The clinical laboratory industry has found a solid foothold in Hannover with particular successes in the fields of biomarker research and biomaterial development due to the growing demand for personalized medicine and advanced diagnostic capabilities. Local research institutions, such as the Fraunhofer Institute for Toxicology and Experimental Medicine (Fraunhofer ITEM) and the Lower Saxony Center for Biomedical Engineering, Implant Research and Development (NIFE), receive the necessary incentives to further research and innovations in clinical diagnostics and medical technology. The need for early disease diagnosis, personalized treatment, and precise monitoring of treatment responses has never been more crucial in both clinical routine and research. Fraunhofer ITEM’s biomarker laboratory, housed within the Clinical Research Center Hannover (CRC Hannover), is addressing this need. Directly connected to clinical departments, the biobank, and the Hannover Medical School via a pneumatic delivery system, the laboratory has taken the lead in biomarker analysis and validation. Fraunhofer ITEM’s expertise is particularly strong in lung-related biomarker analysis, including work with induced sputum, bronchoalveolar lavage fluid, and exhaled breath samples. Their research focuses not only on the customization of biomarker assays to meet specific client requirements but also on developing new analytical methods to enhance diagnostic accuracy. The other noteworthy influence in Hannover’s clinical laboratory industry comes from NIFE and its particular focus on geriatric care. As the population ages, the demand for advanced implants tailored to the needs of elderly patients is increasing. NIFE is leading efforts to develop biological, biohybrid, and biofunctionalized implants designed to replace or restore vital organ functions with long-lasting durability and biocompatibility. Through interdisciplinary cooperation with institutions like the Leibniz University Hannover and the Laserzentrum Hannover, NIFE is at the forefront of biomaterials production. Their research spans the development of synthetic and biological materials for implants, as well as smart materials for targeted functionalization.
