Orthopedic infections can be treated with antibiotic-loaded bone cements. However, due to the growing number of resistances, new formulations are needed to e.g. improve the drug release. For this reason, dual-antibiotic bone cement containing chitosan and chitosan oligosaccharide was prepared in the presented study.

Just like humans, plants have an immune system that they use to fend off pathogens and pests. Chitosan oligosaccharides have the ability to improve plant resistance to pests and diseases by activating the plant's immune system. The effectiveness depends on the structure of the chitosan oligomers, as researchers from Münster found in a study.
