This cart demo is about Biobarcodes, a nanomedical technology that allows for massively parallel testing for disease diagnosis. Visitors learn about antibodies, how each antibody binds to a unique protein, and how biobarcoding uses nanoparticles, antibodies, DNA and magnetism to detect diseases earlier than we could detect before. Visitors assemble a jigsaw puzzle that models how Biobarcodes™ work.
This is a cart demo about how nanoparticles behave differently, in part because they have a high surface area:volume ratio. Visitors learn that smaller particles have a much higher proportion of their atoms on the surface. Visitors unfold paper cubes, drop alka-seltzer in water, turn potatoes black with iodine, and see fireballs to understand how surface area changes as you get small.
This cart demonstration introduces the nanomaterial aerogel, a glass nanofoam. Visitors learn how aerogel is made, how well it insulates, and learn about its other unique properties. They see real aerogel and feel how well it insulates.
This cart demo is about piezoelectricity - how some crystals produce electricity when you squeeze them. Visitors learn about the history of piezoelectricity, how it's used, and how it's applied in nanotechnology. They make electric sparks, handle models and listen to cheesy music.
Presenter puts Mentos candy into soda to create a soda fountain. This is a dramatic demonstration of the effects of surface area. This demonstration isn’t heavily focused on nanotechnology,but can be a spectacular finale that you add on to other nano demos like Intro to Nano or Surface Area. (It’s probably best as a substitution for Alka-Seltzer, rather than being performed with it.) It’s also just a crowd pleasing demo that briefly mentions nano.
"Snowflakes" is a public presentation that introduces nanoscale science through the subject of snowflakes. Visitors learn that the complex structure of snowflakes results from the nanoscale arrangement of water molecules in an ice crystal, and that snowflakes are examples of self-assembled systems studied by nanoscientists. During the program, visitors watch videos of snowflakes growing and observe real ice crystals growing in a chilled chamber.
