Research

The Soft Matter Synthesis Laboratory (SML) is a synthetic platform (founded in 2011) of the BioInterfaces Technology and Medicine Programme (BIFTM Programme). It is located in Building 601 at the Campus North of the KIT.

The Soft Matter Lab consists of a pool of competence in chemistry, including Organic Chemistry, Polymer Chemistry and Materials Chemistry, underpinned by the expertises of Prof. Stefan Bräse (Institute of Organic Chemistry), Prof. Patrick Théato (Institute for Chemical Technology and Polymer Chemistry), and Prof. Jörg Lahann (Institute of Functional Interfaces).

The main goal of the Soft Matter Synthesis Laboratory is to intellectually and experimentally support projects at the interface of Biology, Chemistry and Physics. The activities of the laboratory thus span the development of novel synthetic strategies, advanced materials design as well as optimization studies and on-demand synthesis within the BIF program.
