“…and the fungal pathogens Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus, and Candida albicans [23]. Such nanocomposites demonstrated minimum bactericidal concentration values of 39.1 and 312.5 µg/ml for E. coli and S. aureus, respectively, and did not exhibit cytotoxicity to L-929 fibroblasts [24]. Chitosan hydrogels, reinforced with silver nanoparticles, revealed ultra-high mechanical and high antibacterial properties against E. coli and S. aureus and were used to accelerate wound healing [25].…”

The surface treatment of titanium implants has been applied mainly to increase surface bioactivity and, more recently, to introduce antibacterial properties. To this end, composite coatings have been investigated, particularly those based on hydroxyapatite. The present research was aimed at the development of another coating type, chitosan–nanosilver, deposited on a Ti13Zr13Nb alloy. The research comprised characterization of the coating’s microstructure and morphology, time-dependent nanosilver dissolution in simulated body fluid, and investigation of the nanomechanical properties of surface coatings composed of chitosan and nanosilver, with or without a surface-active substance, deposited at different voltages for 1 min on a nanotubular TiO2 layer. The microstructure, morphology, topography, and phase composition were examined, and the silver dissolution rate in simulated body fluid, nanoscale mechanical properties, and water contact angle were measured. The voltage value significantly influenced surface roughness. All specimens possessed high biocompatibility. The highest and best adhesion of the coatings was observed in the absence of a surface-active substance. Silver dissolution caused the appearance of silver ions in solution at levels effective against bacteria and below the upper safe limit value.

“…COS exert obvious efficiency for preventing intestinal lipid absorption and improving liver lipid biosynthesis and accumulation [7] while lipid profile is an important risk factor of CHD [8]. Furthermore, COS have excellent biological properties presenting a promising prospect in antibacterial [9] and antioxidant biomaterials [10] with little cytotoxicity. Antioxidant therapy will be an effective way for CHD treatment since long-term hyperglycemia can result in the enhancement of oxidative stress [11].…”

We explored the effects of chitosan oligosaccharides (COS) on coronary heart disease (CHD) patients. The component of COS was measured by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). CHD patients were evenly assigned into the COS group (COG) and the placebo group (CG). The duration of treatment was 6 months and therapeutic results were explored by measuring left ventricular ejection fraction (LVEF) value, Lee scores, quality of life (QOL), blood urea nitrogen, and serum creatinine. The intestinal flora were determined by 16s rDNA sequencing. The circulating antioxidant levels and lipid profiles were compared between two groups. There were 7 different degrees of polymerization (DP4-10) in COS. Lee scores, QOL scores, and LVEF values in the COG group were higher than those in the CG group (P<0.05). COS treatment improved blood urea nitrogen and serum creatinine when compared with controls (P<0.05). Circulating antioxidant levels were higher in the COG group than in the CG group. COS consumption increased the serum levels of SOD and GSH and reduced the levels of ALT and AST (P<0.05). Meanwhile, lipid profiles were improved in the COG group. COS consumption increased the abundance of Faecalibacterium, Alistipes, and Escherichia and decreased the abundance of Bacteroides, Megasphaera, Roseburia, Prevotella, and Bifidobacterium (P<0.05). On the other hand, COS consumption increased the probiotic species Lactobacillus, Lactococcus, and Phascolarctobacterium. The increased species have been reported to be associated with antioxidant properties or lipid improvement. COS had similar effects with chitohexaose on the growth rate of these species. Therefore, COS ameliorate the symptoms of CHD patients by improving antioxidant capacities and lipid profiles via the increase of probiotics in the intestinal flora.

“…In this sense, it was demonstrated that chitosan can act as both a reducing and stabilizing agent in the synthesis of AgNPs [77]. For instance, AgNPs stabilized with chitosan were synthesized at a large scale by a green method using autoclave, in which chitosan functions as a reducing agent as well as a stabilizer [78]. It was shown that, while chitosan only can prevent the growth of S. aureus , AgNPs stabilized with chitosan are also able to inhibit the growth of E. coli bacteria.…”

This article concisely reviews the most recent contributions to the development of sustainable bio-based polymers with antimicrobial properties. This is because some of the main problems that humanity faces, nowadays and in the future, are climate change and bacterial multi-resistance. Therefore, scientists are trying to provide solutions to these problems. In an attempt to organize these antimicrobial sustainable materials, we have classified them into the main families; i.e., polysaccharides, proteins/polypeptides, polyesters, and polyurethanes. The review then summarizes the most recent antimicrobial aspects of these sustainable materials with antimicrobial performance considering their main potential applications in the biomedical field and in the food industry. Furthermore, their use in other fields, such as water purification and coating technology, is also described. Finally, some concluding remarks will point out the promise of this theme.
