The NANOSENSORS uniqprobe combines the well-known features of the other NANOSENSORS AFM probe series such as high application versatility and compatibility with most commercial SPMs with the additional advantage of a strongly reduced dispersion of force constant and resonance frequency.

The unsurpassed uniformity of the mechanical characteristics of the uniqprobe series is particularly important for applications, where a large number of probes with known and near identical force constants or resonance frequencies are needed. The sensors of the uniqprobe series are especially adapted for molecular biology, biophysics and quantitative nano-mechanical studies.

NANOSENORS qp-BioT AFM probes are designed for contact mode or dynamic mode AFM imaging in air or liquid environment. These probes feature two different triangular cantilevers on one side of the support chip. The uniqprobe BioT type offers an alternative to silicon nitride probes, with the advantage of taller tips with smaller opening angles and reduced drift.

The probe offers unique features:

  • small dispersion of force constant and resonance frequency 
  • typical tip height 7µm 
  • typical tip radius of curvature smaller than 10nm
  • stress free cantilevers with considerably less bending
  • tip and cantilevers are made of a quartz-like material
  • reduced drift for applications in liquid environments
  • tip repositioning accuracy of better than ± 8 µm (in combination with Alignment Chip)
  • chemically inert

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

A chromium/gold layer of about 60nm is partially coating the cantilever on the detector side near its free end where the tip is situated. The main advantages of this partial metallic coating are considerably less cantilever bending and reduced drift for SPM measurements in liquid environments.
