Educational activities for physical pharmacy classes on colloids

Abstract

Colloids are an important component of physical chemistry and physical pharmacy curricula. In pharmacy, colloidal systems and concepts are encountered in dosage forms (e.g., suspensions, emulsions) and many drug delivery systems (e.g., nanoparticles). Since colloids may appear rather theoretical in nature and may be difficult to grasp when taught to students for the first time, practical activities are invaluable in teaching this topic. This paper presents some useful activities for classes on colloids that may be incorporated in physical pharmacy and physical chemistry courses.
