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:
The samples are shipped in solution. The amount of material is sufficient for at least 10 AFM surfaces, densely packed with DNA‑origami structures.
