We use the atomic force microscope in several different research projects (protein adsorption, polyelectrolyte adsorption, and biological membrane formation) but are also interested using this powerful tool to address other problems. The basic parameters of the instrument allow us to look at larger molecules on the surface of solid substrates. This includes both adsorbed molecules as well as surface molecules present from the termination of the bulk material. The instrument has minimum and maximum scan sizes of 400 nm² and 60 µm² respectively. This allows for resoution down to tens of nanometers which is sufficient for viewing macromolecules. If you are interested in learning about AFM or have an Idea for a project that would use the AFM please contact me!
