Green synthesis of multifunctional ZnO/chitosan nanocomposite film using wild Mentha pulegium extract for packaging applications

Mechanical properties, sustained release, and oxygen scavenging properties of nanocomposite films loaded with bimetallic nanoparticles (Fe2O3/TiO2) in extra virgin olive oil

“…Also, due to their tiny size and high surface‐to‐volume ratio, nanoparticles spread well in the polymer matrix and are placed in the interfacial region. By placing nanoparticles in the interfacial areas and forming interactions, nanoparticles will cause efficient stress transfer across the nanocomposites (Alamdari et al., 2023; Alamdari et al., 2022; Crosby & Lee, 2007). The cross‐linking formed due to the presence of NH‐Ti 0.01 Fe 0.022 O 0.09 and Na‐Ti 0.01 Fe 0.048 O 0.08 nanoparticles increases the resistance of the films against the applied stresses.…”

“…Modeling of the release behavior of bimetallic nanocomposites from the structure of PLA-based nanocomposite films in EVOO was performed according to the method proposed by Heydari-Majd et al (2019). For this purpose, during 90 days at ambient temperature, the release of NH-Ti 0.01 Fe 0.022 O 0.09 and Na-Ti 0.01 Fe 0.048 O 0.08 nanoparticles from the structure of PLA-based nanocomposite films in EVOO using an atomic absorption spectrometer (Perkin-Elmer, Zeeman PC 5100 model) was determined (Alamdari et al, 2022). Films with dimensions of 3 × 3 cm 2 were immersed in 200 mL of olive oil, and sampling was done during days 0, 15, 30, 45, 60, 75, and 90 (Heydari-Majd, Ghanbarzadeh, et al, 2019).…”

Progress of Research on Antioxidants and Carriers for Skin Wound Repair

“…The nanocomposite films prepared on the basis of chitosan and gelatin show good co-persistence and absorption in wound dressings; they not only have good antioxidant capacity but also the capacity to promote wound recovery [55]. A biodegradable hybrid film composed of green synthesized zinc oxide nanoparticles (ZnONPs) and a chitosan (CS) matrix exhibited remarkable antibacterial and antioxidant properties with strong visible emission and UV-blocking activities in the 480 nm region [56]. Nano-enzyme is a kind of nanomaterial with enzyme-mimicking activity, which has relatively high physical and chemical stability in a harsh environment, higher durability and lower cost compared to natural enzymes [57].…”

Antibacterial and Photodegradation of Organic Dyes Using Lamiaceae-Mediated ZnO Nanoparticles: A Review

“…The ZnO NPs were obtained via the thermal decomposition of the complex [136]. Alamdari et al [140] attributed the capping and stabilisation of M. pulegium-mediated ZnO NPs to the functional groups -C-C-, -C-O-, -C=C-, and -C=O from phytochemicals such as alkaloids, flavonoids, phenols, and anthracenes, which were observed from the Fourier transform infrared spectroscopy (FTIR) spectrum of M. pulegium-mediated ZnO NPs. Additionally, the authors also reported the disappearance of -OH functional groups observed from the FTIR spectrum of M. pulegium leaf extracts and attributed this to the -OH groups taking part in the reduction during the synthesis of ZnO NPs.…”
