Hi SPMers! I have experienced remarkable height differences while imaging biological samples in regular tapping vs. Peak Force tapping. Height is always smaller in tapping, I guess that due to the higher vertical force exerted by the tip; Nevertheless, I would be really grateful if any of you could give me the reference of any publication covering this

Hi! I would like to perform IV curves on a certain conductive sample while applying a constant vertical force. I have determined the Young's modulus of the sample to be around 1-3GPa. The fact is that I would like to measure the IV curve while effectively deforming the sample in the elastic regime. To do that, I guess I need a wear resistant AFM

Hi everybody, I am searching for an old multimode optical stage. As I will replace the laser and photodetector, it does not matter if it does not work properly, I am just interested in the metallic chassis. Thanks in advance!
