Special Issue Information

Dear Colleagues,

Chitosan is a versatile biopolymer, with applications in drug delivery systems, vaccine formulations, wound healing, tissue regeneration, cosmetics, dentistry, food packing, agriculture, among others. The basic properties of chitosan, which make it an optimal material for use, are as follows: biocompatibility, biodegradability, mucoadhesion, and enhancement of permeability. It also has its own actions, such as antibacterial, antifungal, hemostatic, and antioxidant, which provide it with an advantage for use in various fields. Recent research has shown that chitosan also has immunostimulatory, anti-tumor, and anti-inflammatory actions.

Aside from its numerous actions and effects, chitosan has amino and hydroxyl functional groups in its structure, which lead to chitosan derivatives with improved physico-chemical properties and effects being obtained, and to the establishment of interactions with a variety of molecules used to develop biomaterials.

Through the Special Issue “The Chitosan Biomaterials: Advances and Challenges—2nd Edition”, we aim to gather original research and review articles that include the development, preparation, actions and evaluation of various biomaterials based on chitosan and its derivatives, as well as their applications.

In recent years, there has been a challenging interest in developing low-cost biopolymeric materials for wastewater treatment. In the present work, new adsorbents, based on different types of chitosan (commercial, commercial chitin-derived chitosan and chitosan synthesized from shrimp shell waste) and inorganic–organic composites have been evaluated for copper ions removal. The efficacy of the synthesis of chitosan-based composite beads has been determined by studying various characteristics using several techniques, including FTIR spectroscopy, X-ray diffraction, porosimetry (N2 adsorption), and scanning electron microscopy (SEM). Adsorption kinetics was performed using different adsorption models to determine the adsorption behavior of the materials in the aqueous media. For all composite beads, regardless of the type of chitosan used, good capacity to remove copper ions from simulated waters was observed (up to 17 mg/g), which proves that the new materials hold potential for heavy metal retention. However, the adsorption efficiency was influenced by the type of chitosan used. Thus, for the series where commercial chitosan (CC) was used, the removal efficiency was approximately 29%; for the series with chitosan obtained from commercial chitin (SC), the removal efficiency was approximately 34%; for the series with chitosan enriched with CaCO3 (SH), the removal efficiency was approximately 52%.

The coffee industry faces coffee leaf rust caused by Hemileia vastratix, which is considered the most devastating disease of the crop, as it reduces the photosynthetic rate and limits productivity. The use of plant resistance inducers, such as chitosan, is an alternative for the control of the disease by inducing the synthesis of phytoalexins, as well as the activation of resistance genes. Previously, the effect of chitosan from different sources and physicochemical properties was studied; however, its mechanisms of action have not been fully elucidated. In this work, the ability of food-grade high-density chitosan (0.01% and 0.05%) to control the infection caused by the pathogen was evaluated. Subsequently, the effect of high-density chitosan (0.05%) on the induction of pathogenesis-related gene expression (GLUC, POX, PAL, NPR1, and CAT), the enzymatic activity of pathogenesis-related proteins (GLUC, POX, SOD, PPO, and APX), and phytoalexin production were evaluated. The results showed that 0.05% chitosan increased the activity and gene expression of ß-1,3 glucanases and induced a differentiated response in enzymes related to the antioxidant system of plants. In addition, a correlation was observed between the activities of polyphenol oxidase and the production of phytoalexin, which allowed an effective defense response in coffee plants. Full article
