Atomic force microscopy stiffness tomography on living Arabidopsis thaliana cells reveals the mechanical properties of surface and deep cell-wall layers during growth.
Cell-wall mechanical properties play a key role in the growth and the protection of plants. However, little is known about genuine wall mechanical properties and their growth-related dynamics at… Expand
Quantification of compression wood severity in tracheids of Pinus radiata D. Don using confocal fluorescence imaging and spectral deconvolution.

Confocal fluorescence microscopy was used to examine the spectral characteristics of lignin autofluorescence in secondary cell walls of normal and compression wood from Pinus radiata. Using UV… Expand
Fluorescence lifetime imaging of lignin autofluorescence in normal and compression wood
Wood cell walls fluoresce as a result of UV and visible light excitation due to the presence of lignin. Fluorescence spectroscopy has revealed characteristic spectral differences in various wood… Expand
STRUCTURAL ORGANISATION OF THE WOOD POLYMERS IN THE WOOD FIBRE STRUCTURE
The organization of the major polymers in the wood fiber has a large impact on the properties of the structure. Numerous studies have been devoted to the cellulose microfibril arrangement, providing… Expand

Data on medical applications of cerium oxide nanoparticles CeO2 (CONP) are promising, yet information regarding their action in cells is incomplete and there are conflicting reports about in vitro… Expand
Probing the lignin nanomechanical properties and lignin–lignin interactions using the atomic force microscopy
By combining atomic force microscopy (AFM) force and environmental scanning electron microscopies (ESEMs), herein we present an evidence for the existence of strong intermolecular forces, which are… Expand
Activities of Antioxidant Systems During Germination of Chenopodium rubrum Seeds
The activities of superoxide-dismutase (SOD), catalase (CAT) and peroxidase (POD), and concentrations of glutathione and ascorbate have been studied during the first stages of germination in… Expand
Topographical characterization and surface force spectroscopy of the photochemical lignin model compound.
By combining the results from atomic force microscopy (AFM) and environmental scanning electron microscopy (ESEM), herein we investigate properties of photochemical lignin model compounds. We provide… Expand
