Complex photonic response reveals three-dimensional self-organization of structural coloured bacterial colonies..

Vivid colors found in living organisms are often the result of scattering from hierarchical nanostructures, where the interplay between order and disorder in their packing defines visual appearance. In the case of Flavobacterium IR1, the complex arrangement of the cells in polycrystalline three-dimensional lattices is found to be a distinctive fingerprint of the colony organization. By combining analytical analysis of the angle-resolved scattering response of in-vivo bacterial colonies with numerical modeling, we show that we can access the inter-cells distance and cell diameter with a resolution below 10 nm, far better than what can be achieved with conventional electron microscopy, suffering from preparation artifacts. Retrieving the role of disorder at different length scales from the salient features in the scattering response enables a precise understanding of the structural organization of the bacteria.
