Experiments are described that involve undergraduates learning concepts of nanoscience and chemistry. Students prepare nanopatterns of organosilane films using protocols of particle lithography. A few basic techniques are needed to prepare samples, such as centrifuging, mixing, heating, and drying. Students obtain hands-on skills with nanoscale imaging using an atomic force microscope (AFM) when they learn to characterize samples. Designed surfaces are made using a surface mask of latex or silica spheres to generate nanopatterns of organosilanes. An organic thin film is applied to the substrate using steps of either heated vapor deposition or immersion in solution. The steps for preparing samples are not complicated; however, the nanostructures that are produced by particle lithography are exquisitely regular in geometry and surface arrangement. At the molecular level, two types of sample morphology can be made depending on the step for depositing organosilanes. Ring-shaped nanostructures are produced wit...
