Ok, the experiment is about AFM imaging ds DNA which are 14bp long. It's to compare between using a normal AFM tip (larger tip) and a carbon nanotube tip (smaller tip) to look at the same dsDNA molecule. Using the larger tip shows that the height is 0.5nm less than the height seen with the...
I see, so how does that explain my experiment results? Since you said that there would be a smaller deformation on a larger surface with the tip that is larger and a larger deformation on a smaller surface with the smaller tip, why do I get a larger height change with the larger tip? The sample...
I understand that is the equation. I'm comparing two different scenarios based on the same sample. Hitting the sample with something with a smaller tip will have larger pressure because all the pressure is concentrated on that little tip. Doing the same with something larger would mean less...
