Life Science

Life Science

Several active substances/medicines have to be released continuously over a long period of time or have to be delivered specifically to the site of action. This is necessary in order to achieve the best possible effect or to reduce possible side effects. Surflay develops drug delivery systems. We are also engaged in the coating of medical devices (e.g. stents).

Water industry

Water industry

Water is a valuable commodity, especially in times of drought and in areas with low water resources. In addition, the manufacturing industry in many industries requires thousands of cubic meters of fresh water, which must then be purified again. We develop novel membrane technologies together with our partners from the water industry.

Today, agriculture faces enormous challenges. On the one hand, farmers have to work as productively and economically as possible, and on the other hand, they are required to produce in an ecologically sustainable way. Surflay can support agriculture with innovative encapsulation techniques for pesticides, herbicides or fungicides.

Contract research

Are you looking for reproducible methods to modify, functionalize or characterize surfaces?

Does the word "encapsulation" catch your attention?

Are you looking for solutions based on polymers, biosensors, nanoparticles?

My team and I work with Surflay already since 2015, where they developed customized temperature sensitive beads for us. We had been looking already for a long time for beads incorporating one temperature sensitive and one insensitive dye to expand our volumetric astigmatism particle tracking to reliable temperature measurements. Due to the good communication and the profound knowledge in bead synthetization of Dr. Dähne the development was quickly completed.

The technique has also drawn the attention of the attendees of the first ‘Short Course on Practical Microfluidics’ at TU Ilmenau (, where the products of Surflay were displayed and will be used in practical lab sessions in the future.

The nanoparticles developed by Surflay are particularly suitable for use in lateral flow assay (LfA) applications. Surflay has succeeded in producing nanoparticles that meet all requirements. Innovative proposed solutions and application-specific adaptations were implemented in the shortest possible time. For this purpose, the particles were extensively characterized by a wide range of analytical methods, whereby the targeted target characteristics were achieved.

The very good cooperation between Surflay and us is the basement for the successful processing of the interdisciplinary project. Our experience shows that Surlfay understands interdisciplinary issues and analyzes them extremely competently and then successfully implements them. We can rely on consistently high quality, maximum adherence to deadlines and flexible reactions to application-related changes. We also benefit from the proactive cooperation with ideas and suggestions for improvement and can therefore recommend Surflay as a partner for your applications.
