Spraymatiq’s key innovation is the development of synthetic biofilms based on hydrogels. This artificial matrix enables the targeted immobilization of microorganisms and at the same time offers control over key parameters such as cell density, biofilm volume or conductivity.

Compared to natural biofilms, the synthetic approach allows significantly improved process control. In bioelectrochemical systems, for example, increased productivity has been demonstrated – published and secured by a patent (Knoll et al., 2022).

In addition, synthetic biofilms are highly resilient to external disruptive factors such as radiation or chemical contaminants. The symbiotic growth of different microorganisms creates synergistic effects in the metabolic pathways, making it possible to realize complex reactions in the smallest of spaces. In this way, toxic intermediate products can be avoided and additional energy input can be reduced – thus significantly lowering both process and investment costs.

Another key to technical implementation is our form of application: the biofilms are applied using a specially developed spray system. This allows them to be applied to technical surfaces quickly, reproducibly and over a large area – a clear advantage for integration into existing processes. Different morphologies or co-substrates can also be applied in a targeted manner.

Even though many microorganisms are fundamentally capable of forming biofilms, the knowledge required to specifically promote these processes is often lacking. With sprayable biofilms, robust, functional biofilm systems can be created in a fraction of the usual time – and on almost any scale.
