We describe the design, construction, and operation of a LEGO TM model of a dynamic force microscope, using magnetic forces as an analog of interatomic interactions. The macroscope provides key insights into the operating principles of frequency modulated non-contact atomic force microscopy-currently the scanning probe technique of choice for maximal (i.e., submolecular) spatial resolution-and is, therefore, particularly suited as a project or demonstration for nanoscience education at the undergraduate or postgraduate level.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
