The contact mode AFM could be used to "sweep" the slipcover and expose the mark. As an example, in situ observation of the bovine serum albumin adsorption film on highly ordered pyrolytic graphite was described. When the marks, atomic steps on HOPG, were covered by BSA molecules, contact mode AFM could "sweep" the BSA molecules away.
