Re: Maximum indentation depth using the AFM in contact mode

Ben and Alex: First of all, thank you very much for your responses. I am new to AFM technology and I really appreciate the time you've taken. Let me clarify a couple of things. 1. I am using a soft cantilever because to get good force-displacement curves, the stiffness of the cantilever should match the stiffness of the tissue being indented. In

Maximum indentation depth using the AFM in contact mode

Greetings: I am using the AFM (Veeco NS 5, multimode scope) to indent soft biological tissues. I intend to use a soft cantilever (nominal stiffness = 0.01 N/m) with a 10 micron diameter glass or polystyrene particle attached to it (Novascan, Inc). I am looking for force-displacement curves to get the tissue stiffness. I would like to know how deep into
