WebNote that in biophysics, hydrodynamic radius refers to the Stokes radius, [2] or commonly to the apparent Stokes radius obtained from size exclusion chromatography. [3] The theoretical hydrodynamic radius arises in the study of the dynamic properties of polymers moving in a solvent. It is often similar in magnitude to the radius of gyration. Whether a polymer is flexible or not depends on the scale of interest. For example, the persistence length of double-stranded DNA is about 50 nm. Looking at length scale smaller than 50 nm, it behaves more or less like a rigid rod. At length scale much larger than 50 nm, it behaves like a flexible chain.
