An alternative approach to amyloid fibrils morphology: CdSe/ZnS quantum dots labelled beta-amyloid peptide fragments Abeta (31-35), Abeta (1-40) and Abeta (1-42)



An alternative approach to amyloid fibrils morphology: CdSe/ZnS quantum dots labelled beta-amyloid peptide fragments Abeta (31-35), Abeta (1-40) and Abeta (1-42)



Colloids and Surfaces. B Biointerfaces 50(2): 104-111



Abeta (31-35) peptide and control peptides as well as full length Abeta (1-40) and Abeta (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.
