Bioinspired nanomaterials

Johannes Raff

Department for Biogeochemistry
Forschungszentrum Dresden Rossendorf

Protecting the environment and saving resources are two of the society\u2019s challenges of the 21th century. Therefore interesting insights coming also from nature. As many bacteria and archaea live in extreme habitats, they developed early in evolution so called surface layers (S-layers), which function as intelligent interface between cells and their environment. One function of such S-layers is the binding of toxic metals and metalloids and thusly the protection of the cells from being damaged by these elements and their compounds. This makes, together with their self-assembling properties, S-layer very interesting building blocks for the construction of new bioinspired nanomaterials for different technical applications. Currently under development are materials for the selective metal-binding for the removal of toxic metals and metalloids or the recovery of precious metals, highly efficient (photo)catalysts for the elimination of organic pollutants or organic synthesis and new biosensors for chemicals or pharmaceuticals.

Brief Bio:

Diploma degree in Microbiology from the University of Bayreuth and PhD in Biochemistry in 2002 from the Institute of Biochemistry, University of Leipzig. The study was performed at the Institute of Radiochemistry, Forschungszentrum Dresden-Rossendorf, focusing on the interaction of heavy metals with bacterial surface layer proteins and their technical application. The PhD thesis was awarded in 2002 with the PhD prize of the Forschungszentrum Dresden-Rossendorf, and further ideas for an application as metal selective filter materials in 2007 as best business idea within the business-plan competition futureSAX. Since 2007 senior scientist at the Institute of Radiochemistry and coordinator of several projects in the field of radioecology and bionanotechnology with the topics interaction of actinides with bioligands and application of bacterial surface layers as technology platform for the development of new filter materials, (photo)catalysts and sensors.
