High-resolution imaging with extreme performance

The NanoWizard® 4 XP BioScience atomic force microscope combines atomic resolution and fast scanning with rates of up to 150 lines/sec and a large scan range of 100µm in one system. It is designed to provide highest mechanical and thermal stability on inverted optical microscopes during long term experiments on samples ranging from single molecules to living cells and tissues.

The image shows atomic lattice of mica in buffer, taken in closed-loop on an inverted microscope.

The NanoWizard 4 XP BioScience comes with:
  • PeakForce Tapping® for easy imaging
  • Fast Scanning option with up to 150 lines/sec
  • NestedScanner Technology for high-speed imaging of surface structures up to 16.5µm with outstanding resolution and stability
  • New tiling functionality for automated mapping of large sample areas
  • V7 Software with revolutionary new workflow-based user interface
  • DirectOverlay™ 2 software for perfect integration and data correlation with advanced fluorescence microscopy platforms
  • Vortis™ 2 controller for high-speed signal processing and lowest noise levels

Automated mapping of large sample areas with new tiling functionality

The HybridStage™ or Motorized Precision Stage transforms experiments by enabling direct access to a large sample area, with automated, motorized movement to selected positions, grids and mapping regions. Begin with the DirectOverlay 2 optical calibration, and then select a region for optical tiling up to millimeters in size.

Precise motor movements automatically bring the whole sample into view, making it easy to select regions and features for further investigation. A single click navigates from point to point or MultiScan experiments automate a sequence of measurements at selected points.

The feedback correction signal images highlight the surface membrane features, particularly in the zoomed image. Microvilli dominate the center of the cell, with membrane ruffles at the cell boundary.

The NanoWizard 4 XP, with its unique tip-scanning technology and fast imaging capabilities, is ideal for taking advantage of the synergy between AFM and super-resolution microscopy. The NanoWizard 4 XP is compatible with a wide range of platforms, such as those from Zeiss (PALM/STORM, SIM), Leica (STED), PicoQuant(STED), Nikon (SIM, STORM) and Abberior (STED). The 980nm laser option for the AFM head allows the simultaneous use of optical microscopes and focus stabilization systems, critical for long term experiments, and avoids conflicts with fluorescence or spectroscopy measurements.

Outstanding quantitative data from molecules, cells and tissues

QI™ Advanced, based on real force curves, offers both astounding speed and resolution for applications ranging from single molecules to living cells. The quantitative data allows precise and fast analysis of mechanical or biochemical interactions, e.g., localization of binding sites, directly overlaid with fluorescent labelling and topography with Molecular Recognition Imaging. Advanced batch processing options include multiple models for modulus fitting and can reveal surface topography at zero force with Contact Point Imaging (CPI).

Note, that the detachment of the cell from fibronectin results in a very large pulling range of 77 µm.
