In situ plant materials hyperspectral imaging by multimodal scattering near-field optical microscopy
Abstract
Plant cells are elaborate three-dimensional polymer nano-constructs with complex chemistry. Here, multimodal scattering nearfield optical microscopy of poplar trees is used to establish in situ high-resolution mappings of the local dielectric functions and compositional distribution of lignin and cellulose in plant cell walls.
