Evidence for the universal scaling behaviour of a freely relaxing DNA molecule. Europhysics Letters 36, no. 6: 413-418.0295-50750302-072Xhttp://nrs.harvard.edu/urn-3:HUL.InstRepos:3645425Relaxation measurements on a fluorescently labelled free DNA molecule after stretching by a Poiseuille flow in a capillary vessel reveal universal scaling features: at intermediate times the scaling exponent of the decay law for the molecule length as a function of time is found to be 0.51 +/- 0.05. This law is in agreement with the prediction of the Brochard-Wyart "stem and flower" model for the relaxation of a stretched polymer chain.en-US2010-02-1810.1209/epl/i1996-00244-6
