  1. Mixtures and Nanotechnology

    11 Jan 2017 | | Contributor(s):: Joyce Palmer Allen

    The purpose of this unit is to help students make the connection that the classification of mixtures is based on the size of particles. This connects to two of the Big Ideas in Nanoscale Science and Engineering (Stevens, Sutherland, and Krajick 2009). The first is Size and Scale or factors...

  2. Nanotechnology Invention and Design: Phase Changes, Energy, and Crystals

    11 Jan 2017 | | Contributor(s):: Daniella Duran

    This 3-part lesson introduces the nanoscale effect of various energy inputs on the crystal lattice of a smart material, Nitinol, and then invites students to become nanotechnology inventors. Students will first explore how energy exchanges lead to solid-state phase changes at the macroscale and...

  3. Synthesis and Characterization of CdSe Qunatum Dots

    11 Jan 2017 | | Contributor(s):: Nicholas Blake

    In this laboratory, students will study how surfactant-based chemistry can be used to synthesize CdSe quantum dots and study how the size of the quantum dots can be controlled by varying reaction time. The laboratory will  demonstrate how the color of these quantum dots can be connected to...

  4. Wet Etching in Nanofabrication

    11 Jan 2017 | | Contributor(s):: Manuel Casillas

    This lab will help students understand how chemical reactions are used to create the specific shapes on surfaces of crystalline materials, which make up functional components within electronics. The fabrication of electronic devices is now reaching into the nanoscale with the capability of more...

  5. Silver Nanoparticle Synthesis, Spectroscopy, and Bacterial Growth

    11 Jan 2017 | | Contributor(s):: Pennsylvania State University

    Students will learn about the differences in physical propoerties at the nanoscale as compared to the same materials at the macroscale. The students will demonstrate the appropriate use of a spectrophotometer and will convert between different units of measurement. This unit assists students in...

  6. Silver Nanoparticle Socks

    10 Jan 2017 | | Contributor(s):: Pennsylvania State Univeristy

    This lab will allow students to use the pure silver nanoparticles they synthesize to create antibacterial socks. They will compare their socks with socks that have been treated with a commercial silver spray, socks that have been treated in a factory, and a control that was not been...

  7. Coffee Break with Nanoscience: Film Formation and "Coffee Rings"

    28 Oct 2016 | | Contributor(s):: Irina Golub, James Marti

    This lab explores issues that engineers and scientists face in working with thin film i.e., dealing with two phenomena that work against them: cracking and the coffee ring effect. This lab will explore the phenomena involved in making thin film coatings. Students will explore the problems that...

  8. The Blood Glucose Monitor

    28 Oct 2016 | | Contributor(s):: Steven Thedford, Samantha Andrews, Nancy Healy

    Students are introduced to glucose monitors, how these biosensors are being improved with naotechnology, and they test glucose levels. The purpose of the lab is to measure the glucose concentration of several synthetic blood and urine samples to determine which patients have diabetes. Students...

  9. Using Gold Nanoparticles for Bacterial Detection

    28 Oct 2016 | | Contributor(s):: Michael L. Falk

    This lab is designed to introduce students to gold nanoparticles and some of their applications. Students will create gold nanoparticles (GNPs) and learn the potential disease detection uses of GNPs, conduct research on modifying GNPs to be specific to other molecules, and complete a simulation...
