How to optimize AFM scan parameters gear icon

This colloidal probe combines the well-known features of the proven NANOSENSORS™ 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. 

CONT AFM probes are designed for contact mode (repulsive mode) AFM imaging. This sensor can also be used for force-distance spectroscopy mode or pulsed force mode (PFM). The CONT type is 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:

  • sphere material: gold (Au)
  • sphere diameter A = 1.5 µm - 3 µm, B = 3 µm - 5.5 µm, or C =  5.5 µm - 9 µm, all typical values
    (Due to different masses the resonance frequency can differ.)
    Please choose  A, B, or C when ordering!
  • highly doped silicon AFM cantilever to dissipate static charge, chemically inert to most common solvents
  • high mechanical Q-factor for high sensitivity
  • precise alignment of the AFM cantilever position when used together with the Alignment chip (within +/- 2 µm)
  • compatible with PointProbe® Plus XY-Alignment Series

This product features alignment grooves on the back side of the holder chip.
