Homework Help: 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)

    Chemical bonds
    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.
