Production and characterization of a nanocomposite of highly crystalline nanowhiskers from biologically extracted chitin in enzymatic poly(ε-caprolactone)

The role of nanochitin in biologically-active matrices for tissue engineering-where do we stand?

“…Although the incorporation of nanochitin has led to successful applications in TE with a multitude of synthetic polymers, [61][62][63][64][65][66][67][68] herein the discussion throughout the next section (Section 3) is focused only on natural polymers as biologically-active matrices. Table 1 summarizes the TE applications for biomaterials prepared using chitin nanocrystals or nanofibers into biologically-active matrices in the last years.…”

Chitosan Natural Polymer Material for Improving Antibacterial Properties of Textiles

“…In addition, the molecular weight of chitin obtained by fermenting shrimp waste using Lactobacillus brevis with and without further inoculations with Rhizopus oligosporus was higher than commercial biopolymer . Chitin can be obtained by lactic acid fermentation of shrimp waste, which can be converted into chitin whisker by acid hydrolysis at a low temperature (4 °C) by a novel process, which improved the distribution and yield of chitin . Six protease-producing Bacillus species (Bacillus subtilis A26, Bacillus mojavensis A21, Bacillus pumilus A1, Bacillus amyloliquefaciens An6, Bacillus licheniformis NH1, and Bacillus cereus BG1) were used to ferment crab shell waste to extract chitin.…”

Fourier transform infrared spectrum showed that the extracted chitin was α-chitin.…”

Recent Advances in Chitin and Chitosan/Graphene-Based Bio-Nanocomposites for Energetic Applications

“…Owing to its biocompatibility, chitosan has also been deemed a suitable material for wastewater treatment, as well as for medicinal and electrochemical applications [ 19 , 20 ]. As nanotechnology advances, the fabrication of chitosan nanocomposites with organic and inorganic nanofillers has significantly improved the material’s mechanical, chemical and barrier properties [ 21 ]. These remarkable results are squandered as there are no works in the literature that study systematic nanostructures, novel bio-nanocomposite possibilities and their associated fabrication processes, which are needed.…”
