Colloidal probe, AFM cantilever with round tip like a ball.


The new sQube® colloidal probe combines the well-known features of the proven NANOSENSORS™ NCH series such as high application versatility and compatibility with most commercial SPMs with a reproducible sphere radius instead of a sharp tip. The excellent  radius and the minimized variation of diameter provide reproducible signals.

NCH AFM probes are designed for non-contact mode or tapping mode AFM (also known as: attractive or dynamic mode). 

The so called "Colloidal Probe Technique", where single colloids are attached to AFM cantilevers for force measurements, opens the chance 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 probe offers unique features:

        - sphere material: Polystyrol
        - excellent sphere diameter A = 1,98 µm, B = 3,6 µm, or C = 6,1 µm (all +/- 5%)
          (Due to different masses the resonance frequency can differ.)
          Please choose A, B, or C by ordering!
        - highly doped cantilever to dissipate static charge
        - chemically inert
        - high mechanical Q-factor for high sensitivity
        - precise alignment of the cantilever position (within +/- 2 µm) in conjunction with the usage
        of the alignment chip
        - compatible with PointProbe® Plus XY-Alignment Series
