Abstract: Imaging by cryo-electron microscopy (cryo-EM) requires that a sample be encased in an amorphous solid, such as amorphous ice. In current cryo-EM preparation systems, once the sample has been deposited on an EM grid and coated in the amorphous solid, the EM grid must be removed from vacuum and then transferred into the vacuum of the cryo-EM system. As a result, samples deposited on the grid are exposed to damage and contamination. The present invention provides improved EM grid handling systems and devices compatible with advanced cryo-EM sample preparation techniques and which reduce or eliminate exposure of the sample on the grid to atmosphere and elevated temperatures. These methods and devices will also significantly reduce handling time and complexities associated with cryo-EM sample preparation.

Abstract: In the system and method disclosed, an ultrahigh vacuum (UHV) scanning tunneling microscope (STM) tip is used to selectively desorb hydrogen atoms from the Si(100)-2X1:H surface by injecting electrons at a negative sample bias voltage.
