“…The treatment of P. aeruginosa ATCC 9027 for 24h with 100, 50, 25 and 12.5μg/ml decreased bio lm activity at 97.75%, 88.5% , 80.44% and 76.37 %, respectively. Based on these results, we conclueded the BaFeO 3-δ perovskite nanomaterials may be used to inhibit the activity of bio lms [12].…”

“…In spite of the extensive studies on antibacterial nanomaterials, new and less expensive nanomaterials are needed because of the increasing number of bacterial strains [11]. The perovskite nanomaterials as antibacterial and antibio lm agent is a new and growing area in the eld of medicine because of the size of bacterial cell and its membranes are micrometers and nanometers sizes, respectively [12]. Less expensive perovskite nanomaterials were used as antibacterial agent such as SrFeO 3-δ , SrTi 1-x Fe x O 3 (x=0, 0.2, 0.4, 0.6, 0.8 and 1) and Ba(Zr x Ti 1-x )O 3 (x=0.05) [10,13,14].…”

BaFeO3-δ perovskite nanomaterials have been synthesized by two different methods: co-precipitation (Cop) and sol-gel (Sol) methods. Rietveld analysis of the X-Ray diffraction (XRD) shows that the samples are crystallized in rhombohedral perovskite structure with space group R3c. Scanning electron microscope (SEM) of these samples showed the agglomerations of various particles. Dynamic light scattering (DLS) showed that the average particle size of BaFeO3-Cop sample is larger than that of BaFeO3-Sol sample. The amount of oxygen deficient (δ) and the valence states of Fe ions in these samples were determined from Mössbauer spectroscopy. X-ray photoelectron spectroscopy (XPS) shows the elemental compositions and surface electronic states of these samples. The thermal, optical and magnetic properties of these samples depend on the amount of oxygen deficient (δ) and the valence states of Fe ions. Furthermore, the antibacterial and antibiofilm activity of these samples was systematically investigated. The present results suggest that BaFeO3-δ superparamagnetic perovskite can be used as antibacterial and antibiofilm agent.

“…SiC NPs were proven to enhance the antimicrobial activity of other materials when used as additives, showing improved in vitro results against E. coli and S. aureus [ 115 ]. Other ceramic nanoparticles of interest against inner ear-related pathogens are lithium niobate (LiNbO 3 ) [ 1 ], silicon nitride (Si 3 N 4 ) [ 116 ], titanium carbide (TiC) [ 117 ], and barium titanate (BaTiO 3 ) [ 118 ].…”

Nanoparticles for the Treatment of Inner Ear Infections

et al. 2021

The inner ear is sensitive to various infections of viral, bacterial, or fungal origin, which, if left untreated, may lead to hearing loss or progress through the temporal bone and cause intracranial infectious complications. Due to its isolated location, the inner ear is difficult to treat, imposing an acute need for improving current therapeutic approaches. A solution for enhancing antimicrobial treatment performance is the use of nanoparticles. Different inorganic, lipidic, and polymeric-based such particles have been designed, tested, and proven successful in the controlled delivery of medication, improving drug internalization by the targeted cells while reducing the systemic side effects. This paper makes a general presentation of common inner ear infections and therapeutics administration routes, further focusing on newly developed nanoparticle-mediated treatments.

“…Recently, some studies made on model system (polystyrene well plates) and real systems (fresh pineapple, tofu, and lettuce) indicated that nanoemulsions of EOs have significantly higher antibiofilm activity compared to pure EOs ( Table 2). Antimicrobial efficacy of nanoemulsions is dependent on the droplet size and electrical properties of nanoemulsions [102,103], nature of bacteria [75,104], and food matrix [105][106][107].…”

This chapter presents the ability of some pathogenic (Listeria monocytogenes, Escherichia coli, Salmonella enterica, Campylobacter jejuni, Pseudomonas aeruginosa) and toxigenic bacteria (Bacillus cereus, Staphylococcus aureus) to form biofilms and contribute to the persistence of these microorganisms in the food industry. Particularities regarding attachment and composition of biofilms formed in food and food processing environments are presented and genes involved in biofilm production are mentioned. To give a perspective on how to fight against biofilms with new means, nonconventional methods based on bacteriocins, bacteriophages, disruptive enzymes, essential oils, nanoemulsions and nanoparticles, and use of alternative technologies (cold plasma, ultrasounds, light-assisted technologies, pulsed electric field, and high pressure processing) are shortly described.
