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.
The reflex gold coating deposited on the detector side of the cantilever covers only the free end above where the tip is located. Main advantages of the uniqprobe coating are considerably less cantilever bending and reduced drift particularly for measurements in liquid environments.
NANOSENORS qp-SCONT AFM probes are designed for contact mode AFM imaging in air or liquid environments. The SCONT type features a very low force constant offering the possibility of contact mode measurements on soft biological materials with high sensitivity.
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)
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.
