  • FABRICATING THIN FILM LIQUID CELLS
    Publication number: 20230025535
    Abstract: A thin film liquid cell suitable for transmission electron microscopy at room temperature is fabricated as follows. A thin film floating on a liquid is prepared. A droplet of the liquid with the thin film floating thereon is transferred to a support by means of a loop. The loop carries the droplet and the droplet carries the thin film during this transfer. Sufficient liquid from the droplet on the support is removed to form the thin film liquid cell.
