Chitosan is a promising drug delivery system for pulmonary applications and is therefore of particular interest for vaccine development in the Corona Pandemic. The biodegradable and biocompatible polymer's mucoadhesive, permeation-increasing and site-/cell-specific properties are useful in this context. Nanocarriers based on various microencapsulation and micro-nano mixing systems have already been developed. The aerodynamic character is important to enable efficient pulmonary aerosol formation and inhalation. In this article we present research on chitosan as pulmonary particulate anti-infective drug carrier.

Humankind has long dreamed of setting foot on the Red Planet. In order to implement the ambitious plans by 2040 and send a manned mission to Mars, new technologies are needed to meet the technical, financial and health challenges. An essential point is the use of resources on Mars.

Stem cell therapy has received a lot of attention in recent years and has created new ways of treating the various conditions and ailments. The stem cells can differentiate into a wide variety of cell types and can positively influence inflammatory reactions. Clinical applications of stem cells are still limited, among others due to the high concentrations of ROS (reactive oxygen species) in the environment of the inflammation which limits retention of the transplanted stem cells.

Natural polysaccharides such as chitin and chitosan are excellent sources for new materials with exceptional properties. Here we present innovative applications of the biopolymer derived from crustaceans or mushrooms in bulletproof coatings and smart windows.
