How to do Atomic Force Microscopy in liquid conditions?
An approximately one-hour lecture on how the AFM fundamental operation modes (True Non-ContactTM, Contact, PinPoint, and Tapping) work in liquid conditions. Hardware changes for an NX system will be discussed. Application cases will be discussed as well (e.g., DNA imaging, Hydrogel analysis for protein separation, fibrils imaging). Questions are welcomed at any time during the session. Introductory Liquid imaging Video (10 min)
Interactive Demo Session Nine:
Lecture topics will be reinforced through demonstration and practice of True Non-Contact™, Tapping, and PinPoint™ in liquid conditions on a Park Systems NX series AFM. Emphasis will be put on the differences between air and liquid imaging and how this affects the acquisition of topography information. Collagen fibrils will be used as a demonstration sample. Questions are welcomed at any time during the session.
