Forces used in AFM

  1. May 15, 2009 #1
    I am trying to make sense of some notes given to me by my lecturer; he is not responding and exam is soon! The question is 1) name 3 types of interaction measured in AFM 2) name 3 types of interaction forces that are measured in AFM 3) how are the forces measured?

    The notes say:

    Interaction type (some stats relevant to each one)
    Ion/Ion
    Ion/Dipole
    Ion/Dipole

    Chemical bonds
    Covalent/Ionic
    Hydrogen
    Van de Waals

    Typical forces
    Covalent bonds
    Hydrogen bonds
    Van de Waals
    Layer forces
    Miniskus forces

    So the various interactions are ion/ion ion/dipole dipole/dipole?
    The forces are any of those labelled under typical forces?
    How does the AFM tip interact with the surface?

    Sorry massive list of questions.
