“…Wach's group has applied electron beam irradiation to prepare gels from chitosan. They synthesized a series of novel gels of carboxymethylated chitosan derivatives by electron beam for biomedical applications and their characteristics are being studied in detail (Mozalewska et al 2017;Czechowska-Biskup et al 2016). Solutions of chitosan and carboxymethyl-chitosan were subjected to irradiation by electron beam in the presence of poly(ethylene glycol) diacrylate in order to produce carboxymethyl-chitosan-and chitosan-based hydrogels.…”

Synthetic dyes are an important class of recalcitrant organic compounds that are often found in the environment as a result of their wide industrial use. There are estimated to be more than 100,000 commercially available dyes. These substances are common contaminants, and many of them are known to be toxic or carcinogenic. Colored effluents from the industry is perceived by the public as an indication of the presence of a dangerous pollution. Even at very low concentrations, dyes are highly visible-an esthetic pollution-and modify the aquatic life and food chain, as a chemical contamination. Dye contamination of water is a major problem worldwide, and the treatment of wastewaters before their discharge into the environment has become a priority. Dyes are difficult to treat due to their complex aromatic structure and synthetic origin. In general, a combination of different physical, chemical and biological processes is often used to obtain the targeted water quality. Nonetheless, there is a need to develop new removal strategies and decolorization methods that are more effective, acceptable for industrial use and ecofriendly. Currently, there is increasing interest in the application of biological materials as effective adsorbents for dye removal. Among all the materials proposed, cross-linked chitosan-based hydrogels are the most popular biosorbents. These polymeric matrices are the object of numerous fundamental studies. In this review, after a brief description of the use of chitosan in wastewater treatment and the basic principles of chitosan-based hydrogels and biosorption, we focus on some of the work published over the past 5 years. Overall, these polymeric materials have demonstrated outstanding removal capabilities for some dyes. They might be promising biosorbents for environmental purposes.

“…Polymerization is often initiated by a free‐radical catalyst (e.g., azo‐bis (isobutyronitile)) combined with ammonium peroxodisulphate or through various radiation methods (e.g., gamma radiation, ultraviolet radiation, and electron beam radiation) (Lian & Ye, ). Gamma radiation cross‐linking (Mozalewska et al, ) was employed to obtain sterile hydrogel materials for wound treatment. Hydrogel dressings are available as films with or without adhesive borders or amorphous gels; they are nontoxic and nonreactive with biological tissue.…”

Chronic venous insufficiency (CVI) is a common disorder worldwide. Related pathophysiological mechanisms reportedly involve venous pooling and reduced venous return, leading to heaviness, aching, itchiness, tiredness, varicosities, pigmentation, and even lower limb ulceration. Approaches adopted to manage CVI at various stages of clinical‐etiology‐anatomy‐pathophysiology include compression therapy, pharmacological treatment, ultrasound treatment, surgery, electrical or wireless microcurrent stimulation, and pulsed electromagnetic treatment. Among these, polymer‐based therapeutic compression materials and wound dressings play increasingly key roles in treating all stages of CVI because of their unique physical, mechanical, chemical, and biological functions. However, the characteristics, working mechanisms, and effectiveness of these CVI treatment materials are not comprehensively understood. The present systematic review examines the structures, properties, types, and applications of various polymer‐based compression materials and wound dressings used in prophylaxis and treatment of CVI. Existing problems, limitations, and future trends of CVI treatment materials are also discussed. This review could contribute to the design and application of new functional polymer materials and dressings to enhance the efficiency of CVI treatments, thereby facilitating patients' self‐care ability and long‐term health improvement.
