Chitin nanowhiskers
WebSep 23, 2024 · Chitin nanowhiskers are on a similar scale to the chitin nanofibers at the fundamental level of crustacean shells; as such, research has been devoted to developing biomimetic materials that emulate properties found in nature, including iridescence seen in the shells of beetles and mantis shrimps . WebJul 27, 2024 · Normally the residual protein content in the chitin produced from conventional commercial sources is around 1%. This yields a partially deacetylated chitin. The obtained chitin flakes or powder can be further deacetylated to chitosan or used for the isolation of nanochitin: chitin nanowhiskers (or nanocrystals) and chitin nanofibers.
