Multilayer Encapsulation of Biological Media for Controlled Release Coatings

This classroom module will help students understand "how a polymer based multilayered coating method can be used to control the release of biological agents for different applications." The experiment is described step by step in the document; photographs are also included. The activity is intended for high school students in advanced biology classes, but may also work for college classes. The experiment should take about 40 minutes to complete. This document will serve as a framework for instructors and may be downloaded in PDF format.
