regions of A beta(42) hairpins and unfolded peptide assembly structures are identified. The parallel assembling characteristics of A beta(42) hairpins can be confirmed in the study. In addition, single-molecule binding characteristics of Congo red and thioflavin T have been shown to bind at the groove regions of peptide assemblies. This Study demonstrates a complementary venue for studying molecular heterogeneity of peptide assemblies, as well as the binding characteristics of molecular modulators. (C) 2009 Elsevier Ltd.
