WebIn latter case, we have introduced an attractive interaction via Asakura-Oosawa potential using free linear polymer added to this system. We characterize the mechanical properties applying dynamic light scattering based optical microrheology at the microscopic level, and mechanical bulk rheology at the macroscopic level.
