Talk:Chitin nanofibril

comment

This article is strongly biased and confusing. The structure refereed by the author(PierfrancescoMorganti) as "chitin nano-fibrils" is nonexistent and not a "new natural raw material", it is just a term invented by the author to designate the well known chitin micro-fibrils. Chitin microfibrils are structures formed by the aggregation of chitin polymer chains in crustacean shells (http://www.mpie.de/index.php?id=2957) The author, with interest in cosmetic industry (see references) claim as new a structure that have been extracted from decades and used in industry, including cosmetics, as raw chitin and chitosan. The claims about the properties are not demonstrated, and the article provide with wrong information, claiming that this natural structure (well known in physiology) is different from normal chitin.

I recommend the complete deletion of this article or its transformation to the physiological description of chitin nanofibers — Preceding unsigned comment added by 161.116.100.92 (talk • contribs) 21:30, 20 June 2013 (UTC)

I agree about Chitin microfibrils in nature, but Chitin Nanofibrils ,named also wiskers ,are nanocrystals of Chitin obtained by a refinig industrial method from Chitin powder. These nanocrystals /fibers have been controlled and measured by different physicochemical modalities., as reported from many scientific published papers. These Nanofibrils have been used to increase the mechanical resistence of Chitosan and other natural fibres useful to,produce innovative nanocomposites for food packagings . Moreover they may be used to produce block copolymeric nanoparticles entrapping different active ingredients to be embedded into the pharmaceutical and cosmetic emulsions.

This is my reply to prof RAABE
