Chitosan is a polysaccharide comprised of linked D-glucosamine and N-acetyl-D-glucosamine units. It is produced by the deacetylation of chitin, a naturally occurring polysaccharide. Chitosan is commercially used in agriculture as a biopesticide but has potential applications in the biomedical field due to its antibacterial properties. This product is derived from shrimp shell.

Permeability of Novel Chitosan-g-Poly(Methyl Methacrylate) Amphiphilic Nanoparticles in a Model of Small Intestine In Vitro
Imrit Noi, Inbar Schlachet, Murali Kumarasamy and Alejandro Sosnik
Polymers, 478, 10(5) (2018)

Engineering of drug nanocarriers combining fine-tuned mucoadhesive/mucopenetrating properties is currently being investigated to ensure more efficient mucosal drug delivery. Aiming to improve the transmucosal delivery of hydrophobic drugs, we designed a novel nanogel produced by the self-assembly o… read more

Chitosan ascorbate hydrogel improves water uptake capacity and cell adhesion of electrospun poly(epsilon-caprolactone) membranes
Robin Augustine, Pan Dan, Inbar Schlachet, Didier Rouxel, Patrick Menu, Alejandro Sosnik
International Journal of Pharmaceutics, Pages 420 - 426, 559 (2019)

The most important prerequisites for wound coverage matrices are biocompatibility, adequate porosity, degradability and exudate uptake capacity. A moderate hydrophilicity and exudate uptake capacity can often favour cell adhesion and wound healing potential, however, most of the synthetic polymers … read more

Monodisperse highly ordered chitosan/cellulose nanocomposite foams
Sebastien Andrieux, Lilian Medina, Michael Herbst, Lars A. Berglund, Cosima Stubenrauch
Composites Part A: Applied Science and Manufacturing, 105516, 125 (2019)

In solid foams, most physical properties are determined by the pore size and shape distributions and the organisation of the pores. For this reason, it is important to control the structure of porous materials. We recently tackled this issue with the help of microfluidic-aided foam templating, whic… read more

New bio-based phosphorylated chitosan/alginate protective coatings on aluminium alloy obtained by the LbL technique
Clément Coquery, Federico Carosio, Claire Negrell, Nicolas Caussé, Nadine Pébère, Ghislain David,
Surfaces and Interfaces, 59-66, 16 (2019)

Bio-based coatings were obtained by the layer-by-layer (LbL) technique from a native chitosan (Mw ≈ 30,000 g mol−1) or from two synthesized phosphorylated chitosan of different molecular weights (Mw ≈ 30,000 g mol−1 and Mw ≈ 250,000 g mol−1) combined with alginate and used for corrosion protection … read more

Design and Validation of Liposomal ApoE2 Gene Delivery System to Evade Blood–Brain Barrier for Effective Treatment of Alzheimer’s Disease
Sanjay Arora, Buddhadev Layek, Jagdish Singh
Molecular Pharmaceutics, 714-725, 18(2) (2021)

Targeting gene-based therapeutics to the brain is a strategy actively sought to treat Alzheimer’s disease (AD). Recent findings discovered the role of apolipoprotein E (ApoE) isoforms in the clearance of toxic amyloid beta proteins from the brain. ApoE2 isoform is beneficial for preventing AD devel… read more

Smart thermosensitive copolymer incorporating chitosan–zinc–insulin electrostatic complexes for controlled delivery of insulin: effect of chitosan chain length

Scientific Reports, 18702, 11 (2021)

Layer-by-layer (LbL) deposition method of polyelectrolytes is a versatile way of developing functional nanoscale coatings. Even though the mechanisms of LbL flm development are well-established, currently there are no predictive models that can link flm components with their fnal properties. The cu… read more
