Bone tissue regeneration using artificial scaffolds on which bone cells, such as osteoblasts, can grow is a relatively new approach to repair bone fractures or bone decomposition due to disease. In the work presented, a simple method is introduced to make aerogels from chitosan. These could be suitable as scaffolds for bone cells.

Optimal wound healing requires restoration of the damaged tissue by formation of new tissue and epithelialization. To support this process after injury, suitable wound dressings are required to prevent development of a chronic wound. In this article, we present two recently published in vivo studies dealing with the use of chitosan-silica hybrids for wound healing.
