Wearable electrodes, which are used to measure a variety of bodily functions, generate electronic waste and, in the case of implants, require extensive removal. The presented study introduces a fully decomposable material mixture with chitosan that can withstand exercise and sweat even under high physical stress.
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.
Artificial nerve conduits are used for peripheral nerve damage, but still have some disadvantages compared to autologous cells, such as lack of neurotrophic factors. In the presented study, a nerve conduit made of chitosan, collagen and Schwann cells is used to repair damage to the sciatic nerve of mice, thus providing a simpler alternative to the complex autologous nerve transplantation.
3D bioprinting can improve the treatment of wounds by producing multifunctional, personalized wound dressings. In the study presented here, hydrogel wound dressings based on galantine, sodium alginate, dopamine and quaternized chitosan with effective antioxidant, antibacterial and biocompatible properties will be fabricated via using this technology.
Chitosan bioglass networks can be used as biomaterials in medicine, for example, as bone implants. Their physiochemical and mechanical properties can be improved by crosslinkers and various stabilization methods. In the presented study, six of them were compared with each other.
The preparation of chitosan-based nanoparticles by ionotrophic gelation often leads to high batch-to-batch variability as well as in low reproducibility. A possible solution to this could be controlled mixing on a microfluidic scale. In the study presented here, chitosan tripolyphosphate nanoparticles with siRNA, mRNA and β-galactosidase as cargo will be prepared using microfluidics.
