title: pH-mediated catch and release of charged molecules with porous hollow nanocapsules.
abstract: Here, we show that the charge of the nanopores in the nanometer-thin shells of hollow porous nanocapsules can regulate the transport of charged molecules. By changing the pH of external aqueous solution, we can entrap charged molecules in nanocapsules and trigger the release of encapsulated content.
