wow – we could use it to track polymers in our experiments, hopefully

We did few experiments with dilute polymers, see the list of publications [here]. Most noticeable is the Physics of Fluds, 2005. However, these experiments have two-three major drawbacks:

  1. we do not know where the polymers in the flow
  2. we do not know precisely the amount of energy that is applied to the flow
  3. we do not know if polymers were stretched or not and if yes, how much

Now, the recent developments bring some hope to resolve at least two of the three problems – to see the polymers and maybe to know how much stress they feel.

The latest polymers are chameleon-like: they change colour on deformation. The transduction mechanism underpinning this effect could be used to make polymers that respond in many other ways to mechanical stress.
