Gold Nanoparticles (HS)

Nanostructured materials are being used to reduce the weight of cars, buildings, and other infrastructure
reducing the amount of materials needed and saving energy. Unintentional nanomaterials, such as
nanoplastics, are also proving to be hazardous to the environment. In the first activity we will discuss some of the properties of light, describe how these can be used to characterize nanomaterials, and build a papercraft spectrophotometer for measuring the light emitted by different sources. In the second activity, we will discuss how nanoparticles can be formed and synthesize gold nanoparticles in the lab.
