An octopus-like polymer can 'walk' along the wall of a narrow channel as it is pushed through by a solvent. Now research in The Journal of Chemical Physics, which is published by the American Institute of Physics, provides a theoretical model that compares the transport characteristics of straight- and branched-chain polymers in smooth channels as well as in channels whose walls interact with the polymer - work that could aid in the development of carrier molecules for delivering drugs at a controlled rate in the body...
