III. Research Interests
The main focus of research of Prof. Lehr’s team over the past 15 years has been on the one hand exploring biological barriers - in particular of the gastro-intestinal tract, the skin and the lungs -, and on the other hand developing the appropriate carriers capable of crossing these epithelial barriers to deliver an active molecule to its target. The expansion of this approach by developing new in vitro models of higher sophistication and relevance, based on the epithelial cells and tissues concerned, is in advanced progress. In parallel, the nanotechnology approach is improving and broadened in terms of formulating multifunctional nanocarriers that allow targeting the site of action, release the payload in a controllable manner and last but not least being safely biodegraded and excreted from the body.
