As the population ages, the number of Alzheimer's cases could triple by 2050. To enable early diagnosis, sensitive and easy-to-use diagnostic platforms are needed. Therefore, in the presented study, an electrochemical immunosensor was fabricated using chitosan and gold nanoparticles functionalized carbon nanotubes.

At the end of the year, we briefly reflect on which topics it was all about in the chitosan world in 2017. In addition, we present an article about Alzheimer´s disease and the neuroprotective effect of chitosan, chitosanoligosaccharides, and their derivatives.

• Overview about 2017
• Directly to treatment of Alzheimer´s disease with chitosan?
