The “Bio- and Nanotechnology“ department at Fraunhofer IKTS offers materials, nondestructive testing techniques, and characterization methods combining materials science, immunobiology, and materials diagnostics. Scientists at the sites in Dresden, Hermsdorf, and Leipzig undertake applied research in bio- and nanotechnology to speed up development of marketable solutions for immunobiology, cell production, and medical technology. The department also develops acoustic and optical test systems for all materials classes in production monitoring and control. Extensively equipped laboratories and pilot-plant facilities ensure the efficiency and quality of the development process.
One of the department's core research activities is characterization of materials and components in terms of geometry, material defects (cracks, blowholes, pores, delamination, etc.), mechanical stresses, hardness, microstructure, and other features on a macroscopic to nanoscopic scale. Various methods – e.g., acoustic pattern recognition, atomic force acoustic microscopy, ultrasonic microscopy and laser ultrasonics, optical coherence tomography, and ellipsometry as well as other spectroscopic methods – are used. Special focus is on additive manufacturing. With integration of testing and process monitoring technologies developed at Fraunhofer IKTS, additive manufacturing processes can reach their full potential for bottom-up production of one-offs.
Another core activity is development of technologies and processes for characterization of (immuno)biological properties of implant materials and medical devices. With the help of non-destructive measurement and diagnostic methods, information on interactions between biological and artificial materials can be utilized to improve mechanical stability, service life, and biocompatibility. Materials development and measurement technology are combined to yield novel approaches that can generate considerable added value in all areas of life sciences.
