Ensuring clean systems in a sustainable manner

Sustainable solutions for clean surfaces and water-carrying systems are becoming increasingly important. It has been clear for some time – not just since the COVID-19 pandemic – that microbial contamination – including that caused by antibiotic-resistant bacteria – poses a major challenge. Innovative solutions are needed in both the medical sector and in water-carrying systems: The focus is on two developments: durable, multifunctional surfaces with easy-to-clean or antimicrobial properties, as well as efficient, chemical-free cleaning systems with high environmental compatibility.

Multifunctional surfaces and innovative cleaning systems

At Fraunhofer IST, we develop customized solutions for multifunctional surfaces that possess properties such as antimicrobial or dirt-repellent capabilities. We offer comprehensive surface analysis capabilities, which allow us to characterize, among other things, coating composition, stability, wetting behavior, and microbiology. In addition, we are developing new cleaning systems and sensors at IST. This includes the in-situ production of, for example, ozonated water, as well as the development of plasma sources for the generation of plasma-treated water, which can be integrated into robot-guided and mobile systems, for instance.

We offer you the optimal cleaning solution for your requirements

We develop functional surfaces and customized, integrable cleaning systems for you which are optimally adapted to your products. Benefit from our expertise along the entire process chain using modern plasma and electrochemical processes.

Plasma-activated water

Fraunhofer IST investigates chemical-free disinfection method

Joint study is published

Production, shelf life and surface sanitizing efficacy of plasma-treated liquids

In times of increasingly stringent hygiene and food-safety requirements, the need for effective but simultaneously environmentally-friendly disinfection methods is growing. One possible alternative to conventional disinfectants is provided by plasma-activated water. The Fraunhofer Institute for Surface Engineering and Thin Films IST, in collaboration with the Fraunhofer Institute for Electron Beam and Plasma Technology FEP, has investigated the effectiveness and durability of this innovative solution, and has summarized the results in a study.
