Preparation of Chitin Nanofibers from Squid Pen β-Chitin by Simple Mechanical Treatment under Acid Conditions
Abstract
A procedure for preparing individualized chitin nanofibers 3-4 nm in cross-sectional width and at least a few microns in length was developed. The key factors to prepare the chitin nanofibers with such high aspect ratios are as follows: (1) squid pen beta-chitin is used as the starting material and (2) ultrasonication of the beta-chitin in water at pH 3-4 and 0.1-0.3% consistency for a few minutes. Transparent and highly viscous dispersions of squid pen beta-chitin nanofibers in water can be obtained by this method. No N-deacetylation occurs on the chitin molecules during the nanofiber conversion procedure. Moreover, the original crystal structure of beta-chitin is maintained, although crystallinity index decreases from 0.51 to 0.37 as a result of the nanofiber conversion. Cationization of the C2 amino groups present on the crystallite surfaces of the squid pen beta-chitin under acid conditions is necessary for preparing the nanofibers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
