“…The use of nanotechnology for the production of antibacterial agents aiming to control and treat bacterial infections has already been applied [34][35][36][37], corroborating our results. The silver nanocomposite developed can be an alternative to conventional antibiotics, with special importance in multidrug-resistant bacteria [38,39].…”

Abstract:Bacterial resistance is an emerging public health issue that is disseminated worldwide. Silver nanocomposite can be an alternative strategy to avoid Gram-positive and Gram-negative bacteria growth, including multidrug-resistant strains. In the present study a silver nanocomposite was synthesized, using a new green chemistry process, by the addition of silver nitrate (1.10 −3 mol·L −1 ) into a fermentative medium of Xanthomonas spp. to produce a xanthan gum polymer. Transmission electron microscopy (TEM) was used to evaluate the shape and size of the silver nanoparticles obtained. The silver ions in the nanocomposite were quantified by flame atomic absorption spectrometry (FAAS). The antibacterial activity of the nanomaterial against Escherichia coli (ATCC 22652), Enterococcus faecalis (ATCC 29282), Pseudomonas aeruginosa (ATCC 27853) and Staphylococcus aureus (ATCC 25923) was carried out using 500 mg of silver nanocomposite. Pseudomonas aeruginosa and Acinetobacter baumannii multidrug-resistant strains, isolated from hospitalized patients were also included in the study. The biosynthesized silver nanocomposite showed spherical nanoparticles with sizes smaller than 10 nm; 1 g of nanocomposite contained 49.24 µg of silver. Multidrug-resistant strains of Pseudomonas aeruginosa and Acinetobacter baumannii, and the other Gram-positive and Gram-negative bacteria tested, were sensitive to the silver nanocomposite (10-12.9 mm of inhibition zone). The biosynthesized silver nanocomposite seems to be a promising antibacterial agent for different applications, namely biomedical devices or topical wound coatings.

“…TiO 2 nanoparticles are reported to show antimicrobial activity against P. gingivalis, having a minimum inhibitory concentration (MIC) value of 2.5 mg/mL 24) . It is thought that nanoparticles accumulate on cell membranes, the permeability of which becomes compromised, rendering the cell unable to regulate transport, hence leaking intracellular components and eventually causing cell death.…”

We focused on the antimicrobial effects of titanium dioxide (TiO2) after stopping ultraviolet (UV) irradiation as an adjunctive treatment for peri-implantitis in this study. The aim was to determine the continuous photocatalytic effects of TiO2 after UV irradiation and its antimicrobial activity against periodontal pathogen. The continuous photocatalytic effects of TiO2 after UV irradiation were determined by electron spin resonance (ESR) spectroscopy using TiO2 particles of various sizes with various UV irradiation times. In addition, antimicrobial activity against Porphyromonas gingivalis was investigated by quantitation of colony-forming units (CFUs). The results showed that the ESR signal ratio for the UV-irradiated TiO2 was significantly higher than that of the non-irradiated TiO2. UV-irradiated TiO2 significantly reduced the number of P. gingivalis when compared with non-irradiated controls. These results suggest that TiO2 has a continuous photocatalytic effect even after stopping UV irradiation and that it showed antimicrobial activity against periodontal pathogen.

“…12,13 Miguel A found that nano Ag has pathogens. 13 Recent studies have attempted to combine HA with Ag 14 by chemical precipitation or microwave accelerated synthesis method 15 and assess antibacterial and biological safety of different loads, and 0.5 AgHA was found exhibiting good antibacterial properties. 16 Considering the stable space structure and remarkable osseointegration of Bio-Oss V R and the attractive antibacterial activity of AgHA, peri-implantitis might potentially be treated with a mixture of AgHA and Bio-Oss V R .…”
