Results from the CFM reveal reduced interaction between the probe and areas with grafted-PAM on the surface. The topography and the friction trace-minus-retrace (TMR) images are complementary to one another resulting from the reduced interaction of the probe that has specificity to chemical domains. © 2008 World Scientific Publishing Company.Mahidol UniversityChemical EngineeringChemistryMaterials ScienceArticleSCOPUS10.1142/S0256767908002923
