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.

Theoretical and Experimental Chemistry, Pages 243-251, 56 (2020)

Positively charged (zeta potential 22-31 mV) hydrogel microparticles based on low and high molecular weight chitosan were synthesized. The effect of the crosslinking agent on their physicochemical characteristics was studied. It was established, that among obtained hydrogel particles, the ones ba… read more

QbD based development of resveratrol-loaded mucoadhesive lecithin/chitosan nanoparticles for prolonged ocular drug delivery
Mithun Saha, Diti Rani Saha, Tahamina Ulhosna, Shazid Md Sharker, Md Hasanuzzaman Shohag, Muhammad Saiful Islam, Swapan K. Ray, G.M Sayedur Rahman, Hasan Mahmud Reza
Journal of Drug Delivery Science and Technology, 102480, 63 (2021)

The lower drug retention to the eye's anterior portion is a prime concern in the ocular drug delivery system. To improve the drug retention capacity, we aimed to develop drug–containing nanoparticles using Quality by Design (QbD) approach. The current study describes the development of resveratrol-… read more

Smart thermosensitive copolymer incorporating chitosan–zinc–insulin electrostatic complexes for controlled delivery of insulin: effect of chitosan chain length
Divya Sharma, Sanjay Arora, Jagdish Singh
International Journal of Polymeric Materials and Polymeric Biomaterials, 1054-1068, 69(16) (2020)

This work was designed to optimize the thermosensitive copolymeric depot-based system for delivering insulin at a controlled rate for a prolonged period following a single subcutaneous injection. The intrinsic ability of insulin to form hexamers in the presence of zinc and electrostatic complexes w… read more

pH-Sensitive Chitosan Nanoparticles for Salivary Protein Delivery
Yi Zhu, Lina M. Marin, Yizhi Xiao, Elizabeth R. Gillies, Walter L. Siqueira
Nanomaterials, 1028, 11(4) (2021)

Salivary proteins such as histatins (HTNs) have demonstrated critical biological functions directly related to tooth homeostasis and prevention of dental caries. However, HTNs are susceptible to the high proteolytic activities in the oral environment. Therefore, pH-sensitive chitosan nanoparticles … read more

Prediction of coating thickness for polyelectrolyte multilayers via machine learning

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
