In recent decades, there have been major advances in regenerative medicine, such as the treatment of severe nerve injuries. Implants used as scaffolds for nerve cell regeneration are often made of biodegradable polymers, such as chitosan. Below, we present a study that investigated the degradation and stability of tubular chitosan-based implants.

Chitin and Chitosan offer beneficial properties for wound dressing materials, like biocompatibility, biodegradability and haemostatic effects. The biopolymer source influences the properties, processing and associated impurities of the chitin. In this article, we want to present a review, which investigated the differences between crustaceans and fungi derived chitin and chitosan regarding wound healing.

In the current corona pandemic, the protection of medical personnel who have contact with Covid-19 infected patients is important, also to ensure stability of the health care services. The personal protective equipment of hospital staff includes particle filtering respiratory masks. From early 2021, a clinical study will be conducted to investigate the protective effect of a new type of respirator with a filter element containing chitosan nanoparticles in Brazil. More about this study and other current clinical studies with chitosan in this article.

The dry eye disease (keratoconjunctivitis sicca) is a widespread disease that leads to an unstable tear film, ocular discomfort and visual disturbances. As the tear film fails to cover the entire conjunctiva and cornea, chronic inflammation of the ocular surface occurs. Here we present two studies where the use of chitosan-based eye drops improved the treatment of the disease.
