Bioproduct Chemistry

The Bioproduct Chemistry group is led by Prof. Monika Österberg. The group works on the development of renewable, high added-value materials based on lignocellulosics. Our research is especially focused on understanding interfacial properties using atomic force microscopy (AFM, imaging and force measurements), quartz crystal microbalance with dissipation monitoring (QCM-D), and surface plasmon resonance (SPR), among other techniques.

Lignin valorization

An important part of our research is devoted to the transformation of waste lignin from biorefineries and pulp industries into high added-value products. The preparation, modification and utilization of colloidal lignin particles are at the core of this research line.

Bio-based coatings, adhesives, and composites are some examples of commercial applications of colloidal lignin particles we are working in.

Biocomposites

Aiming for a more sustainable use of natural resources, we work on the development of new composites based on cellulose nanofibrils, hemicelluloses, and colloidal lignin particles to replace fossil-oil based materials commonly used in packaging and other applications. Components from bark extracts are also studied for packaging and other added-value applications.

Sustainable modification of textiles

We explore different green approaches for the surface modification of textile fibres. The main aim is to develop bio-based dyes and pigments to replace synthetic dyes commonly used in the textile industry.

In addition, nontoxic approaches for (super)hydrophobic (that is, waterproof) and breathable textiles are explored.

Living cells and biomaterials

The interaction forces and adhesion between living cells and different biomaterials (including cellulose nanofibrils) have been studied in our group. Analyses on cell mechanics have also been carried out. The results of these studies are relevant for advanced cell cultures, wound treatment, drug testing, and tissue engineering, among other biomedical applications.

We also work on the development of 3D printed scaffolds made of hydrogel materials based on wood polymers for cell culturing and other biomedical applications.
