The Integrative Cartilage Research Group at the University of Melbourne researches links between microstructure, mechanics and biological signalling networks.
Micro-CT is a valuable imaging technology for visualising structure, however objects of interest need to absorb x-rays in order to be seen. For many soft biological materials, including tissue-engineered scaffold materials, this is not the case. In this project, the goal is to investigate and develop contrast agents for visualising soft biological tissues and scaffold materials; for example, cartilage, ligament and tendon.
Contrast agent requirements include:
- visualisation and delineation of soft tissues and scaffold materials with microCT
- biocompatible (cells and tissues)
- easily introduced (injection, immersion) and rinsed out
- highly-reproducible synthesis
The project involves monitoring of biosignals and biomarkers in biological constructs. The work requires a creative approach to developing new protocols for evaluating biological and mechanical signalling networks in tissues.
