01 / Application needs

A nanoscale microfibril network provides the structural basis for professional materials

Cellulose microfibrils are formed from glucose units linked by β-1,4-glycosidic bonds and have an approximate diameter of 20–40 nm. Their high aspect ratio allows them to interweave in the liquid phase and form a continuous three-dimensional network.

Dynamic fermentation is used to prepare fibre materials, while precision membrane fermentation forms continuous membrane substrates during cultivation and can introduce functional ingredients for the target system. Material purity, porosity, liquid-holding capacity and loading method should be evaluated separately for professional care, wound dressings or delivery applications.

02 / Material roles

Define the key tasks within the target system

Nanoscale microfibril structure

Microfibrils measuring 20–40 nm combine a high aspect ratio and surface area to construct porous three-dimensional networks.

Precision membrane fermentation

Continuous bio-cellulose membranes form during cultivation and are evaluated for purity, porosity, fit and liquid retention.

Loading and delivery research

The three-dimensional network can be studied for loading and release of proteins, lipid vesicles and other ingredients, with suitability verified for the intended ingredient and use method.
