Bead milling or bead homogenization is a mechanical cell disruption process with some degree of complexity. Through this technique, cell disruption is induced through shear forces produced during the rotary movement of the cells and the beads and cell grinding between beads [12] (Figure1). Beadcell collisions are also purportedly implicated
