Abstract
Aβ (31-35) peptide and control peptides as well as full length Aβ (1-40) and Aβ (1-42) peptides were labelled with luminescent CdSe/ZnS quantum dots (QDs) to observe the morphology of amyloid fibers. A comparison was made between QDs and an organic dye, namely Dansyl group, which showed that the QDs present a much better contrast for imaging than the organic dye.
