摘要：

With optical tweezers plus fluorescent labels it is now possible to force, and to observe, the stretching and the relaxation of a single polymer chain. We calculate here the unwinding of a tethered, flexible, chain (N monomers) immersed in a solvent if, at time t = 0 starting from rest, one imposes either a flow (V) of the solvent, or an external force f on the free end.
