JPK has unveiled the NanoTracker 2 optical tweezers system for quantitative measurements.
JPK launched the NanoTracker 2 optical tweezers system at the 2013 Biophysics Annual Meeting held in Philadelphia, earlier this week.
The NanoTracker 2 is an optical tweezers platform based on research-grade inverted optical microscopes and designed for sensitive manipulation, force and tracking experiments
JPK has enabled new open routines for the user to design their own enhanced measurements. It also provides new force clamp and signal multiplexing and de-multiplexing capabilities by utilising acousto-optic deflectors which spatially control the optical beams.
The new system comes with an overall improved performance especially for the beam steering through highly accurate pivot-point piezo mirrors and the detection system which benefits from a complete redesign of the optical pathway.
The resulting better linearity and diminished crosstalk improve all sensitive force measurements. New functions are also implemented for a more precise trap calibration which allows the extraction of additional material properties.
Features overview:
- 3D force measurements with femto-Newton sensitivity and sub-nm precision
- Highest stability and lowest noise level for the most accurate measurements
- Simultaneous fluorescence imaging
- Powerful, flexible control and data analysis software
- Class 1 laser certified
- Flexible, modular design for applications ranging from single-molecules to living cells
