We encourage to test our software that can greatly help in building your home made force spectroscopy Atomic Force Microscope experiment. Or it can be used to upgrade old AFM with cantilever calibration ability.
The program can be found here
It is described in Ultramicroscopy paper
and it comes together with comprehensive manual https://sourceforge.net/projects/nanopuller/files/MANUAL.pdf that includes hints on how to build your AFM for force spectroscopy and make it running.
