Atomic Force Microscopy of individual water molecules at room temperature

Heterodyne laser doppler interferometry has enabled atomic force microscopy in the megahertz regime with 10 pm order vibrations in liquid and vacuum. Especially in liquid, incorporation of photothermal exictation has enabled imaging of individual water molecules ordered on the surface of mica at room temperature. The talk will address the novel instrumentation and the model of what we are seeing in water.
