Scanning electron microscopy can be a fascinating and informative component of a wide variety of structural research projects. The Duke University Department of Biology SEM facility offers the use of an Environmental Scanning Electron Microscope (ESEM). Unlike a conventional SEM, the ESEM can be used to examine specimens which would be distorted or destroyed by standard preparation techniques.
This facility is available for faculty, post-doctoral and student research, as well as for course demonstrations.

The ESEM can be used to examine:
- Fully hydrated (not frozen) samples
- Liquid surfaces (note: submerged samples cannot be seen)
- Uncoated, non-conductive samples
- Conventionally dried and coated samples
Pathogenic samples must be killed prior to their arrival in the ESEM lab.
The ESEM lab is located in the Biological Sciences Building in room 0072. For detailed instructions, select directions.
Please feel free to contact Leslie Eibest for more information concerning instrumentation, scheduling, or specimen preparation. I can be reached in the mornings at (919) 684-2547, or at leibest@duke.edu. To reach the sign-up calendar, select ESEM sign-up (but first-time users should contact me first).
For frequently asked questions, please select FAQs.
Researchers requiring exceptionally high (2 - 100 nanometer) resolution imaging may wish to contact the Shared Materials Instrumentation Facility (http://smif.lab.duke.edu/) for information concerning the use of their field emission XL30 SEM.
We gratefully acknowledge National Science Foundation support (award # DBI-0098534) for the acquisition of the ESEM.
