“…However, the bands at 1420-1375, 1085-1150, and 838 cm −1 , which are als acteristic of chitosan, may be interposed with those of PVA. In this case, for chitosa bands are attributed to the symmetric deformations of the CH2 and CH3 grou stretching vibrations of the C-O-C groups characteristic of polysaccharides, a amine groups of chitosan, respectively [31][32][33].…”

“…Ch has different molecular weights (5X10 4 -2X10 6 Da) and degree of deacetylation (DD) (40% -98%). Ch is widely used in several fields such as biomedical, food additives, antimicrobial agents, pharmaceutical, wastewater treatment, paper, and textiles because Ch has excellent properties such as antimicrobial, antioxidant, biodegradable, biocompatible, non-toxic, and antiinflammatory properties [147][148][149][150][151][152][153][154][155][156].…”

Designing high-performance adsorbents for wastewater treatment and antibacterial materials for food and biomedical applications and excellent drug carrier to prolong time retention of the therapeutic drug based on biodegradable polymers has gained more interest in recent years. Among these materials, xanthan gum, which is a natural polysaccharide and plays a vital role in various applications such as industry, enhanced oil recovery, water-based paints, pharmaceuticals, and personal care products because it has excellent properties such as biodegradability and non-toxicity. On the other hand, it has many affected limitations, including microbially attack, poor thermal and mechanical stability, and low surface area. So, in this review, we focused on the advanced modifications on xanthan gum and their applications in wastewater treatment, protein delivery, and designing antimicrobial materials.

“…[1][2][3][4] Despite the exciting properties DOI: 10.1002/star.202300258 of biopolymers, such as biocompatibility and environmental sustainability, they do not present antimicrobial properties (except chitosan). [5][6][7] However, the lack of the antimicrobial properties can be solved by incorporating antimicrobial agents. [8][9][10] Antimicrobial agents must fulfill several requirements, such as a broad antimicrobial spectrum at a short contact time, ease of preparation at low cost, high stability at the intended applications and storage, and regeneration after the loss of activity.…”

The microbial resistance to the traditional antibiotics causes serious health problems and increases day by day. Thus, there is a pressing need to discover alternative antimicrobial agents of different nature than that of the conventional antibiotics. For this, novel hydrogel nanocomposite films are prepared by chemical crosslinking grafting of carboxymethyl cellulose with N,N′‐methylene‐bis‐acrylamide (CMC‐g‐MBA), which subsequently followed by loading two different weight ratios of titanium oxide nanoparticles (TiO2NPs), such as 3% (CMC‐g‐MBA/TiO2NPs‐3%) and 5% (CMC‐g‐MBA/TiO2NPs‐5%) wt%. Their chemical structure and surface morphology are confirmed using appropriate analytical techniques. Their antimicrobial activity can be arranged as follows: CMC‐g‐MBA/TiO2NPs‐5% composite > CMC‐g‐MBA/TiO2NPs‐3% composite > CMC‐g‐MBA hydrogel. While, the native CMC has no observable antimicrobial effect. CMC‐g‐MBA/TiO2NPs‐3% composite imparts good barrier properties to the coated tomato fruits, delaying their spoilage and protecting them from the environmental microbes compared to the uncoated ones. CMC‐g‐MBA/TiO2NPs‐5% composite is safe on the normal human cells. Thus, incorporation of both MBA and TiO2NPs into CMC greatly develops its antimicrobial activity and provides a wonderful approach to attain promising materials that can efficiently compete with conventional antibiotics.
