Active multi-point microrheology of cytoskeletal networks
  Active microrheology is a valuable tool to determine viscoelastic properties of polymer networks. Observing the beads response to the excitation of a reference leads to dynamic and morphological information of the material. In this work we present an expansion of the well-known active two-point microrheology. By measuring the response of multiple particles in the viscoelastic medium in response to the excitation of a reference particle we are able to determine the force propagation in the polymer network.
