In Observance of U.S. Holiday, Martin Luther King Jr. Day, Agilent Cross Lab/ iLab Operations Software will be closed during U.S. hours on Monday January 21st, 2019. We will resume regular U.S. support hours on Tuesday January 22nd, 2018. EU and APAC Support will remain open during this time. For urgent matters, please add "Urgent" to the ticket/ email subject or press "1", when prompted, to escalate a call on the iLab Support phone and we will prioritize those requests first. Issues from the Kiosk and Interlock issues on January 18th, 2019 should be resolved now. If any issues persist, we recommend first performing a power to cycle the bridge.

UTHealth Atomic Force Microscopy

Overview of Services

Atomic Force Microscopy (AFM) is a noninvasive technique that reproduces topographic images under physiological-like conditions. Scanning can be performed in air or in a liquid environment. A range of samples, from living cells down to single molecules, can be imaged. AFM is also an attractive tool for studying the dynamics of cellular endocytosis of nanovectors and the systemic response to biological processes.  An area of major interest is to determine the stiffness of a sample (Elastic Modulus). The elasticity of the cell membrane can vary between cell types as a function of growth, differentiation, disease or treatment. In addition, non-cellular structures can also be imaged.  
The Core uses a BioScope™ II atomic force microscope (Bruker Corporation; Santa Barbara, CA) that requires minimal sample preparation.  The BioScope™ II is integrated with a Nikon TE2000 inverted optical microscope to simultaneously acquire bright-field and fluorescence images of samples under study.
