TRINITY ELECTRON MICROSCOPY FACILITIES
are among the most important scientific instruments to be developed in the last
50 years. They serve vital roles
in scientific research and medicine, and an ability to use them and interpret
the information they provide an be immensely valuable for students, physicians,
and research scientists.
Trinity College has constructed two excellent Transmission Electron
Microscopy laboratories, which are available for use by students and faculty
for the purposes of education and scientific research. The first of these laboratories is
located in the Life Sciences Center, and houses a Zeiss
transmission electron microscope (EM 900) with CCD camera, a lab for
preparing tissues and materials samples, an ultramicrotomy lab, and a dedicated
darkroom. The second facility has been constructed in the McCook building, and
houses a sophisticated Philips
CM12 with STEM capabilities. Constructed
at college expense, the TEM laboratories were equipped with the generous
assistance of funds from the National Science Foundation and the DeCamp
Foundation. In addition to the two
transmission EMs, Trinity has two scanning electron microscopes: a JEOL
JSM series SEM located in the McCook Building, and a Cambridge CamScan
series 4 SEM with X-ray detector, located in Clement Hall. In addition to these instruments,
Trinity has an Atomic Force Microscope
(AFM) located in the MCEC Building, and a Scanning Tunneling Microscope (STM) which
is housed in McCook. Excellent histology,
cryotomy, and computer- interfaced photomicroscopy facilities are also to be
found in the Life Sciences Center as well as in Clement.
The EM laboratory facilities are shared
by six departments/ programs: Biology,
Chemistry, and Physics.
Among the several
courses for which they are used is Biological Electron
Microscopy (Bio 350), which is taught by Dr. Daniel Blackburn and Ms. Ann Lehman. The labs are also used in a variety of
other courses throughout the natural sciences. The EM instruments and laboratories
also are available for faculty research and faculty -sponsored undergraduate
research and research training. These facilities enhance the excellent
opportunities for Trinity undergraduates to conduct cutting-edge original
research with highly sophisticated instrumentation. Examples of transmission
electron micrographs taken by Trinity students are shown here.
The TEM laboratories are overseen by Ms.
(the Assistant Director of the EM Facility) and Professor Daniel Blackburn
(Director of the EM Facility). Students and faculty interested in using the
facilities or learning to use the instruments should contact Ms. Lehman or Dr.
