UTSA Kleberg Advanced Microscopy Center

Overview of Services

UTSA houses the most important state-of-the-art instruments in electron microscopy and other advanced microscopy equipment. The Center propels the world-class research in nanotechnology, biology, chemistry and condensed matter. This facility includes an aberration-corrected microscope on the STEM mode JEOL ARM 200F with a spatial resolution of 78 picometers.


High resolution electron microscopes such as a field emission gun JEOL 2010F and a STEM Hitachi S5500 as well as confocal and probe microscopes. The Center is focused in high-resolution imaging, electron diffraction, electron holography, electron tomography, cryo-TEM and EELS. In addition, the group works with in situ electron microscopy: nanomechanical, electrical and optical measurements.


The Kleberg Advanced Microscopy Center is a part of the Research Centers in Minority Institutions (RCMI) Program within the “Nanotechnology and Human Health Core”.  Additional information about this program available on-line.

Training Policies

1) All users must undergo training on the use of instrumentation prior to having access to the facility. The amount of training will vary depending upon user experience. All training is done by appointment and requests should be sent to the Director via email. 


2) The core also offers personal in-depth training in methods of image processing and analysis using data acquired by the user. While this level of training is not required in order to obtain independent access to instrumentation, it is highly recommended. All training is done by appointment and requests should be sent to the Director via email.


3) Upon the completion of training, an internal user will be granted access to the main entrance door and to each room housing the instrumentation for which the user is trained to use independently.


4) Under no circumstances should an authorized user lend their banner ID to another individual or swipe their banner ID in order to grant an unauthorized user access to the imaging center. Any unauthorized access to instrumentation will result in the suspension of all user privileges.


5) All work areas should be left clean, regardless if another user is to come on the system following your reserved time slot.


6) Data is NOT indefinitely stored on the local acquisition computer. It is uploaded regularly to our dedicated server, and removed from microscope computer. Data management is a component of user training.
