Optical images of dissolution of capsules with compositions highlighted in the figure showing (A-C) instantaneous, (D-E) sustained, pulsed and diffuse release. (F) High magnification images of the surface cracks of the capsule and (G) the emanating micron-sized nanoparticle clusters. (H) The droplet radius of the composite (D) capsule was found to remain approximately constant over time, and release of micron-sized nanoparticle clusters occurs in bursts, over long timescales, tuneable with pH.

Nanocomposite Capsules with Directional, Pulsed Nanoparticle Release

The precise spatio-temporal delivery of nanoparticles from polymeric capsules is required for applications ranging from medicine to materials science. Researchers from the Imperial College London, UK, have demonstrated that microporosity and capsule morphology... (Read more)
