Cancer is difficult to treat due to its early immune invasion and metastasis. In the study presented here, the frequently used chemotherapeutic drugs 5-flourouracil and cisplatin are encapsulated in TPP cross-linked chitosan nanoparticles and their in vitro anti-cancer effect is investigated.

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.
