“…A bactericidal effect has also been seen on P. aeruginosa with a minimum inhibitory concentration of 0.06 mg/L [49]. Another study reports on the bactericidal activity of nanostructured hematite against a variety of Grampositive and Gram-negative bacteria; P. aeruginosa, S. aureus, K. pneumoniae, Lysinibacillus sphaericus and Bacillus safensis [50]; proposing some mechanisms of action depending on the activity observed in each stage of the growth of the bacteria in question. A bactericidal effect of NPs of Fe 2 O 3 against S. epidermidis has even been determined [51].…”

In recent years, infectious diseases, specifically those that are caused by pathogens, have seen a dramatic proliferation due to resistance to multiple antibiotics, opening the colony by opportunistic pathogens. Nanotechnology and tissue engineering have been applied in the development of new antimicrobial therapies, capable of fighting opportunistic infections. In the medical field, research on antimicrobial properties of metal oxide nanoparticles have emerged to find new antimicrobial agents as an alternative against resistant bacteria. The metal oxides, particularly those formed by transition metals are compounds with electronic properties, and most magnetic phenomena involve this type of oxides. Nanoparticlesbased metal oxide properties such as shape, size, roughness, zeta potential and their large surface area, make oxides ideal candidates to interact with bacteria and able to have an antimicrobial effectiveness. The aim of this chapter is to offer an updated panorama about the relationships between the use of metal oxide nanoparticles in the medical field, with an emphasis on their role as antimicrobial agents and the properties that influence their antimicrobial response. In addition, the mechanism of nano-antimicrobial action is described and the importance of using in vitro test methods, adopted by leading international regulatory agencies, that can be used to determine the antimicrobial activity of the metal oxide nanoparticles.

In this study, silver oxide nanoparticles (Ag 2 O-NPs) were synthesized from silver nitrate using green amaranth leaf extract as reducing agent. The degradation of caffeine and inactivation of Escherichia coli by Ag 2 O-NPs was studied under compact uorescent lamp illumination irradiation. Apart from that, the antibacterial and antioxidant activities of Ag 2 O-NPs were also examined. Synthesized Ag 2 O-NPs were shaped like monodispersed husk, and cubic structured with surface area and average particle size was detected to be 100.21 (m 2 /g) and 81 nm respectively. Antioxidant e cacy of the Ag 2 O-NPs was evaluated using 1, 1-diphenyl-2-picrylhydrazyl and 91% inhibition was achieved with 100 µg Ag 2 O-NPs.Bacteriocidic propensity of Ag 2 O-NPs was examined against the S. aureus and P. aeruginosa by disc diffusion, minimum inhibitory concentration (MIC), Live and dead assay. It was observed that the NPs have higher bactericidal effect on Gram-negative as compared to Gram-positive bacteria. Up to 96% photocatalytic inactivation of E. coli was achieved using 30 µg/mL of NPs, Photocatalytic degradation of caffeine (50 ppm initial concentration) was observed to be 99% at pH 9 in 15 h using 50 mg/L of Ag 2 O NPs. These results indicate that Ag 2 O NPs can be employed in environmental applications like harmful bacteria inactivation and organic pollutants degradation.

“…También se ha visto un efecto bactericida a P. aeruginosa con una concentración mínima inhibitoria de 0.06mg/L (Irshad et al, 2017). Otro estudio informa sobre la actividad bactericida de la hematita nanoestructurada contra una variedad de bacterias Gram-positivas y Gram-negativas; P. aeruginosa, S. aureus, K. pneumoniae, Lysinibacillus sphaericus y Bacillus safensis (Muthukumar et al, 2017); proponiendo incluso algunos mecanismos de acción dependiendo de la actividad observada en cada etapa del crecimiento de la bacteria en cuestión. Incluso se ha llegado a determinar un efecto bactericida de nps de Fe 2 O 3 contra S. epidermidis (Groiss et al, 2017).…”

Actualmente existe un gran interés en Centro de Ciencias Aplicadas y Desarrollo Tecnológico (CCADET) de la UNAM, por el desarrollo de métodos innovadores que permitan obtener materiales nanoestructurados y en particular aquellos formados por óxidos metálicos, con actividad antimicrobiana. En este artículo se presenta lo que el grupo de investigación de la Dra. América Vázquez ha llevado a cabo sobre la mecanosíntesis de una serie de óxidos nanoestructurados formados por CuO, CuBi2O4, ZnO, Mn3O4, Fe2O3, CuFe2O4, ZnFe2O4 y MgO, así como una revisión sobre las aplicaciones de dichos óxidos, como agentes antimicrobianos. La principal motivación de esta investigación radica en el hecho de que el desarrollo de nuevos antibióticos, a pesar de ser constante, resulta inútil cuando los microorganismos se vuelven multirresistentes. Por tal razón, se han buscado nuevas formas de combatir dichas infecciones y en este sentido, las nanopartículas (NPs) formadas por óxidos metálicos han resultado ser una nueva herramienta en la lucha contra las enfermedades causadas por microorganismos que cada vez se vuelven más resistentes a los tratamientos convencionales con diversos antibióticos.
