Nanotechnology is the study of the preparation and properties of atomic, molecular, or macromolecular particles in the size range of 1–100 nanometers. An exciting new breakthrough in nanotechnology involves the delivery and transport of medicines to treatment areas in the body by encapsulating drugs in molecular “cages” consisting of nanoparticles. In this modern, hands-on lab activity, students will model this technology on a larger scale using sodium alginate, a natural polymer from seaweed. When sodium alginate is added to a solution containing calcium ions, calcium alginate precipitates out as microspheres. These “capsules” can be used to trap and also release indicator dye molecules. A engaging modern-chemistry experiment! Complete for 30 students working in pairs. Reusable 6-well reaction plates are recommended and available separately.
