Biomass Depolymerization programs
Chemical Imaging of Plant Biomass with Micro- and Nano-Raman Spectroscopy - Completed
The program sought to understand the three-dimensional structure of the plant cell wall using established and novel Raman imaging methods to generate a high-resolution (300nm, then 30nm) chemical map of plant cell walls from different sources. This helped researchers visualize the chemical and physical obstacles to breakdown, which can help improve pretreatment procedures and identify plant material that may naturally be better suited to use in such processes.
The group used experimental and chemometric methods to perform the first analysis of the green plant Arabidopsis. At the same time they developed new technology, based on plasmonic antennas, to perform Raman imaging at the nano-scale. They demonstrated that this can be used to image carbon nanotubes, a nano-structure, at high (< 30 nm) resolution.
