Breathable Lignin Nanoparticles as Reversible Gas Swellable Nanoreactors.

The design of stimuli-responsive lignin nanoparticles (LNPs) for advanced applications has hitherto been limited to the preparation of lignin-grafted polymers in which usually the lignin content is low (<25 wt.%) and its role is debatable. Here, the preparation of O -responsive LNPs exceeding 75 wt.
