During the last decade green synthesized cerium oxide nanoparticles (CeO 2 NPs) attracted remarkable interest in various fields of science and technology. This review, explores the vast array of biological resources such as plants, microbes, and other biological products being used in synthesis of CeO 2 NPs. It also discusses their biosynthetic mechanism, current understandings, and trends in the green synthesis of CeO 2 NPs. Novel therapies based on green synthesized CeO 2 NPs are illustrated, in particular their antimicrobial potential along with attempts of their mechanistic elucidation. Overall, the main objective of this review is to provide a rational insight of the major accomplishments of CeO 2 NPs as novel therapeutics agents for a wide range of microbial pathogens and combating other diseases.

“…Specific surface area and pore size distribution of the synthesized CeO2 NPs are calculated using nitrogen adsorption-desorption isotherms. Figure 5b shows the nitrogen adsorptiondesorption isotherm at 77 K and the measured Brunauer-Emmett-Teller (BET) specific surface area of CeO2 NPs is 40.96 m 2 /g, which is much higher than commercial CeO2 NPs (8.50 m 2 /g) [25]. Additionally, Barrett-Joyner-Halenda (BJH) pore size distribution curve displays a narrow pore size distribution with a calculated pore diameter of 7.8 nm.…”

Ceria nanoparticles (CeO2 NPs) are generally considered in various functional applications, such as catalysts in fuel cells, sensors, and antioxidant and oxidase-like enzymes in the biological environment. The CeO2 NPs were synthesized using the E. globulus leaf extract-mediated hydrothermal technique. The synthesized NPs were characterized by various analytical instruments including powder X-ray diffractometer (PXRD), scanning electron microscope (SEM), transmission electron microscope (TEM) and dynamic light scattering (DLS) analysis. The XRD results showed an average NPs sizes of 13.7 nm. Cytotoxic study results showed an IC50 value of 45.5 µg/L for A549 and 58.2 µg/L for HCT 116, indicating that CeO2 NPs are more toxic to A549 compared to HCT116 cell lines. The generation of ROS was responsible for its cytotoxic activity against cancer cell lines. Specific surface area (40.96 m2/g) and pore diameter (7.8 nm) were measured using Brunauer–Emmett–Teller (BET) nitrogen adsorption–desorption isotherms. CeO2 NPs with a high surface area were used as photocatalyst in degrading sunset yellow (SY) dye under UV-irradiation and 97.3% of the dye was degraded within 90 min. These results suggest that the synthesized CeO2 NPs could be used as a good photocatalyst as well as a cytotoxic agent against human cancer cell lines.

Burns injuries induce a state of immunodepression that predisposes to a bacterial infectious complication that leads to several comorbid diseases and high mortality rate. Previous studies about anti-infl ammatory, antimicrobial and antioxidant properties of Aloe vera (L.) Burm., Calendula offi cinalis L. and Matricaria recutita L. are acknowledge by antimicrobial effects. Previous studies about anti-infl ammatory, antimicrobial and antioxidant properties of Aloe vera (L.) Burm., Calendula offi cinalis L. and Matricaria recutita L. are knowledge by antimicrobial effects. Bacterial cellulose membrane (nature BCM) is a potential carrier as a drug delivery system in the wound and burn treatment. The present study aimed to evaluate the antibacterial activity of extracts of A. vera, C. offi cinalis, and M. recutita incorporated in BCM against bacterial strains commonly present in wound and burns. The agar-dilution susceptibility testing was used to determine the minimum inhibitory concentration (MIC) for S. aureus, E. coli, and P. aeruginosa. The standardized extracts of A. vera, M. recutita, and C. offi cinalis were, respectively, used at 3.25% of total polysaccharides, 1% of apigenin 7-O-glucoside and 0.084% of total fl avonoids expressed in quercetin. The BCM incorporated with A. vera extract was effi cient to prevent the growth of P. aeruginosa and S. aureus. BCM loaded with C. offi cinalis inhibited the growth of S. aureus. The BCM loaded with A. vera and C. offi cinalis extract showed better antibacterial activities against P. aeruginosa and S. aureus and, consequently, properties to prevent infectious disease in the wound or burn caused by these bacteria.
