GATTA-AFM 3D NANORULER

AFM images can be influenced by the form of the tip. These distortions can be corrected by using our GATTA-AFM 

3D nanoruler as a calibration tool with a well-defined and known morphology for blind tip reconstruction.

The design with sharply defined steps of different heights and a height profile well matched for use with a broad 

range of macromolecular complexes (up to 20 nm).

It combines several characteristics that make it well-suited for blind tip reconstruction:

Its designed structure contains flat faces in the x-y direction and sharp edges in the z direction, creating a four-step 

staircase from 2 to 20 nm.

Consisting of DNA, it is fully biocompatible and can be facily deposited on surfaces alongside other biological 

macromolecules and imaged both dry and in liquid.

The above combination of features enables the nanoruler’s application for straightforward AFM image correction 

for a wide range of 3D nanostructures.

The samples are shipped in solution. The amount of material is sufficient for at least 10 AFM surfaces, densely packed

with DNA‑origami structures.
