Formation and Use of Globular Protein Aggregates

Globular protein aggregates are used to texture aqueous systems either as gelling agents, viscosifiers or stabilizers of emulsions, e.g. in the food and cosmetics industries. Globular proteins are characterized by a rather rigid... (Read more)

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.
