Researchers from the New Castle University highlight in their review article recent progress in the development of polymeric nanoparticles. According to the authors of the study, Alexander W. Jackson and David A. Fulton, new polymeric nanoparticles can display stimuli-responsiveness on account of their incorporation of dynamic covalent bonds (DCBs).

These bonds can form and cleave in response to changes in environmental parameters, such as pH or presence of reducing/oxidizing agents. Chemists have utilized this reversibility to make increasingly sophisticated stimuli-responsive polymeric nanoparticles. Due to DCBs polymeric nanoparticles can also modify their constitutions by reshuffling, incorporating or releasing components.

These stimuli-responsive polymeric nanoparticles could find application in fields such as paints, coatings and adhesives. The complete study will appear in the Polymer Chemistry, vol. 4, issue 1, 2013, pp. 31-45.
