Carbon Holey Film for Cryo-TEM


This carbon holey film was made from a silicon wafer template I fabricated.

I made the wafer template and the imaged sample is carbon film Dr. Kenneth Downing made using the template.

Credit to the UCB Nanolab, for tools and guidance. This was my first experience with wafer fabrication, but definitely not the last. This technique is not fully perfected yet – I’m working on a better way to make long lasting carbon film templates for cryomicroscopy.
