The loop formation(LF) of a single polymer chain has been a topic of academic interest because LF should be an important model system for protein folding and DNA hairpin formation. Many experiments and theories have been, therefore, performed. The celebrated Kramers theory(KT) predicted that the rate constant(krxn) of the LF should be inversely proportional to the viscosity(ηsol), i.e krxn~ηsol-1.However, recent studies showed that the theory worked properly only when the viscosity of the medium was sufficiently large. The KT failed and the fractional viscosity dependence of krxn, i.e. krxn~ηsol-α(α |
