In order to quantify the surface morphology of thin polymer films, which are typically 0.02 {mu}m to 5.0 {mu}m thick, we employ a number of complementary techniques, including scanning probe microscopy (SPM), scanning electron microscopy (SEM), light optical microscopy (LOM), and transmission electron microscopy (TEM). Among these techniques, SPM provides convenient information about the morphology of these polymer films at the biologically-relevant length scales of 1 {mu}m to 100{mu}m. SPM can be used to determine characteristic length scales and identify related scaling regimes. The instrument used for this work was a Digital Instruments NanoScope III with Multimode Head.
