Recently, biopolymer based wound dressing films were studied due to their biocompatibility and biodegradability. In this study, a film was prepared with alginate (Alg) and carboxymethyl cellulose (CMC) by crosslinking with Ce3+ ion to evaluate the antibacterial properties of the film. The film exhibits antibacterial activity against Gram positive (Staphylococcus aureus) and Gram negative (Escherichia coli) bacteria. Physical and chemical characterizations of the film were assessed through FT-IR spectrometry, SEM, swelling, water vapor transmission (WVT), and ultraviolet-visible light transmittance tests. The chemical and physical attributes of the film prove to be potentially advantageous for wound dressings due to its UV-protective, vapor permeable, swellable and antimicrobial properties.

“…

where hv represents the energy of the incident photon, h exhibits the Planck’s constant,

is the optical coefficient, v represents the frequency of the photon, and A represents the transition constant. The direct E g value of the CeO 2 -NRs was found to be 3.4541 eV, which is again indicative of the fact that the engineered NMs are capable of utilizing the UV region effectively [ 27 ].…”

In this study, cerium oxide nanorods (CeO2-NRs) were synthesized by using the phytochemicals present in the Dalbergia sissoo extract. The physiochemical characteristics of the as-prepared CeO2-NRs were investigated by using ultraviolet-visible spectroscopy (UV-VIS), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction analysis (XRD). The SEM and UV-VIS analyses revealed that the acquired nanomaterials possessed a rod-like morphology while the XRD results further confirmed that the synthesized NRs exhibited a cubic crystal lattice system. The antioxidant capacity of the synthesized CeO2-NRs was investigated by using several in vitro biochemical assays. It was observed that the synthesized NRs exhibited better antioxidant potential in comparison to the industrial antioxidant of the butylated hydroxyanisole (BHA) in 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. The biochemical assays, including lipid peroxidation (LPO), total antioxidant capacity (TAC), and catalase activity (CAT), were also performed in the human lymphocytes incubated with the CeO2-NRs to investigate the impact of the NRs on these oxidative biomarkers. Enhanced reductive capabilities were observed in all the assays, revealing that the NRs possess excellent antioxidant properties. Moreover, the cytotoxic potential of the CeO2-NRs was also investigated with the MTT assay. The CeO2-NRs were found to effectively kill off the cancerous cells (MCF-7 human breast cancer cell line), further indicating that the synthesized NRs exhibit anticancer potential as well. One of the major applications studied for the prepared CeO2-NRs was performing the statistical optimization of the photocatalytic degradation reaction of the methyl orange (MO) dye. The reaction was optimized by using the technique of response surface methodology (RSM). This advanced approach facilitates the development of the predictive model on the basis of central composite design (CCD) for this degradation reaction. The maximum degradation of 99.31% was achieved at the experimental optimized conditions, which corresponded rather well with the predicted percentage degradation values of 99.58%. These results indicate that the developed predictive model can effectively explain the performed experimental reaction. To conclude, the CeO2-NRs exhibited excellent results for multiple applications.

“…The possible mechanisms that cause this reaction was due to the scavenge role of n-CeO 2 against ROS. Also, the green synthesized n-CeO 2 (spherical, average size, 17 nm) exhibit a high antimicrobial activity against S.aureus, E.coli, P. aeruginosa, C. albicans, and A. fumigatus in the range of 15-31 mm zone inhibition (Putri et al, 2021).…”

“…The antibacterial activity of n-CeO 2 is related to its photocatalytic characteristics. Specifically, ROS entering bacterial cells and bends with cellular constituents such as the mesosome, cytoplasm, protein, and nucleoid, causing serious damage to the cell components, weakening the cells, and finally leading to cell death (Putri et al, 2021). Thus, this is an interesting research area focusing on the therapeutic use of n-CeO 2 as antioxidants.…”

The widespread usage of nanotechnology in many essential products has raised concerns about the possible release of nanoparticles (NPs) into aquatic habitats. Cerium dioxide (CeO2) has gained the most interest in the worldwide nanotechnology industry of all types of Ce minerals owing to its beneficial uses in a wide range of industry practices such as catalysts, sunscreens, fuel additives, fuel cells, and biomedicine. Besides, it was realized that CeO2 nanoparticles (n-CeO2) have multi-enzyme synthesized properties that create various biological impacts, such as effectively antioxidant towards almost all irritant intracellular reactive oxygen species. Lately, it was discovered that a large amount of n-CeO2 from untreated industrial waste could be released into the aquatic environment and affect all living organisms. In addition, the physical/chemical characteristics, fate, and bioavailability of nanomaterials in the aquatic environment were discovered to be related to the synthesis technique. Thus, there are intended needs in identifying the optimal technique of synthesized CeO2 nanoparticles in order to assess their beneficial use or their potential ecotoxicological impacts on aquatic organisms and humans. Therefore, this review sheds light on the possible threats of n-CeO2 to aquatic creatures as well as its synthesized techniques. Also, it discusses the possible mechanism of n-CeO2 toxicity as well as their potential benefits in the aquaculture industry.
