This is an interesting workflow where very small where magnetic beads are used to pull the target protein complex. Then the beads are pulled onto a cryoEM grid using a magnet on the back of a gold grid with graphene layer. After that, plunged using trad equipment. (h/t @klausenhauser.bsky.social ).
