Metal Nano Powder

Copper Nanopowder  synthesized by three different mathod chemical, physical and biological. Method use to synthesis copper nanoparticles to micromulsions, reverse maicelles, gamma, irradiation, ultravoilet irradiation. Sonochemical, termal decompostion biological method in which living organisms such as plant and bacteria are uesd to synthesize copper nanoparticles. Stable Copper nanoparticles can also synthesized in toluene, dodecanthiol, with lauric acid as aprotective agent borohydride as reducing agent.

Copper Nanopowder  fungicides are extremely effective against certain species of fungi that are common agricultural pathogens. Copper nanoparticles show good to great antimicrobial property against many pathogenic microbes and also used as a commercial antimicrobial agent. Liquid copper dispersions are used as an antimicrobial spray or to prepare antimicrobial surfaces. Other copper nanoparticle applications include conductive ink, chemical sensors, bio sensors etc.

Copper Nanopowder  have excellent physical and chemical properties and low cost of preparation, have been of great interest. Copper nanoparticles have wide applications as heat transfer systems, super strong materials, sensors, and catalysts. Copper nanoparticles, which have wide applications in the production of CO gas and biosensors. Copper nnaoparticles due to their excellent physicals and chemiclas properties and low cost of perparation,have been of great interest.

Copper Nanopowder  Applications for copper nanocrystals include as an anti-microbial, anti-biotic and anti-fungal (fungicide) agent when incorporated in coatings, plastics, textiles, in copper diet supplements, in the interconnect for micro, integrated circuits, for its ability to absorb radioactive cesium, in super strong metals, alloys, in nanowire, nanofiber, in certain alloy and catalyst applications. copper nanoparticles synthesized in electrolysis method are showing antibacterial activities against both gram (-) and gram (+) bacteria.

Copper Nanopowder are copper based particles 1 to 100 nm in size. metallic copper nanoparticles (Cu-NPs), which had high potency for bacterial cell filamentation and cell killing. The present study deals with the mechanism of filament formation and antibacterial roles of Cu-NPs in E. coli cells. Cu-NPs were found to cause multiple toxic effects such as generation of reactive oxygen species, lipid peroxidation, protein oxidation and DNA degradation in E. coli cells.
