Nanosurf

It is our pleasure to mention Nanosurf as a user example, where GATTAquant products are used to test the performance of their high-end atomic force microscopy products (AFM).

Using the DriveAFM – one of the most high-fidelity AFMs for biological samples available – GATTA-AFM nanorulers were imaged in WaveMode in liquid environment.

It proved easy to obtain high-resolution images at high imaging speeds with minimum lateral forces, thanks to WaveMode’s pico-newton level force control.

High resolution images allowed easy determination of the substructural ladder shape of the DNA origami rectangles with a ladder step width of 6 nm and the typical height of 2 nm for double-stranded DNA. The image was acquired with a WM0.1Au probe.
