First nanodiffraction experiment using KB-mirror at Nanofocus Endstation

2D map of oriented cellulose content in the different cell wall layers, each pixel corresponds to 500nm.

Data recorded within the first nanodiffraction experiments on single wood cells in collaboration with Selina Storm (HZG) documents the high spatial resolution of the nanobeam generated with the KB-mirror optics at the Nanofocus endstation and its applicability to weakly scattering, biological systems: 2D-scanning-nanodiffraction with a step size of 500 nm was performed over thin (10µm) sections of spruce wood in order to map the crystalline fraction of cellulose and its local orientation in the plant’s cell walls.
