Herein, we present the first direct alkaline periodate oxidation of chitin, which demonstrates at the same time a novel approach for the preparation of chitin nanocrystals (ChNCs). This oxidation is based on an unprecedented selective reaction of non-ordered domains of chitin by the dimeric orthoperiodate ions (H2I2O104−) as the major species in alkaline surroundings. Nearly 50 wt% of non-ordered regions are dissolved after sequential accelerated partial deacetylation, periodate oxidation and β-alkoxy fragmentation, which allows the isolation of up to 50 wt% of uniform anisotropic zwitterionic ChNCs.","lang":"eng"}],"volume":23,"author":[{"first_name":"Peiwen","full_name":"Liu, Peiwen","last_name":"Liu"},{"first_name":"Huan","last_name":"Liu","full_name":"Liu, Huan"},{"full_name":"Schäfer, Timmy","last_name":"Schäfer","first_name":"Timmy"},{"id":"118165","full_name":"Gutmann, Torsten","last_name":"Gutmann","first_name":"Torsten"},{"first_name":"Holger","full_name":"Gibhardt, Holger","last_name":"Gibhardt"},{"last_name":"Qi","full_name":"Qi, Houjuan","first_name":"Houjuan"},{"full_name":"Tian, Lin","last_name":"Tian","first_name":"Lin"},{"first_name":"Xizhou Cecily","last_name":"Zhang","full_name":"Zhang, Xizhou Cecily"},{"first_name":"Gerd","full_name":"Buntkowsky, Gerd","last_name":"Buntkowsky"},{"last_name":"Zhang","full_name":"Zhang, Kai","first_name":"Kai"}],"date_created":"2026-02-07T16:01:08Z","publisher":"The Royal Society of Chemistry","date_updated":"2026-02-17T16:15:12Z","doi":"10.1039/D0GC04054A","title":"Unexpected selective alkaline periodate oxidation of chitin for the isolation of chitin nanocrystals","issue":"2","page":"745–751","intvolume":"        23","citation":{"apa":"Liu, P., Liu, H., Schäfer, T., Gutmann, T., Gibhardt, H., Qi, H., Tian, L., Zhang, X.
