Presentation at Lehigh University, Bethlehem, Penn, ACS Surface and Colloids Symposium, Tuesday, 21 June 2000.
I’m Eric Aston from the Department of Chemical Engineering at the University of Washington where I work with Professor John Berg.
Atomic force microscopy is probably the most versatile method for measuring colloid interactions quantitatively and directly with a single particle.
The AFM has become a commonplace instrument to perform a number of routine functions like mapping topography and some other near surface properties on colloidal scales.
While many new modes of AFM are being pioneered from year to year, only recently has it been used to measure interactions at fluid-fluid interfaces.
We have found it extremely useful, specifically, for exploring agglomeration processes of oil and various particles in aqueous media…
