Nano Copper have considered as an alternative noble metals in many applications, such as heat transfer and microelectronics. The microfabrication of conductive features like ink-jet printing. Electronic devices have utilized noble metals like gold and silver for printing highly conductive elements. While the cost of noble metals is very high, copper is a low-cost and conductive material.

Nano Copper the large extinction creoss section and photosensitivity nanostructures make platforms as highly sensitive opticals nanosensors, photonic components and in surface-enhanced spectroscopies. LSPR is excited when light (Electromagnetic radiation) interacts with the free (conduction) electros of ametalic nanostruture. Which result in the collective of the local electromagnetic fileds surrounding the nanoparticles.

Nano Copper are very interesting, because they show unique nanoscale phenomena like plasmonic absorption and high surface to volume ratio, but also due to useful properties like antibacterial and fungicidal activity. Copper 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.

Nano Copper 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 used in thin carbon layers in the production of electrodes capable of carbon hydrate detection, CO gas sensors and biosensors.

Nano Copper 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.Flax fiber was modified by copper nano particles, which, then, to add antimicrobial properties, was introduced into polyethylene and poly(vinyl methyl ketone) films.
