Chitin in whisker form, which is a uniform rigid rod-like nanocrystal
prepared from chitin powder, is a potential material due to
its high surface area and accessibility at nano-sized dimensions (Nair
& Dufresne, 2003). Our group succeeded in preparing chitosan whiskers
(CSWK) via a simple and effective one-pot deacetylation of chitin
whiskers. The CSWK exhibits excellent active surface and allows
for the effective chemical functionalization
