Encapsulation & Controlled Release

Module Abstract

This module introduces the process of forming macrocapsules and the concept of self-assembly. Forming capsules at the macro, micro, and nano levels have very important applications in drug delivery, cosmetics, food technology, and cleaning up environmental toxins. The module includes a laboratory activity that uses organic compounds, nanoparticles, and dye to allow students to study the process of encapsulation and controlled release.
