Active microrheological techniques employ external forces, including magnetic and optical tweezers, to manipulate the probes. These methods are capable of assessing nonequilibrium systems and nonlinear behaviors. On the other hand, passive microrheological techniques, such as dynamic light scattering (DLS), diffusing wave spectroscopy (DWS), and passive particle tracking microrheology (PTM), rely on thermal energy to drive the tracers. However, this energy is insufficient to generate discernible displacement when particles are embedded in rigid materials. As a result, passive microrheology is best suited for homogeneous and pliable media
