Modern healthcare increasingly relies on advanced biomaterials that can support tissue repair and regeneration while reducing the need for invasive treatments. Hydrogels, which are water-rich polymeric materials that closely resemble the natural extracellular matrix of living tissues, have emerged as promising candidates for applications such as wound healing, drug delivery, and tissue engineering. In particular, cartilage regeneration remains a major clinical challenge because cartilage has a very limited capacity for self-repair, often leading to chronic pain, reduced mobility, and an increased risk of osteoarthritis. However, many currently available hydrogels suffer from limited mechanical stability, insufficient control over their physical and biological properties, or crosslinking methods that may compromise biocompatibility and hinder clinical translation. At the same time, there is a growing demand for sustainable biomaterials derived from renewable natural resources that support both advances in healthcare and the European transition towards a circular bioeconomy.
ClickBioGel addresses these challenges by developing bio-based hydrogels using highly efficient click chemistry reactions which will enable the formation of precisely controlled polymer networks under mild and cell-friendly conditions. By functionalizing naturally derived polymers and optimizing their crosslinking chemistry, ClickBioGel allows the fabrication of multi-component hydrogels with improved mechanical performance, stability, and biological functionality. The project aims to create biomaterials that better mimic the native tissue environment and provide suitable support for cell growth and tissue regeneration, with a particular focus on cartilage tissue engineering.
Beyond the scientific objectives, ClickBioGel aims to strengthen European excellence in biomaterials research by integrating expertise in polymer chemistry, materials science, and biomedical engineering. The project's outcomes contribute to the development of safer, more sustainable, and more effective biomaterials for regenerative medicine and have the potential to support future therapies for cartilage repair and other tissue engineering applications. More broadly, the project aligns with European priorities by advancing sustainable healthcare technologies, promoting innovation in bio-based materials, and contributing to improved quality of life for patients with degenerative tissue disorders.
