The NanoWorld PNP-TR-TL-Au AFM probes feature two different triangulasr tipless cantilevers made of silicon nitride with nominal force constants of 0.32 and 0.08 N/m.
The AFM cantilevers have an overall gold coating. The holder chip that is made of Pyrex.
NB: We glue a colloidal microsphere only on one of the AFM cantilevers. You can choose whether you want the microsphere glued to the long or the short AFM cantilever
NB: Colloidal AFM probes based on PNP AFM cantilevers have complex behavior that is strongly dependent on ambient temperature and humidity, often leading to AFM cantilever bending and AFM cantilever torsion. For this reason we strongly recommend using colloidal AFM probes based on qp-CONT or qp-SCONT AFM cantilevers for all applications that require very soft AFM cantilevers and/or operation in fluids. We do not guarantee the integrity or functionality of PNP-based colloidal probes.
NB: Please note that colloidal AFM probes based on PNP AFM cantilevers are not suitable for application in fluids.
