It was great to see all of you and your interest in science. I enjoyed contributing to the lesson. Here is possibly the smallest Girl Scout logo every made :) The total width of the logo is ~7.5 micrometers. That's the same size of a red blood cell!! The thickness of the logo was only ~30 nanometers. Click here to download the logo in other colors. Good luck with your future science interactions and feel free to ask questions by clicking on comments below.

The image to the left is of the Girl Scouts logo captured using Atomic Force Microscopy. The troop had a hands on nano lesson explaining the fundamentals of Scanning Probe Microscopy before they saw the equipment in action at the CFN. The logo was fabricated using a top-down electron beam lithography process. The raised areas are 30nm of Cobalt on top of Silicon.
