Our first day of classes began with an introduction to microscopy. We discussed the various types of microscopes ranging from a scanning electron microscope (SEM) to transmitting electron microscopes (TES). 
As part of this opening, we toured the basement levels of the California NanoSystems Institute building. We divided into three groups so as we could tour the three labs.
The first lab we touredmade use of the SEM microscope with the assistance of fluorescents. These colors are generated from a variety of ways including GFP and quantum dots. This is essential to visualize the incredibly small areas of the specimen. This lab was connected to the second lab toured, so we essentially just expounded from this topic.
The 
second lab in our rotating lab visits allowed us to actually see the application of the specimens’ illumination by using colors. We were shown a sample that had different areas implanted by using colors. The sample used three colors (blue, green, and red) to display the use of the application of the work in the first lab.
The final lab we toured displayed another form of microscopy. This microscope was used by placing the sample within the large chamber which was coated with the foil to mantain temperature in the chamber. The lab included a 
large amount of devices as well that enhanced the modern high-end microscope.
This rotating lab tour was a great way to begin the session. It taught us the basics of modern microscopy as well as gave us an idea of the high-tech science that is currently being explored. I believe this was pivotal in starting the session so as to let us encounter the concepts and the facility we would be spending out time with.
