In the summer months July and August, 222 publications about chitosan and chitosan derivatives have been released. Most of these reports examined chitosan-based pharmaceutical preparations and nanoparticles and analysed the effectiveness in animal and human studies. The leading countries in chitosan research are: China (70 articles), India (23) and Taiwan (16).

231 articles about chitosan and chitosan derivatives have been published in May and June 2013. The main topics focused on animal and human studies and on chitosan-based nanoparticles and pharmaceutical preparations. Moreover, the physico-chemical properties and pH sensitivity of various chitosan derivatives were intensively studied. Among the top nations of chitosan research are again: China (76 articles), USA (30) and India (14).

At the end of the year 2014 numerous articles about chitosan and chitosan derivatives were published.  All in all 312 reports were released in November and December by leading scientists from China (89 articles), USA (35) India (28) and South Korea (21).

In September and October, 276 chitosan-related articles have been released. The main topics addressed chitosan in evaluation studies, pharmaceutical preparations, nanoparticles and tissue engineering. The highest number of publications was performed by the leading nations China (73 articles), USA (28) and India (22). German scientists published 8 articles, placing them in the top-ten list.
