Special Issue Information

Dear Colleagues,

Chitosan is widely used as a biocompatible biomaterial for various purposes. Due to its strong positive charge, chitosan is readily attracted to the surface of nanoparticles, microbeads, fibres, lipid-based particles, etc., in the common process of chitosan coating. Chitosan coating usually increases the stability of and imparts other biological functions on the coated system.  Moreover, chitosan is easily modified, producing several derivatives with novel functions which further promote the applications of chitosan coatings.

Recent scientific and technological advances in many areas require innovative materials with multifunctional features. Coatings using chitosan and its derivatives promise feasible solutions to many such problems. However, there is still much work to be done in developing new chitosan coating systems to meet specific requirements and applications. In addition, it is imperative to understand the mechanisms of how chitosan coatings impact the coated materials. Herein, we are pleased to invite you to a Special Issue of “Coatings using Chitosan and its Derivatives” published in Polymers

This Special Issue aims to highlight recent advances in coatings using chitosan and its derivatives for specific applications. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. Novel development of chitosan derivatives for coating applications;
  2. Chitosan-based coating of nano/micro-delivery systems for agriculture, food, environment, pharmaceutical applications, etc.;
  3. Impact of chitosan-based coatings on the physicochemical properties and their underlying mechanisms;
  4. Safety and toxicology evaluation of chitosan-based coatings.

We look forward to receiving your contributions.

Although metallic nanocatalysts such as palladium nanoparticles (Pd NPs) are known to possess higher catalytic activity due to their large surface-to-volume ratio, however, in nanosize greatly reducing their activity due to aggregation. To overcome this challenge, superparamagnetic chitosan-coated manganese ferrite was successfully prepared and used as a support for the immobilization of palladium nanoparticles to overcome the above-mentioned challenge. The Pd-Chit@MnFe2O4 catalyst exhibited high catalytic activity in 4-nitrophenol and 4-nitroaniline reductions, with respective turnover frequencies of 357.1 min−1 and 571.4 min−1, respectively. The catalyst can also be recovered easily by magnetic separation after each reaction. Additionally, the Pd-Chit@MnFe2O4 catalyst performed well in the reductive deprotection of allyl carbamate. Coating the catalyst with chitosan reduced the Pd leaching and its cytotoxicity. Therefore, the catalytic activity of Pd-Chit@MnFe2O4 was proven to be unrestricted in biology conditions. Full article
