CD BioSciences has many years of successful experience in the field of characterization of the mechanical properties of cell walls. We are committed to building a platform based on nanoindentation technology to provide our customers with a comprehensive range of services for measuring the properties of wood cell walls.
Wood cells have a complex multi-component structure and their structural arrangement is one of the most important factors affecting their mechanical properties. It is well known that the cell wall consists of a primary wall, a secondary wall and a middle lamella. Typically, the secondary wall is made up of a narrow outer layer (layer S1), a very thin and narrow inner layer (layer S3) and an intermediate layer (layer S2). Measuring mechanical properties at the fibre or cell wall level is a challenge due to the complexity of the cell wall structure as well as biological variation.
Nanoindentation is a new technique capable of characterizing the mechanical properties of the cell wall at the nanoscale. It allows access to the mechanical properties within the cell wall layers and reduces modifications to a minimum. The technique has been used to estimate the indentation modulus of mature natural or thermomechanically modified wood fibre cell walls. As an effective experimental method, it can also help to validate other theoretical simulations, such as rheological models and assumptions about the structure of the cell wall.
