“…MIL-125-NH 2 was integrated into bacteria cellulose@chitosan, and the obtained composite was used as air filters. The advantage of produced filter was highly porous structure, superior filtration properties with high removal efficiencies under low pressure [ 16 ]. MIL-125-NH 2 was used for simultaneously monitor of methyl 1-naphthalene acetate, parathion-methyl, fenitrothion, bromophos and phenthoate residues in pomelo [ 17 ].…”

Microbial resistance is the first morbidity and mortality cause for patients as usually a secondary infection. Additionally, the MOF is a promising material that shows a nice activity in this field. However, these materials need a good formulation to enhance biocompatibility and sustainability. Cellulose and its derivatives are well as filers for this gap. In this presented work, a novel green active system based on carboxymethyl cellulose and Ti-MOF (MIL-125-NH2@CMC) modified with thiophene (Thio@MIL-125-NH2@CMC) was prepared by a post-synthetic modification (PSM) route based. FTIR, SEM and PXRD were utilized to characterize nanocomposites. In addition, transmission electron microscopy (TEM) was used to corroborate the nanocomposites' particle size and diffraction pattern as well as the DLS affirmed the size as 50 and 35 nm for MIL-125-NH2@CMC and Thio@MIL-125-NH2@CMC, respectively. The formulation of the nanocomposites was validated by physicochemical characterization techniques, while morphological analysis confirmed the nanoform of the prepared composites. The antimicrobial, antiviral and antitumor properties of MIL-125-NH2@CMC and Thio@MIL-125-NH2@CMC were assessed. Antimicrobial testing revealed that Thio@MIL-125-NH2@CMC possesses greater antimicrobial activity than MIL-125-NH2@CMC. Additionally, Thio@MIL-125-NH2@CMC demonstrated promising antifungal activity against C. albicans and A. niger where MICs were 31.25 and 0.97 µg/mL, respectively. Also, Thio@MIL-125-NH2@CMC exhibited antibacterial activity against E. coli and S. aureus where MICs were 1000 and 250 µg/mL, respectively. In addition, the results demonstrated that Thio@MIL-125-NH2@CMC displayed promising antiviral activity against both HSV1 and COX B4, with antiviral activities of 68.89% and 39.60%, respectively. Furthermore, Thio@MIL-125-NH2@CMC exhibited potential anticancer activity against MCF7 and PC3 cancerous cell lines, where IC50 was 93.16 and 88.45%, respectively. In conclusion, carboxymethyl cellulose/sulfur-functionalized Ti-based MOF composite was successfully synthesized which had antimicrobial, antiviral and anticancer activities.

“…Since cellulose and chitosan are natural polymers with similar chemical structures, cellulose particles such as nano-fibrillated cellulose (NFC) and cellulose nanocrystal (CNC) were incorporated into the chitosan easily. In this sense, cellulose nanoparticle-embedded chitosan composite can show enhanced physical properties such as mechanical and electrical properties [ 60 , 61 ]. This study embedded CNC into chitosan and composite foam preparation using freeze-drying.…”

In this study, we fabricated a cellulose nanocrystal (CNC)-embedded aerogel-like chitosan foam and carbonized the 3D foam for electrical energy harvesting. The nanocrystal-supported cellulose foam can demonstrate a high surface area and porosity, homogeneous size ranging from various microscales, and a high quality of absorbing external additives. In order to prepare CNC, microcrystalline cellulose (MCC) was chemically treated with sulfuric acid. The CNC incorporates into chitosan, enhancing mechanical properties, crystallization, and generation of the aerogel-like porous structure. The weight percentage of the CNC was 2 wt% in the chitosan composite. The CNC/chitosan foam is produced using the freeze-drying method, and the CNC-embedded CNC/chitosan foam has been carbonized. We found that the degree of crystallization of carbon structure increased, including the CNCs. Both CNC and chitosan are degradable materials when CNC includes chitosan, which can form a high surface area with some typical surface-related morphology. The electrical cyclic voltammetric result shows that the vertical composite specimen had superior electrochemical properties compared to the horizontal composite specimen. In addition, the BET measurement indicated that the CNC/chitosan foam possessed a high porosity, especially mesopores with layer structures. At the same time, the carbonized CNC led to a significant increase in the portion of micropore.
