Synthesis and characterization of chitosan/ZnO nanoparticle composite membranes

The Study Effects of Dental Composite Resin as Antibacterial Agent Which Contain Nanoparticles of Zinc Oxide on the Bacteria Associated with Oral Infection

“…In this technology, the materials are converted into Nano metric sizes in order to produce a new Properties for these materials [31,32]. Nanoparticles possess unique physic-chemical, biological and optical properties in which can be manipulated for suitable desired applications [33].…”

“…the current study made an attempt to evaluation the antibacterial properties of composite resins containing zinc oxide nanoparticles against Streptococcus mutans, Pseudomonas areuginosa , Staphylococcus aureus and Klebsiella.spp (some species of gram positive and gram negative bacteria) , which have a significant role in recurrentcaries . Zinc oxide is a safe bactericidal metallic oxide (inorganic agent) because it isnon-toxic to animal cells in low concentrations but is very toxic to bacteria, killing them, although, the metals and metallic oxides as zinc oxide, are considered toxic to human cells at highconcentrations, they do not seem to be toxic at very low concentrations on human cells [32,[39][40][41]. In present study that was conducted on (50) caries samples , 26 isolates of bacteria from all caries specimens showed positive results due to bacterial culturing of these samples which are positive for male and female patients respectively as seen in Table 2, anyhow, our results were consistent with workers [42] observation .…”

BIOSYNTHESIS OF ZINC OXIDE NANOPARTICLES FROM Glycyrrhiza glabra Linn FOR ANTIMICROBIAL, ANTICANCER AND PHOTOCATALYTIC APPLICATIONS

“…The synthesized zinc nanoparticle was characterized by using FTIR, UV-VIS, and SEM methods. [8] www.wjpps.com …”

“…After incubation, the zone of inhibition of different bacteria was observed. [8] Anticancer Study against Liver Cancer Cell Line RPMI medium was used to study the anticancer activity of HEPA-2 cancer cell lines. 5ml…”

Preparation, characterization and rheological behavior of chitosan nanocapsule emulsion encapsulated tuberose fragrance

“…Chitosan, a natural plentiful biopolymer obtained by chitin deacetylation, mainly consists of the repeating unit of 2-amino-and 2-acetamido-2--deoxy-β-D-glucopyranose. Due to its unique properties such as favorable biological properties 5 , antimicrobial activity 6 , low toxicity, biodegradability 7 and proper mucoadhesive properties 8 , Chitosan has been extensively applied in various fi elds, such as biotechnology 9 , food ingredients 10 , pharmaceuticals 11 , waste water treatment 12 and cosmetics 13 . Sodium tripolyphosphate is an anionic cross-linker.…”
