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.
