Yeah lots of single molecule studies (strength of an actin filament, how much force needed to 'unfold' various proteins, etc). And this was 20 years ago when I was in grad school. Haven't kept up with the state of the art today.
interesting. all the people doing that in my day (also 20 years ago) used fluorescent microscopes (Ron Vale) with labelled protein. I can't see how you could unfold a protein using AFM, since it's in vacuum state, although I totally understand how optical tweezers would be fine to do this in solution.
