“…et al [20] modified the surface of degummed silk fiber with CeO2 nanoparticles by dip-coating method, and the obtained modified silk showed the excellent UV-shielding ability and antibacterial activity. Gomez et al [21] synthesized Ce 3+ rich CeO2 nanoparticles, which showed good antibacterial activities against both Gram-negative and Gram-positive bacteria due to the existing Ce 3+ on surface and rich oxygen vacancies in CeO2 nanoparticles. Although there are some reports about the antibacterial activity of CeO2, researchers are mainly focused on the influence of CeO2 to the antibacterial activity of Ag/CeO2, [22] ZnO/CeO2 [23,24] and CuO/CeO2 [25] hybrid nanomaterials.…”

CeO2 nanospheres with different diameters were successfully prepared and embedded in one-dimensional chitosan/polyvinyl alcohol (CS/PVA) composite nanofibers by electrospinning technique for further antibacterial evaluation. The obtained composites exhibited different antibacterial activities to Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli). We propose that CeO2-CS/PVA nanofibrous membranes with attractive antibacterial activities witness the practical use for tissue engineering such as wound dressing.

“…Several previous studies have reported anti-microbial activity on REE nanomaterials [6][7]9]. Parvathya and Venkatramanb have investigated the differences in the synthesis methods due to the antimicrobial activity, i.e., green synthesis (G-CeO2) and chemical synthesis (C-CeO2).…”

“…Parvathya and Venkatramanb have investigated the differences in the synthesis methods due to the antimicrobial activity, i.e., green synthesis (G-CeO2) and chemical synthesis (C-CeO2). The results showed that G-CeO2 nanoparticles had higher activity than C-CeO2 against Escherichia coli, Pseudomonas aeruginosa, Streptococcus pneumonia, and Proteus Vulgaris bacteria [7]. The CeO2 nanoparticles also obtain a good antibacterial activity towards both gram-negative and positive bacteria because it has Ce 3+ ions and rich surface oxygen vacancies [8].…”

Cerium oxide (CeO2) and Neodymium oxide (Nd2O3) nanoparticles using local content have been synthesized by precipitation method. The CeO2 and Nd2O3 nanoparticles were characterized by X-Ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) to analyze the material phase and structure. The XRD spectrum shows that CeO2 and Nd2O3 nanoparticles have face-centered cubic and hexagonal, and cubic, respectively. The anti-microbial activity of CeO2 and Nd2O3 nanoparticles was analyzed by diffusion method using gram-negative bacteria (E.coli, S.aeureus, P. aeruginosa), and gram-positive bacteria (S. entericatyphi, L. monocyogenes), and fungus (C. albicans). The result confirms that CeO2 and Nd2O3 nanoparticles have the capability of patogen microbia inhibition. The CeO2 nanoparticles have the effective activities of inhibition for the microbia of S. aereus and S. entericatyphi, whereas Nd2O3 nanoparticles can inhibit the microbia of P. aeruginosa, S. entericatyphi, and L. monocyogenes.

“…Але недоліком є те, що в деяких випадках отримані частинки неоднорідні за морфологією, здатні до агломерації та мають широкий розмірний діапазон. Використовують в якості стабілізуючого агента й органічні сполуки (біополімери): дубильну кислоту[89,90], пектин (40 нм)[91], хітозан (23 нм)[92]. Існують спроби синтезувати наночастинки «зеленим» методом, використовуючи поживні речовини, такі як свіжий яєчний білок (8-18 нм)[93] або, наприклад, мед (23 нм)…”
