Research background and current research topics

In our work on biomimetic materials we take inspiration from biology for solutions related to materials science and engineering related problems. There are several examples of phenomena found in biology that we can take inspiration form, such as tough and strong materials, superhydrophobic surfaces, adhesion, lubrication and processes by which materials components organize themselves into structures.

In many cases we take a molecular approach and try to link macroscopic effects to the structure and functions of molecules or other nanoscale components. For this, essential tools come from molecular biology, especially engineering of proteins by recombinant DNA techniques. Other building blocks that we work with are for example nanofibrillated cellulose and graphene.

The production and use of recombinant proteins for nanomaterials is a major challenge that we are pursuing. In this effort we have found a group of proteins called hydrophobins very useful. Hydrophobins are adhesive proteins that are found in filamentous fungi and show very useful self-assembling properties. The large expertise at VTT related to protein production is a crucial support to these activities.

Surface biotechnology with its methods such as AFM, electron microscopy, Langmuir trough, surface energy measurements, and colloidal techniques are an essential part of our research on biomimetics.
