Complete Solution for Nanomechanical Characterization

Comprehensive NanoMechanics

Characterize nanomechanical properties of materials ranging from extremely soft hydrated materials to stiff metals and ceramics

With thousands of peer-reviewed scientific papers and thousands of QC measurements per day in factories around the world, Bruker’s legacy of nanomechanical characterization solutions has been leading the world since our initial innovations in contact and tapping AFM technology in the 90s.

Today, Bruker's NanoMechanics Lab encompasses the full evolution of nanoscale AFM measurement techniques, including the well-established Force Volume and PeakForce QNM modes, as well as the new FASTForce Volume and FASTForce Volume Contact Resonance. Offering the most flexible force spectroscopy available, these modes can be combined to deliver huge data cubes, rendering a full array of elastic and viscoelastic data with great precision and repeatability ─ all in a single AFM system.

Calibrated Nanomechanics

The advent of Bruker exclusive probe manufacturing methods allows us to calibrate every AFM probe for spring constant and control tip shape and radius to rendering consistent high accuracy results. The new PeakForce QNM-HA product features new and easy to follow calibration steps along with expanded software capabilities in modeling and analysis to accommodate a wide variety of samples. Consistent, convenient, calibrated measurements.

Exclusive Nanoscale Mechanical Measurement Modes

PeakForce QNM PHBV and PS

PeakForce QNM

A vastly improved PeakForce QNM introduces a simple workflow to quantitatively characterize nanomechanical properties—including modulus, adhesion, dissipation, and deformation—while simultaneously imaging sample topography at atomic scale resolution. It is non-destructive to both tip and sample since it directly controls the peak normal force and minimizes the lateral force on the probe. PeakForce QNM enables routine quantifiable mechanical investigation of materials in the 1 kPa to 100 GPa range.

The combination of PeakForce QNM, precisely controlled tip geometry, and Bruker's frequency-calibrated probes enables routine measurements with the lowest uncertainty, while rendering results with high-resolution nanoscale mapping. By simply scanning the probe box QR code, selecting the specific probe number in the NanoScope software, and choosing between a touch or no-touch calibration, you're ready to start collecting truly quantitative nanomechanics measurements.

FASTForce Volume

FASTForce Volume improves the acquisition time of Force Volume mapping by >20x to measure mechanical properties of materials in the range of 1 kPa to 100 GPa. FASTForce Volume extends the operating frequency of linear ramps by > 400 Hz, closing the frequency gap between PeakForce QNM and the standard Force Volume mode. The overlap of operating frequencies facilitates nanomechanical correlative studies between modes, rendering greater measurement confidence while allowing investigation of property material frequency dependency.

FASTForce Volume CR

Contact resonance is a powerful tool for nanomechanical measurements due to its ability to measure a wide range of moduli, including both elastic and viscoelastic properties. However, until now, the implementation of contact resonance has been hampered by slow imaging speed, complex analysis, and the requirement of specialized hardware for full spectrum acquisition.

FASTForce Volume CR resolves these limitations by combining resonant and non-resonant modes to obtain the most accurate mechanical data for stiff materials in the range of <1 GPa to >300 GPa. This enhanced capability is combined with the flexible, easy-to-use software of the widely-adopted FASTForce Volume platform. In contrast to other imaging-based contact resonance methods that are essentially contact mode, FASTForce Volume CR minimizes lateral forces on the tip to reduce sample damage, tip wear, and to generate many measurements from one probe.
