Hi Sandeep,


tipless probes have two uses that I know of, these are:

- Reference cantilevers for calibrating cantilever spring constant using the reference lever method. Tipless probes often have almost ideal beam shape dimensions and obviously no tip, this means that it is easier to calibrate them accurately and use them as reference levers. Theya re also easier to "land" another probe on because they have no tip.


-Colloid probes; microspheres can be attached to the end of the probe to study colloidal forces. This is probably their most common use.
