Biological research services

In our modern Bio-laboratory, we accompany material-developments with functional tests to bioactive and antimicrobial effects as well as with biocompatibility testing. We investigate new materials on activity against human pathogenic bacteria and fungi, and support the development of cosmetic and medically effective innovative products with tests on antioxidant properties and cytotoxicity.
