      abstract     = {The rotational diffusive motion of a self-propelled,
                      attractive spherical colloid immersed in a solution of
                      self-avoiding polymers is studied by mesoscale hydrodynamic
                      simulations. A drastic enhancement of the rotational
                      diffusion by more than an order of magnitude in the presence
                      of activity is obtained. The amplification is a consequence
                      of two effects, a decrease of the amount of adsorbed
                      polymers by active motion and an asymmetric encounter with
                      polymers on the squirmer surface, which yields an additional
                      torque and random noise for the rotational motion. Our
                      simulations suggest a way to control the rotational dynamics
                      of squirmer-type microswimmers by the degree of polymer
                      adsorption and system heterogeneity.},
