Abstract
A device and method for lysing biological species present in a fluid includes implementing a rough surface against which the objects to be lysed are crushed by a shearing motion. A device for mechanically lysing biological species has a first and second wall mounted movable relative to each other, between an initial position in which the walls are separated from each other, and a lysing position in which the first wall presses against the second wall. The first and second walls also are mounted shearingly movable relative to each other in the lysing position. At least one of the first or second walls has a rough bearing surface against the other wall and has a mean surface roughness parameter Ra of between 0.2 μm and 10 μm, and preferably between 0.2 μm and 3 μm.
