Biological characterization of antimicrobial and photocatalytic surfaces

At Fraunhofer IGB, we have developed standardized microbiological evaluation methods and adapted them to different questions in order to check the hygienic status of technical surfaces or to evaluate antimicrobial effective material surfaces.

Various test methods are available at Fraunhofer IGB, which are used depending on the question or are combined with one another. On the basis of microbiological, process engineering and / or molecular biological methods, test methods are also developed and established. This also includes the construction of technical test structures for application-oriented investigations.

Testing antimicrobial surfaces

Antimicrobial surfaces have a growing demand. In health care, for example, high expenditure is caused by bacteria-induced dental diseases. The biofilms established in the oral area are particularly dangerous because they can not only cause tooth damage, but can also penetrate other organs.

New antimicrobially effective materials for the dental field

In a successful collaboration between Fraunhofer IGB and the Fraunhofer Institute for Silicate Research (ISC), innovative, antimicrobially effective materials were developed for dental use. Fraunhofer IGB provided the microbiological evaluation methods in order to be able to prove the biological effect of the materials.

Evaluation of antimicrobially effective polymers

The existing microbiological evaluation methods have been further developed for antimicrobially effective plastics, a major focus of the Fraunhofer Polymer Surfaces Alliance POLO, so that microbial growth can now be captured on flat shaped bodies both qualitatively and quantitatively.
