Hydrodynamics and DNA (no turbulence though)

In Ghosal’s explanation, the DNA pulls some of the fluid
surrounding the molecule through the channel with it. The lubrication
forces arising in this fluid layer create the resistance that opposes
the electrical pulling force. Ghosal’s calculations in the PRL
paper show that his theoretical model is consistent with experimental
results and explains the DNA’s speed.

What’s Next In Science & Technology – Theory based on classical hydrodynamics could reduce costs of DNA sequencing

I wonder what we can do with dilute polymer molecules? we know they take water molecules with it, so what? can we make a swirling nano-probe, to measure their ability to swirl?
