This colloidal probe combines the well-known features of the proven qp-CONT AFM probes series such as high application versatility and compatibility with most commercial SPMs with a reproducible sphere radius instead of a sharp AFM tip. The excellent radius and the minimized variation of diameter provide reproducible signals.
qp-CONT AFM probes are designed for contact mode AFM imaging in air or for applications in liquid environments with a reduced thermal drift. The CONT type is also optimized for high sensitivity due to a low force constant.
The so called "Colloidal Probe Technique", where single colloids are attached with polymer glue to AFM cantilevers for force measurements, offers possibilities for a better understanding of fundamental interactions in a variety of fields. Examples are adhesion phenomena, particle-surface interactions, mechanical properties, suspensions, hydrodynamics and boundary slip - to name just some out of an increasing number of applications.
The AFM probe offers unique features:
This product features alignment grooves on the back side of the holder chip.
