Nanomechanical Characterization Modes

Understand the physical properties of molecules, composites, and nanostructures

Measuring and mapping mechanical properties at the nanoscale are a key requirement across many industries. Applications range from novel two-dimensional materials to plant and animal cells. Bruker’s comprehensive nanomechanical modes deliver complementary characterization techniques for greater flexibility and deeper insights when examining simple or complex sample types.

These nanomechanics capabilities include Bruker’s revolutionary PeakForce QNM® with PeakForce Capture™, and Fast Force Volume, ensuring unparalleled force control across a broad set of frequency ranges. These features can be applied to samples from extremely soft biological materials (~1 kPa) to  metals (>100 GPa). The modes operate in ambient, fluid, gas, and glovebox environments, and can additionally track mechanical properties as a function of sample temperature.  They enable the unprecedented capability to obtain highest resolution (to atomic scale) property mapping, including modulus, deformation, and adhesion, while simultaneously imaging sample topography.

 

Uniquely, PeakForce QNM® seamlessly integrates with Bruker’s PeakForce TUNA™ and PeakForce KPFM™ to simultaneously map nanomechanical properties with nanoscale electrical conductivity and surface potential imaging, respectively.
