Preparation of Titanium Dioxide Nanoparticles and PolyVinyl Pyrrolidone Polymer Films as Antibacterial, Antibiofilm against Pathogenic Bacteria on Different Surfaces

ANTIBACTERIAL AND ANTIBIOFILM EFFICACY OF COPPER DOPED ZnO NANOPARTICLES AGAINST MARINE BIOFILM FORMING BACTERIA

The antibacterial and antibiofilm activity of chemically synthesized pure and Cu doped ZnO nanoparticles against marine biofilm forming bacteria has been reported for the first time. The synthesized nanoparticles were characterized using PXRD, FTIR and SEM which confirmed the formation of phase pure nanostructured zinc oxides. The antibacterial and antibiofilm activities of the synthesized nano...

Effects of Solvent on the Structure and Properties of Titanium Dioxide Nanoparticles and Their Antibacterial Activity

Titanium dioxide is semiconductor metal oxide having many applications in photocatalytic activities, cosmetics and in the food industry. It exists in three major crystalline forms: anatase, rutile and brookite. The solvents play a major role in the synthesis, stability and morphology of the metal oxide nanoparticles. It affects both the phase and particle size of metal oxide. T...

Synthesis, Characterization and Antibacterial Properties of Titanium Dioxide Nanoparticles

DNA/Ag Nanoparticles as Antibacterial Agents against Gram-Negative Bacteria

Silver (Ag) nanoparticles were produced using DNA extracted from salmon milt as templates. Particles spherical in shape with an average diameter smaller than 10 nm were obtained. The nanoparticles consisted of Ag as the core with an outermost thin layer of DNA. The DNA/Ag hybrid nanoparticles were immobilized over the surface of cotton based fabrics and their antibacterial efficiency was evalua...

Biosynthesis of Titanium Dioxide Nanoparticles from the Mangrove (Avicennia marina) and Investigation of its Antibacterial Activity

Background and purpose: Development of biocompatible and nontoxic methods for synthesis of nanoparticles is important in bio-nanotechnology. This study aimed at biosynthesis of titanium dioxide nanoparticles (TiO2 NPs) using leaf of the native mangrove (Avicennia marina) and investigating its antibacterial activity. Materials and methods: Effect of four different solutions composed of dry extr...
