Enabling first-and-only AFM capabilities with highest performance

Optimized Configurations for Advanced Research

XR Nanomechanics

XR Nanomechanics provides a range of modes to comprehensively detect the smallest structures with spatial resolution down to sub-molecular units of polymer chains. Researchers correlate nanomechanics data to bulk DMA and nanoidentation methods with our proprietary AFM-nDMA™ mode. Achieve quantifiable nanoscale characterization extending from soft sticky hydrogels and composites to stiff metals and ceramics.

XR Nanoelectrical

Dimension XR Nanoelectrical configuration covers the broadest array of electrical AFM techniques in a single system. Researchers capture electrical spectra in every pixel correlated with mechanical property measurements with the proprietary DataCube modes. This system delivers previously unattainable information from a single measurement.

XR Nanoelectrochemical

The nanoelectrical configuration enables robust AFM-based scanning electrochemical microscopy (AFM-SECM) and electrochemical AFM (EC-AFM). AFM operators acquire electrochemical information with <100 nm spatial resolution and perform simultaneous electrochemical, electrical, and mechanical mapping in a single system.

Highest Resolution for All Modes, All Environments

From point defects in liquid and stiffness maps to atomic resolution in air and conductivity maps, Dimension XR systems deliver highest resolution in all measurements. They utilize Bruker’s proprietary PeakForce Tapping technology to achieve both hard and soft matter performance benchmarks, including crystal defect resolution and molecular defects in polymers. The same technology plays an equally important role in resolving the smallest asperities on roughened glass over hundreds of images. The systems combine PeakForce Tapping with extreme stability, unique probes technology, and Bruker’s decades of experience in tip scanning innovation. The result is highest resolution imaging consistently, completely independent of sample size, weight, or medium – and for any application.

Revolutionary AFM-nDMA

For the first time an AFM can provide complete and quantitative viscoelastic analysis of polymers at the nanoscale, probing materials at rheologically relevant frequencies, in the linear regime. Proprietary dual-channel detection, phase-drift correction, and reference frequency tracking enable a small strain measurement in the rheologically relevant 0.1 Hz to 20 kHz range for nanoscale measurements of storage modulus, loss modulus, and loss tangent that tie directly to bulk DMA.

Proprietary DataCube Modes

These modes utilize FASTForce Volume to perform a force-distance spectrum in every pixel, with a user-defined dwell time. Using high data capture rates, a multitude of electrical measurements are performed during the dwell time, resulting in electrical and mechanical spectra at every pixel. DataCube modes provide full characterization in a single experiment, which is unheard of in a commercial AFM.

Dimension XR's DataCube modes provide multidimensional nanoscale information at every pixel, simultaneously capturing in a single measurement both electrical and mechanical characteristics.

Exclusive PeakForce SECM

With a spatial resolution less than 100 nm, this mode redefines what is possible in the nanoscale visualization of electrical and chemical processes in liquid. PeakForce SECM dramatically improves, by orders of magnitude, the resolving power over traditional approaches. This enables entirely new research into energy storage systems, corrosion science and biosensors, opening the door to novel measurements on individual nanoparticles, nanophases, and nanopores. Only, PeakForce SECM provides simultaneous capture of topographic, electrochemical, electrical, and mechanical maps with nanometer-scale lateral resolution.


AFM Modes

Expand Your Applications with AFM Modes

With an unrivalled suite of imaging modes available, Bruker has an AFM technique for every investigation.

Built on the backbone of core imaging modes—Contact Mode and Tapping Mode—Bruker offers AFM modes that allow users to probe their samples’ electrical, magnetic, or materials properties. Bruker’s innovative new PeakForce Tapping technology represents a new core imaging paradigm that has been incorporated into several modes, providing topographic, electrical, and mechanical properties data in parallel.
