WebJan 26, 2024 · Here, we developed a high-speed bimodal AFM that provided high-spatial resolution maps of the elastic modulus, the loss tangent, and the topography at imaging rates of 5 fps. The microscope was applied to identify the initial stages of the self-assembly of the collagen structures. WebFeb 24, 2024 · In Laurent’s early career his biggest success was to be able to resolve the collagen molecule – the height of which, measured with an AFM, is 0.5nm (vs say the size of DNA which is 10nm across a long filament). “The images I published back in 2005 were the first ever taken of collagen molecules by atomic force microscopy.
