Company Profile

ATTO-TEC GmbH was founded in autumn 1999 as a spin-off of the University of Siegen. The decisive factor was the scientific experience of the four founders with organic laser and fluorescent dyes, some of which lasted decades.

In particular, Prof. Drexhage's research team focused on the synthesis and development of long-wavelength fluorophores for the labeling of biomolecules in the 1990s, as fluorescence-based techniques were established as sensitive detection and analysis methods in the emerging field of life sciences. Thus, in the summer of 2000, the young company was able to present its own market-ready products as a manufacturer of fluorescent dyes for medicine, diagnostics and biology at ACHEMA in Frankfurt am Main.

Through the constant development of innovative derivatives - e.g. compounds for "click chemistry" or dye-conjugated phospholipids - the market position was further strengthened. In the early years, important impulses for application-oriented dye research were obtained by participation in various BMBF and EU projects.

After almost 20 years of existence, ATTO-TEC GmbH now has a portfolio of more than 40 fluorophores with over 200 different modifications. These partially patented fluorescence markers cover the entire visible spectral range from ultraviolet to near infrared.

Our customers - including renowned research institutes and international companies - appreciate the particularly high purity and excellent quality of our ATTO dyes.
In addition to our readily available catalogue products, we offer the service of individual customer syntheses. In close cooperation with the client, our qualified team develops tailor-made dyes or derivatives for its special application.

The satisfaction of our customers is our top priority. Please do not hesitate to contact us if you have any problems or questions regarding our particular products as well as fluorescence or organic dyes. We will be glad to help you!
