Efficiency and Environmental Properties of Nanomaterials

Nanotechnology is used systematically to endow products with defined features. We are specialized in investigating free nanomaterials, but also products with properties based on the application of nanomaterials.

In order to characterize the environmental properties of free nano-objects and explore their potential effects on the environment we conduct experimental studies. The range of methods we employ covers standard tests based on international guidelines (e.g. OECD) and extends through to comprehensive studies on very complex issues. Since meaningful simulation experiments, in particular, are often not standardized, we offer to design simulation experiments tailored to clients’ specific problems. All studies can be carried out under GLP conditions.

For comparative demonstration of the photocatalytic activity of self-cleaning surfaces or air-cleaning surfaces, methods standardized according to ISO have been established. Examples are the detection of antibacterial activity (ISO 27447) or the reduction of nitrogen oxides from the air (ISO 22197-1). We also develop special measuring devices for specific problems.

With our expertise we contribute to the development of guidelines and guidance documents. Due to committee work (see below) and involvement in many joint projects we are familiar with current developments in the context of research and standardization which we consider in our project work.
