Atomic Force Microscope and Fluorescent Microscope
This facility combines two microscopic techniques, atomic force microscopy (AFM) and fluorescent microscopy, using single-molecule imaging techniques with a total internal reflection fluorescent (TIRF) microscope. The advantage of this approach is the ability to image and localize hundreds of molecules (such as proteins) simultaneously, as well as to measure the force/stiffness of the sample.
The Bruker AFM can be used to image and measure shapes/sizes and stiffness for hard-matter samples, soft-matter samples and Biological samples. AFM can also be used in a magnetic force microscopy (MFM) mode (with a magnetic tip) to study magnetic materials, specifically thin films.
The cellTIRF® images single molecule proteins or fluorescent dyes using the TIRF mode. Individual laser lines optimize illumination depth and intensities, with this dual-view system imaging two colors simultaneously. The cellTIRF® can also perform fluorescent recovery after photobleaching (frap) imaging.
For biological samples, cell culture systems with CO2 incubators, centrifuges, water baths, fume-hood and refrigerators are available.

Helium recovery system
Quantum Design ATL-150 and a Cryomech Purifier
A closed cycle with approximately 95% efficiency (consisting of a liquefier and purifier) provides liquid helium for the Physical Quantities Measurement Systems (PPMS) and other applications requiring LHe.
The system (liquefying up to 20 LHe per day) is set up to enable a closed cycle with two PPMS instruments.
