Core Facility Micro- and Nanotomography (MiNa)
X-ray microtomography (μCT) is a non-destructive imaging technique that allows for the detailed visualization of the internal structure of objects at a spatial resolution down the sub-micrometer level. It uses X-rays to acquire radiographs at several thousands of rotaion angle positions, which are then reconstructed to cross-sectional images of a sample. One of the major advantages of X-ray microtomography is its ability to visualize internal features without the need to physically cut or alter the sample, preserving its integrity. This makes it particularly valuable in fields like material science, biology, and archaeology, where the internal structure is crucial for analysis. Another advantage is its high resolution, often capable of imaging at the micron or even sub-micron level, allowing for precise observation of fine details. Additionally, X-ray microtomography can provide both qualitative and quantitative data, helping researchers understand the distribution of different materials within a sample. The ability to scan a wide variety of materials, from soft tissues to hard metals, further adds to its versatility.
The Core Facility Micro- and Nanotomography (MiNa) houses four microtomography systems. Two state-of-the-art systems, namely nanotom® m (phoenix|x-ray, Waygate Technologies, Baker Hughes, Wunstorf, Germany) and Skyscan 1275 (Bruker microCT, Kontich, Belgium) have been successfully used since 2012. Two next-generation devices funded by the SNSF R'Equip and the University of Basel were installed in fall 2023: xradia 610 Versa (Zeiss, Oberkochen, Germany) and Polaris (Excsicope, Kista, Sweden).
MiNa's microtomography systems are used for a variety of research projects at the DBE, other departments of the University of Basel and the University Hospital Basel. They are also frequently used by the Natural History Museum Basel and various other institutions. In addition to users from Basel, external research groups, museums or industrial companies can also use the Core Facility. You are invited to contact the head of the Core Facility, Dr. Georg Schulz (see box on the right).
The Core Facility MiNa not only contributes to other research projects, but also carries out its own projects. These projects aim to open up new fields of application for micro- and nanotomography and to develop methods for optimizing, improving and accelerating scanning processes.
