A statistical mechanics model is proposed for the storage and dissipative modulus of diffusion microrheology valid at the regime of linear flow without external magnetic or electric perturbations. A comparison of these moduli with similar viscoelastic properties obtained from Langevin dynamics simulations yields qualitative agreement at low-frequency responses.
