Researchers have made nanosized polymer capsules with built-in channels that release the particles’ payload when triggered by a high pH (Macromolecules 2014, DOI: 10.1021/ma501099f). The nanocapsules could be useful for the controlled delivery of drug molecules and proteins of specific sizes inside the body.

Polymer capsules have become a popular tool in the pharmaceutical and personal care industries to deliver drugs, hormones, and fragrances under certain conditions. . . .
