objective(s): bacterial biofilm formation causes many persistent and chronic infections. the matrix protects biofilm bacteria from exposure to innate immune defenses and antibiotic treatments. the purpose of this study was to evaluate the biofilm formation of clinical isolates of pseudomonas aeruginosa and the activity of zinc oxide nanoparticles (zno nps) on biofilm. materials and methods: aft...

Cerium orthovanadate nanoparticles (CeVO4 NPs) were fabricated using urea-assisted facile sol-gel auto combustion method. X-ray diffraction (XRD) pattern revealed the crystal planes and size of synthesized CeVO4 NPs. The morphological shape and the crystalline nature of the NPs were examined by field emission scanning electron microscopy (FESEM). Energy-dispersive X-ray spectroscopy (EDX) affir...

   In the present study, various size of Zinc Oxide Nanoparticles (ZnO NPs) was synthesized via Sol-gel method. The photocatalytic activity of the synthesized ZnO NPs was investigated for the Decolourization of three different colored dyes viz. Congo Red, Acid Blue 9 and Coomassie Brilliant Blue R-250 under UV lamp. Zinc Chloride (Zncl2) and Sodium Hydroxide (NaOH) were ...

because most contaminants in water create strong interactions with hydrophobic surfaces, there are usually problems such as flux decline and pore blocking in polyethylene (pe) membranes due to irreversible adsorption of foulants on their intrinsic hydrophobic surface. therefore, in this work, attempts were made to improve the properties of pe membranes in terms of water flux and membrane foulin...

Synthesis and characterization of Cd-TiO2/PEG/FA nanocomposite as a biomaterial is the main aim of this research. Cd-doped TiO2 nanoparticles (NPs) were synthesized by solvothermal assisted sol-gel method. Then, polyethylene glycol (PEG) was added to the as-synthesized NPs in order to modify their surface and to prevent agglomeration. In the next step, folic acid (FA) was conjugated to Cd-TiO2/...

Radioisotopes are useful tracers because their chemical properties are the same as those of stable isotopes and they show higher detection sensitivity than other tracers. Their usefulness has been demonstrated in fluorescence experiments in diverse areas including life science, medicine, and engineering. SiO2-coated radioisotope Au coreshell nanoparticles (Au@SiO2 NPs) were first synthesized by...

Anatase titanium dioxide nanoparticles (TiO2-NPs) were synthesized by sol-gel method using rice straw as a soft biotemplate. Rice straw, as a lignocellulosic waste material, is a biomass feedstock which is globally produced in high rate and could be utilized in an innovative approach to manufacture a value-added product. Rice straw as a reliable biotemplate has been used in the sol-gel method t...

preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of nile red-loaded solid lipid nanoparticles. nanoparticles (nps) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. to solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...
