Surface Area - stage presentation

This is a large group version of the Surface Area program. In this interactive stage presentation, audience members are measured in nanometers and demonstrate the effectiveness of "nano" silver in killing germs. Other highlights include a fireball that starts and ends the show. Visitors learn that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

High School Nanoscience Program - Biotoxicity

"Biotoxicity" is an experiment that explores the antimicrobial properties and biotoxicity of nanoscale particles of silver. Students first produce nanosilver and then use the rate of respiration of yeast in the presence of different forms of silver to compare their biotoxicity.
