Special handling information for NANOSENSORS™ uniqprobes

Due to their unique geometry the tips of the uniqprobes are more susceptible to tip damage by electrostatic discharge (ESD) than other Silicon-SPM-Probes.

Electric fields near the probe chip may lead to field evaporation which can blunt the tip apex of the probe tip. Therefore the NANOSENSORS™ uniqprobes are shipped in specially designed ESD-safe chip carriers.

NANOSENSORS™ recommends to their customers to take appropriate precautions to avoid tip damage due to electrostatic discharge when handling the probes. This can for example be done by using anti-electrostatic mats, wrist bands and tweezers.

NANOSENSORS™ uniqprobe AFM Probes series

uniqprobe - HeartBeatCantilever – for ScanAsyst** and Peak Force Tapping**

NANOSENSORS™ qp-HBC AFM probes are designed for use in ScanAsyst® or PeakForce Tapping™** in air. The qp-HBC probes are also compatible for contact and non-contact or soft tapping mode AFM imaging The combination of soft AFM cantilever and fairly high resonance frequency enables stable and fast measurements with reduced AFM tip-sample interaction.

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 AFM probes with known and near identical force constants or resonance frequencies are needed.

**PeakForce Tapping™ and ScanAsyst® are registered trademarks of Bruker Corporation.

The AFM probe offers unique features:

  • compatible for use in ScanAsyst® or PeakForceTapping™** in air 
  • small dispersion of force constant and resonance frequency
  • circular symmetric AFM tip shape with a hyperbolic profile
  • typical AFM tip height 7µm 
  • typical AFM tip radius of curvature smaller than 10nm
  • Al coating on detector side of AFM cantilever
  • AFM tip and AFM cantilevers are made of a quartz-like material
  • alignment grooves on backside of silicon holder chip
  • AFM tip repositioning accuracy of better than ± 8µm (in combination with Alignment Chip)
  • chemically inert
This AFM probe features alignment grooves on the back side of the holder chip. These grooves fit to the NANOSENSORS Alignment Chip.
