Being the first super-resolution microscopy technique the STED method revolutionized the light microscopy. With the nanorulers from the GATTA-STED series now adequate calibration probes are finally available. The single color nanorulers carry two fluorescent marks out of dense arrangements of the high quantum yield dye ATTO 647N. We offer the mark-to-mark distances in the sizes 50 nm, 70 nm, 90 nm and 120 nm. In addition we offer a new design containing three emitting points with two different fluorophores which allows the acquisition of very eye-catching images. The multicolor nanoruler with three emitting points is available with the size of 140 nm (ATTO 647N & ATTO 594).

On request we can also design special solutions for your specific requirements. All nanoruler samples will be delivered on a sealed glass slide which you can comfortably put directly on your microscope.
