Abstract
The present invention concerns a method and a device for determining mechanical stress load, and optionally interface effects, on particles dispersed in a fluid. According to the invention, fluid comprising dispersed particles such as biomolecules is fed into a sample space of a device comprising a jacket which encloses a sample chamber and at least two rolls arranged within said jacket such that said sample space is defined between said rolls, said rolls being independently rotatable with respect to each other, wherein said jacket has an inner surface which is essentially adapted to the outer surface of the rolls, rotational movement is imparted to at least one of the rolls of said device, and changes in the state of said particles are determined from which mechanical stress load acting on the particles can be determined.
