Additive manufacturing - especially 3D printing of hydrogels - requires materials that are not only formable and biocompatible but also precisely tunable. A recent study investigated hydrogels based on chitosan, graphene, and titanium dioxide to optimize printability and shape fidelity.
Innovative therapeutics increasingly require highly specialized delivery systems. In the recent publication “Dual-sensitive gelatin-coated chitosan microparticles (GL-ChMPs) for targeted lung delivery”, researchers present a promising strategy: chitosan-based microparticles coated with gelatin that can transport drugs directly to the lungs – smart, sensitive, and efficient.
Oral infections such as periodontitis, peri implantitis, or wound healing complications after tooth extractions remain major challenges in dentistry. Commonly used antibiotics or systemic therapies often reach their limits: drug concentrations at the infection site are frequently insufficient, while side effects and resistance development pose additional risks. For this reason, locally active, bioactive materials are gaining increasing attention in research.
The treatment of complex bone defects, particularly in the cranio-maxillofacial region, remains a major clinical challenge. Autologous grafts are considered the gold standard, but they are associated with limitations such as resorption, insufficient fit, and infection risks.
Dopamine is one of the most important neurotransmitters in the human brain. Its imbalance is associated with neurological disorders such as Parkinson’s disease, schizophrenia, or Huntington’s disease.
Radiotherapy remains one of the main pillars of modern cancer treatment. However, despite advances in precision targeting, damage to surrounding healthy tissue continues to pose a significant clinical problem - especially in thoracic malignancies. In such cases, the lungs represent a particularly radiosensitive organ.
