This exhibit demonstrates how materials at the nanoscale can have unexpected properties. The tabletop interactive, Quantum Dots, focuses on the property of color and how a material’s color may change when brought down to the nanoscale. Visitors alter the size of a magnified quantum dot and watch the light that it emits shift from red to blue as it shrinks to a fraction of a nanometer. The copy panel and side monitors explain how unexpected properties are being used in real-world applications of quantum dots and nanoparticles, from medical imaging to consumer goods.
The purpose of this activity is to show that nanosize particles of a given substance often exhibit different properties and behavior than macro or micro size particles of the same material. The property studied in this activity is the absorption and reflection of light which is based on energy levels that are determined by size and bonding arrangements of the materials.
“Making Molecular Movies with QSTORM” is a public presentation that details the on-going interdisciplinary research project of a group of scientists/engineers who are collaborating to make a breakthrough in biological imaging. They are trying to make movies of the molecular machinery at work inside living cells at a greater resolution than ever before.
