Transient dynamics of a colloidal particle driven through a viscoelastic fluid

Transient dynamics of a colloidal particle driven through a viscoelastic fluid

We study the transient motion of a colloidal particle actively dragged by an optical trap through different viscoelastic fluids (wormlike micelles, polymer solutions, and entangled λ -phage DNA). We observe that, after sudden removal of the moving trap, the particle recoils due to the recovery of th...
