“…Such antimicrobial polymers can be applied as packaging materials, wound-dressing materials, edible films and coatings and wrapping materials, as well as in tissue engineering and drug delivery. The antimicrobial activity of chitosan, its derivatives and composites against Gram-positive and Gram-negative bacteria has been demonstrated in many studies [ 79 , 80 , 81 , 82 ]. It was found that the outer barrier present in Gram-negative bacteria makes these species very susceptible to chitosan [ 83 , 84 , 85 ].…”

Materials based on natural high molecular compounds are particularly interesting for biomedical applications. It is known that the cross-linking agent used for preparation of biomacromolecule-based materials is as important as used biopolymer. Therefore, natural cross-linkers containing reactive carbonyl groups are of great interest especially for modifying properties of natural polysaccharides. One of the most popular cross-linking agents is glutaraldehyde. Nevertheless, the unreacted particles can be released from the cross-linked material and cause cytotoxic effects. This can be eliminated when using a cross-linker based e.g., on polysaccharides. This article describes quick and efficient synthesis of dialdehyde chitosan (DACS) and its application for the preparation of chitosan films. Materials obtained with different amount of DACS were fully characterized in terms of structure and surface morphology. Thermal and mechanical properties as well as hydrophilic character were also examined. The results obtained were compared with the materials obtained by cross-linking chitosan with low molecular weight glutaraldehyde and high molecular weight cross-linking agent based on polysaccharide–dialdehyde starch. Toxicity of all obtained materials was tested using the Microtox® test. It has been shown that due to better mechanical, thermal and surface properties as well as lower toxicity, dialdehyde chitosan is a very promising crosslinking agent.

“…The positive charged chitosan can interact with the negative charged cell wall components to change the permeability of cells, or combine with proteins and nucleic acids to interfere with the normal physiological function of bacterial or fungal cells [85]. At present, chitosan has been regarded as a promising coating to produce antibacterial paper [86,87], but the antibacterial effect of chitosan is not stable, which is only active under certain pH conditions. The antibacterial effect of chitosan can be effectively improved by the addition of silver nanoparticles [88], metal oxide, and other antibacterial substances.…”

As one of the most abundant natural polymers in nature, polysaccharides have the potential to replace petroleum-based polymers that are difficult to degrade in paper coatings. Polysaccharide molecules have a large number of hydroxyl groups that can bind strongly with paper fibers through hydrogen bonds. Chemical modification can also effectively improve the mechanical, barrier, and hydrophobic properties of polysaccharide-based coating layers and thus can further improve the related properties of coated paper. Polysaccharides can also give paper additional functional properties by dispersing and adhering functional fillers, e.g., conductive particles, catalytic particles or antimicrobial chemicals, onto paper surface. Based on these, this paper reviews the application of natural polysaccharides, such as cellulose, hemicellulose, starch, chitosan, and sodium alginate, and their derivatives in paper coatings. This paper analyzes the improvements and influences of chemical structures and properties of polysaccharides on the mechanical, barrier, and hydrophobic properties of coated paper. This paper also summarizes the researches where polysaccharides are used as the adhesives to adhere inorganic or functional fillers onto paper surface to endow paper with great surface properties or special functions such as conductivity, catalytic, antibiotic, and fluorescence.

“…Nowadays, natural polymers are of significant importance due to their unique properties and possibility of production from renewable sources. Chitosan (CS) is one of the most promising polysaccharide biopolymers with high practical potential due to its non-toxic nature, biocompatibility, antimicrobial activity, film-forming properties, relative chemical, and mechanical stability [ 1 , 2 ]. These properties make CS coatings useful for biomedical, packaging, pharmaceutical, and water-treatment applications [ 2 , 3 , 4 , 5 , 6 ].…”

“…Numerous studies have investigated the antibacterial properties of CS [ 1 , 2 , 7 , 8 , 9 ]. The exact mechanism of the antibacterial activity of CS is not yet fully understood, but it is presumably connected to its polycationic structure in acidic aqueous solutions (pH < 6.3), that can interact with the negatively charged cell walls of bacteria, causing their disruption [ 10 ].…”

Anodic Electrodeposition of Chitosan–AgNP Composites Using In Situ Coordination with Copper Ions

et al. 2021

View full text Add to dashboard Cite

Chitosan is an attractive material for biomedical applications. A novel approach for the anodic electrodeposition of chitosan–AgNP composites using in situ coordination with copper ions is proposed in this work. The surface and cross-section morphology of the obtained coating with varying concentrations of AgNPs were evaluated by SEM, and surface functional groups were analyzed with FT-IR spectroscopy. The mechanism of the formation of the coating based on the chelation of Cu(II) ions with chitosan was discussed. The antibacterial activity of the coatings towards Staphylococcus epidermidis ATCC 35984/RP62A bacteria was analyzed using the live–dead approach. The presented results indicate that the obtained chitosan–AgNP-based films possess some limited anti-biofilm-forming properties and exhibit moderate antibacterial efficiency at high AgNP loads.
