Who are we?

XanTec bioanalytics GmbH is a technology leader in the production of biosensors and bio-chip systems.
We provide integrated bioanalytic solutions to researchers and businesses worldwide, using our expertise in surface chemistry, biology, physics, and organic synthesis.

XanTec works closely with our customers, commercial and scientific, to develop powerful research and analysis tools tailored to their needs. We strive to provide our customers with personalized solutions which allow them to obtain optimal experimental results.



What do we do?

XanTec bioanalytics are market leaders in two main product areas:
Surface Plasmon Resonance (SPR) biosensor chips, and biological surface coatings.

Through our expertise in surface chemistry, we excel in developing innovative substrates for SPR biosensors and slide-based microarray formats. We provide innovative solutions to optimise biomolecular interaction research, protein profiling and protein assays. XanTec is involved in the entire development chain, starting from research into new applications and ending with global production and sales activities.

For individual needs, we produce and synthesize tailor-made, ready-to-use sensor surfaces and bio-conjugates. Offering the largest selection of sensor surfaces on the market, XanTec provides customers with surfaces for virtually every application. For biomedical applications, a range of biomolecular nanocoatings are offered, making plastic, glass and metal surfaces either bio-inert or specifically bio-active.

XanTec bioanalytics also offers contract research services. Through our Analytical Services group we can perform biomolecular interaction analysis and protein profiling for customers, for example in the determination of affinity constants. We are also glad to provide our expertise; assisting end-users in the development and optimisation of assays, as well as offering application advice.

Our expertise, personalised service, and hands-on approach make us a versatile and dynamic provider. Get in touch today, and find out how we can help you.

By public transport

From the main train station, “Düsseldorf Hbf”, take the commuter train on lines S28 (towards “Kaarster See”), S8 (towards “MG Hbf”) or S11 (towards “Bergisch Gladbach”) until reaching the “D-Bilk (S)” train station. Change platforms to bay 7, and then take either Bus #836 (to “D-Universität Süd”) or #836 (towards “In der Steele”) to Merowingerplatz.

By car

When travelling along the A3 from either Oberhausen or Frankfurt, change to the A46 (heading towards Düsseldorf/Neuss) at the Hilden Interchange. Alternatively, when travelling via the A57 or A59, change to the A46 (towards Düsseldorf/Neuss) at the Düsseldorf-Süd Interchange. Leave the A46 at the Düsseldorf Bilk/Hafen exit. Merowingerstrasse is a right turn immediately before the first set of traffic lights. Approximately 500 m after entering Merowingerstrasse, turn right onto Eduard-Schulte-Strasse, continue to the end (100 m) and then turn left into the Life Science Center Düsseldorf.
