NanoTracker 2

Optical tweezers / trap for quantitative force measurements

The Bruker JPK NanoTracker 2 is an optical tweezers system for research-grade inverted optical microscopes, for manipulation, force and tracking experiments.

  • 3D force measurements with femto-Newton sensitivity and sub-nm precision
  • Trap and track particles from several ┬Ám down to 30nm
  • Control, manipulate and observe samples in real time
  • Simultaneous fluorescence imaging
  • Class 1 laser certified
  • Modular system for applications from single-molecules to living cells

With the NanoTracker you can measure particle/cell interactions and collect data about single molecule mechanics. You can also determine the mechanical characteristics including adhesion, elasticity and stiffness of single molecules. More info…

Technical Details

The Bruker JPK NanoTracker 2 is capable of detecting the smallest forces and manipulating particles and molecules with the highest precision. Noise levels are extremely low, with laser stabilisation and specially designed detection electronics in the head. The compact folded design of the laser beam path minimises drift.

Flexible Options

There are various options to suit your applications:

  • Double-beam configurations
  • Multi-beam configurations
  • Combined solutions for coarse and extra precise sample positioning
  • Various beam steering options
    • Including pivot-point piezo-driven mirrors and fast acousto-optic deflectors (AODs)

Freedom of Movement

The traps can be steered individually through the sample in 3D. Sample positioning can be controlled precisely, with the additional option of a closed-loop piezo sample stage. The laser power of each trap can be controlled independently.

This freedom opens up the potential for a wide range of experimental assays and geometries.
