Self-Assembly and Nanotechnology: Real-Time, Hands-On, and Safe Experiments for K-12 Students
Bagaria, Hitesh G.; Dean, Michelle R.; Nichol, Carolyn A.; Wong, Michael S.
Journal of Chemical Education, v88 n5 p609-614 May 2011
What students and teachers often ask is, how are nano-sized materials made when they are so small? One answer is through the process of self-assembly in which molecules, polymers, and nanoparticles connect to form larger objects of a defined structure and shape. Two hands-on experiments are presented in which students prepare capsules in real time using simple and safe ingredients and study the materials for encapsulation and release of food coloring dye. These experiments are visual and interactive demonstrations of self-assembly (as a synthesis tool) and nanotechnology (in which nanomaterial can be made to perform useful functions), and build on the concepts of acid-base chemistry and electrostatic interaction. (Contains 4 figures, 2 schemes, and 1 note.)
