Abstract:
A device for the lysis of at least one species of micro-organism, so as to release at least one intracellular biological component, which comprises:a container defining at least one enclosure for containing a biological sample in liquid medium comprising said species of micro-organism; at least one large-sized magnetic particle, made of at least one material which is relatively hard and substantially inert with respect to said species of micro-organism, and which has a magnetic susceptibility, contained in said enclosure; a multiplicity of small-sized particles, each made of at least one material which is relatively hard and substantially inert with respect to said species of micro-organism, contained in said enclosure; and a means external to said container and capable of generating a variable magnetic field passing through said container and enclosure, such that said variable magnetic field directly moves said magnetic particle inside said enclosure, causing said small-sized particles to move in grinding motion with respect to said species of micro-organism.
