Chitosan is no longer just an interesting biopolymer for the food or wound healing sectors. It is gaining attention in many other fields as well – particularly due to its radical scavenging, hematopoietic, and cytoprotective properties. One of the most promising areas of application: radioprotection, i.e., the protection of tissue from damage caused by ionizing radiation.
Nanocomposites with antioxidant properties are gaining increasing importance in biomedical and particularly dental research. These materials combine conventional substances with nano-particles, aiming to enhance mechanical, chemical, or biological performance. [1]
The development of safe and effective vaccines is a major challenge. In addition to generating an adequate immune response, vaccines must also remain stable over time – both inside and outside the body. In their review article, Masimov and Wasan present various applications of chitosan and chitosan derivatives as adjuvants in the development of particulate and non-particulate vaccines.
The antioxidant, bacteriostatic and antinflammatory properties of chitosan ensure that it is highly suitable for regenerative medicine applications such as wound dressings. In the presented study, a chitosan derivatized via a Schiff base is introduced to further improve these properties.
Chitosan is already being used in many ways in the pharmaceutical, medical and food industries. A less explored field of application is forensics, for example to make fingerprints visible. In the following article we would like to present a study in which the unique properties of chitosan coupled with lysine are used as a powder to visualize latent fingerprints on glass and rubber surfaces.
