- COVID-19 Update: Current Status - Last Updated July 21, 2020
We are currently in Phase 3 of our ramp up plan, which means that core research facilities may begin allowing non-ASRC users on a limited basis, with up to 50% building occupancy allowed. Please review our plan for increasing on-site research activity following NYS PAUSE and check back regularly for status updates.
More information about COVID-19 related policies and phased reopening plans can be found on our User Resources page.
The ASRC Imaging Suite at GC of CUNY currently houses state-of-art 300 kV cryo-TEM, 200kV Cs corrected S/TEM, 120kV TEM, Dual-beam SEM/FIB, Raman Microscope, and super-resolution STED microscope for advanced imaging of materials and biological samples. The facility follows a user-fee based model and is open to all users, both internal and external. The facility welcomes users from academia and industry, with individual rate structures for both.
The supported applications include data collection for single particle 3D reconstruction, S/TEM and SEM imaging, advanced FIB applications (e.g. patterning, site-specific cross-sectional imaging, 2D image stack, TEM lamella preparation), chemical analysis by Energy-dispersive X-ray Spectroscopy (EDS). The facility also has plunge freezers for cryo-EM specimen preparation, plasma cleaner for SEM samples and TEM grids cleaning, and coater for coating of carbon (thermal-evaporation), Gold and Platinum (sputter coating).
We encourage researchers to get trained to become a user of the facility. Click here to find instructions and the forms necessary to become a user. A full list of instrument user rates and training information can be found here.
