Self- Assembly and Nanotechnology: Real-Time, Hands- On, and Safe Experiments for K-12 Students

One question that students and teachers often ask is how are nano-sized things made when they are so small? One answer is through the process of self assembly, in which molecules, polymers, and nanoparticles can connect to form larger objects of a defined structure and shape. Two hands-on experiment procedures are presented, in which students can prepare capsules in real time using simple and safe ingredients, and can study them for encapsulation and release of food coloring dye. These experiments provide a visual and interactive manner for the concepts of self-assembly (as a synthesis tool) and nanotechnology (in which nanomaterial can be made to perform useful functions) to be learned.
