Demonstrating Encapsulation and Release: A New Take on Alginate Complexation and the Nylon Rope TrickAndrienne C. Friedli and Inge R. Schlager Three variations on a classroom demonstration of the encapsulation of droplets and evidence for release of the interior solution are described. The first two demonstrations mimic biocompatible applications of encapsulation. A third encapsulation exercise exploits the irreversible interfacial polymerization of diamine and diacid chloride to form membranes and illustrates the detection of diamine release from the capsule using an indicator. Friedli, Andrienne C.; Schlager, Inge R. J. Chem. Educ.2005, 82, 1017.
