Description of research relevant to the action : 

Structure of biomaterials (plants). This research area covers imaging and analysis of structure at full scale: from nano to macro. Devices and methods completed are devoted to analysis of biomaterials as close as possible to the natural environment. The multiscale structure analysis consists of single polysaccharide structure, cell wall topography, size and orientation of cells and intercellular spaces, and tissue macromorphology. At present, the following techniques are used for structure evaluation: atomic force microscopy AFM, confocal scanning laser microscopy CSLM, Raman microspectroscopy, macroscopy, etc. Analysis of the structure is based on image analysis methods to extract the quantitative data from pictures.

Plant biomechanics. This research area covers mechanical testing of plants preformed at various scales. At nanoscale, AFM force-related techniques such as force spectroscopy, force volume or PeakForce Tapping™ are used. At microscale, mechanical testing is performed with a microtester integrated with an imaging system. Macromechanical testing is performed with a universal testing machine integrated with acoustic emission to monitor the fracturing of samples.

Biomechanical modelling. This research area covers modelling of the mechanical properties of plant tissues. The Finite Element Method (FEM) is used to predict the force-deformation curve from real images of plant structure and to obtain stress distribution within tissue. This research also aims to model at the molecular level with the use of quantum chemistry which models a single biomolecule and its reaction to a mechanical force.

Quality evaluation of fruits and vegetables. This activity is focused on the development and evaluation of new instrumental techniques for quality testing of perishable fruits and vegetables. The evaluation criteria consider both consumer and industry demands. Both approaches: destructive, such as mechanical testing with acoustic emission, and non-destructive, such as optical methods, are considered as useful for food quality evaluation.
