Active polymers in porous media:
We have been working on the dynamics of active linear and ring polymers in two dimensional porous media. Our works illustrate the interplay of activity, confinement, topology and mechanical properties of the chains. More recently we have explored the problem with different types of active chains and the results are strongly model dependent.
