Welcome to the East Carolina University Imaging Core Facility
Our goal is to provide comprehensive and state of the art imaging for a wide-range of biological and other disciplines on and off the East Carolina University Campus for both research and teaching.
Currently we can provide imaging in Conventional and Variable Pressure Scanning Electron Microscopy, Transmission Electron Microscopy, and Confocal Fluorescence Microscopy. Details concerning our core equipment can be found under the Core Imaging Equipment tab.
We can be found in the Howell Science Building in rooms C302-C307.
Please feel free to contact us using the information below.
Our website is new and will be evolving rapidly, please check back for new additions and changes.

Our Fees are an attempt to recoup a portion of the costs incurred in operating a microscopy facility. You can when appropriate save money by doing any specimen preparation in your laboratory, at your time, and with your supplies. The following FEES for ECU personnel are for those with grants in which microscopy fees have been budgeted for. If you do not have grant support, please contact us directly and we will try to accommodate your needs.

We follow the laboratory safety parameters of the Office of Environmental Health and Safety at East Carolina University. In general there are little or no hazards involved in using the microscopes. The chief hazards involve chemical preparation of samples for transmission electron microscopy (TEM) and conventional scanning electron microscopy (CSEM). On the main computers in C302 and C307 there is a shortcut on the desktop at the upper right corner (icon is a gold star) to a file titled Lab Safety at ECU. In that folder is the following pertinent safety information: 0_Safety at ECU (includes this document and ECU Chemical Hygiene Plan 2007), 1_Standard Operating Procedures (with focus on safety), 2_Laboratory Safety Plans, 3_Material Safety Data Sheets, and other safety information (total of 7 folders, 0-6).

Georgia Tech also has a very nice powerpoint lecture on general chemical safety. Click on the link below and then click on the “Safety Seminar Slides” near the right bottom of that page.
Computer based tutorials (Powerpoint, Word, Camtasia videos) can be a powerful way to learn, assist learning, and review many aspects of microscopy techniques. Our goal is to produce learning aids for most of the core imaging equipment and support equipment, and for using critical image analysis software. Please check back periodically to view the latest entries and updates. We also invite you to create your own learning tutorials that you might like to share with the ECU community. There will be different levels of tutorials from simple directions for experienced users to tutorials with many photographs and/or videos.
To access these tutorials click on one of the pull-down menus below for : 1. Scanning Electron Microscopy Tutorials, 2. Transmission Electron Microscopy Tutorials, 3. Confocal Microscopy Tutorials, and 4. General Imaging and Image Analysis Tutorials.
Confocal Microscopy Tutorials
We currently teach a Scanning and a Transmission Electron Microscopy course during alternate spring semesters. These courses involve considerable hands on experience on the scopes and lead to considerable proficiency in skill of microscope usage. The goal of each course is to produce a research grade poster on a subject or technique that is ultimately publishable and/or useful to research programs in the Department of Biology and elsewhere at ECU. Current course syllabi can be viewed below (SEM Syllabus followed by the TEM Syllabus). Following the syllabi are 5 examples of Student SEM posters from April 2009.

The NIH Image website is a great place to download free software for image analysis and measurement. Programs include NIH Image (for Macintosh computers), Scion Image PC (Windows), and Image J (Windows and Macintosh). There are many other programs.
The purpose of this section is to give the viewer a glimpse into the capabilities of the Imaging Core Facility. It is divided into three sections: SEM Images and Anaglyphs, TEM Images, and Confocal Images. Each segment of the gallery involves a different research project where the images are described in the context of the project or study. Studies may utilize more than one type of microscopy but will be filed under one of the three imaging microscopies mentioned above. Please also view the student posters under the Teaching Tab (Tab # 6) and the Outreach Tab (Tab # 10). The Gallery section of the website is truly in progress, please check back frequently to view new additions to the content.
SEM and Anaglyphs Gallery
Empis snoddyi males make and carry a silk nuptial gift for attracting females (Jennifer A. Sadowski et al. 1999. Behav. Ecol. Sociobiol. 45: 161-166) (video link of male swarming). This very fragile structure would be damaged by any handling and sample preparation. It was successfully imaged in Low Vacuum mode of our Quanta 200 SEM. The surface was imaged and also the entire depth of the gift wall thereby showing that the wall is made up of variable “multigons” , kind of like variable bubble wrap.
Drosophila melanogaster (Fruit Fly) egg chamber. DNA appears blue while Actin appears in green. Follicle Cells (which manufacture the chorion or egg shell) surround the developing oocyte which is nourished by the large nurse cells at the base.
We relish the idea of exposing students of all ages to the capabilities and wonders of different modes of microscopy/imaging. Since September 2009 we have had some educational programs involving 4-H students of a wide range of ages and some local high-school students. Please feel free to contact us for your imaging education desires.
These Aphids from a cotton leaf in the ECU Biology Greenhouse were collected at 10:30 AM 30 June 2009 and then imaged directly with no specimen preparation at all in the Low Vacuum mode of the Quanta 200 SEM at 1 Torr and room temperature. The Aphids were still alive 2.5 hours later!
