Query: Colloidal suspensions of C-particles: Entanglement, percolation and
  microrheology   We explore structural and dynamical behavior of concentrated colloidal
suspensions made up by C-shape particles using Brownian dynamics computer
simulations and theory. In particular, we focus on the entanglement process
between nearby particles for almost closed C-shapes with a small opening angle.
Depending on the opening angle and the particle concentration, there is a
percolation transition for the cluster of entangled particles which shows the
classical scaling characteristics. In a broad density range below the
percolation threshold, we find a stretched exponential function for the
dynamical decorrelation of the entanglement process. Finally, we study a set-up
typical in microrheology by dragging a single tagged particle with constant
speed through the suspension. We measure the cluster connected to and dragged
with this tagged particle. In agreement with a phenomenological theory, the
size of the dragged cluster depends on the dragging direction and increases
markedly with the dragging speed.
