Too Small to See invites you to explore the world of nanotechnology, which involves the super tiny – things smaller than a cell in your body, thinner than a hair on your head. Nanotechnology is used to make computer chips, new medicines and to treat cancer. The exhibit includes Nano Stories, featuring researchers that use nanotechnology to develop applications that are important in everyday life, such as targeting tumors and killing them with infrared irradiation. Build a Molecule allows you to use models to build molecules that you come in contact with every day, such as aspirin. In Particle Progression, use your senses to go on a nano journey from small (sand) to smaller (dust) to nano (smell).
