CP-NCH-SiO

Product Description:

This 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.

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 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.

• sphere material: silicon dioxide (SiO₂)
• excellent sphere diameter: A = 2 µm, B = 3.5 µm, C = 6.62 µm, D = 10.2 µm, or E = 15 µm (all +/- 5%)
  (Due to different masses the resonance frequency can differ.)
  Please choose A, B, C, D, or E  when ordering!
• highly doped silicon cantilever to dissipate static charge, chemically inert to most common solvents
• high mechanical Q-factor for high sensitivity
• precise alignment of the cantilever position when used together with the Alignment chip (within +/- 2 µm)
