Copper Nanoparticles  is of importance that the toxicity of copper nanoparticles is from 2.5 to 6 times less than that of copper(II) salts. Copper nanoparticles have reavealed a strong anibacterial activity and decrease the microorganism concentration the stability of copper nanoparticles a matrix and their disinfecting properties, copper nanoparticles can be used as a bactericide hostipital equipment.

Cu Nanoparticles Application in the felied of catalysis Cu particles are widely used in fields of lubricants ploymers/plastic,metallic coating and ink.Copper Nanopowder sulfide has potential application in solar cells detetors and lubricants. Anti-microbial efects of metal nanoparticles received considerable attention from both medical and technological point of view. Metallic Cu particles was used as an anti-infective agent for replacing Ag and other noble metal composites applications such as water treatment, food processing and protection of medical instruments.

Copper Nanoparticles are the leading in the field of nanomedicine and in that  nanotoxicology is graning great importance. Copper as an antimicrobial agent which is to reduce specific harmful bacteria  to potentially deadly microbial infection. Applications 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,  alloys, in nanowire, nanofiber, super strong metals in certain alloy and catalyst application.

Copper Nanoparticles Used electrical power while on synthesizing of copper nanoparticles is increasing its antibacterial activities. The chemicals involved in the synthesis of nanoparticles are commonly available, cheap, and non-toxic. Copper nanopowder have reavealed a strong anibacterial activity and decrease the microorganism concentration the stability of copper nanoparticles a matrix and their disinfecting properties,copper nanoparticles can be used as a bactericide hostipital equipment.

Copper Nanopowder have excellent physical and chemical properties and low cost of preparation, have been of great interest. Cu nanopowder 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.
