Title: Methods and apparatus for preparing aqueous specimens for electron microscopy using volatile surfactants

Abstract

This disclosure provides systems, methods, and apparatus related to the preparation of electron microscopy specimens. In one aspect, a method includes providing an electron microscopy grid. An aqueous suspension including an electron microscopy sample is deposited on the electron microscopy grid. A portion of the aqueous suspension is removed from the electron microscopy grid. A volatile surfactant is contacted to the aqueous suspension. A thickness of aqueous suspension is allowed to decrease over a period of time. The aqueous suspension is then frozen.
