This lab, presented by the National Nanotechnology Infrastructure Network, teaches students about gold nanoparticles (GNPs). Students will "learn the potential disease detection uses of GNPs, conduct research on modifying GNPs to be specific to other molecules, and complete a simulation using GNP assay tests to detect a simulated meningitis outbreak." A Teacher's Preparatory Guide and Student Worksheet are provided that give detailed guidance for completing the lab.
