BIOLOGY 210 - Scanning Electron Microscopy

[Go to semester: Fall 2002, Fall 2003, Spring 2005, Spring 2006]

The scanning electron microscope (SEM) is used to teach principles of electron optics and digital imaging for the study of surface morphology and microstructure of materials. The following micrographs were captured by students in BIOL 210.
