CuO is one of the most important intermediate metal oxides with unique properties, used in various technological applications such as superconductors, gas sensors. Recently, CuO has been used as an antimicrobial agent against numerous bacterial species. In the present study, we synthesized copper oxide nanoparticles and investigated its antimicrobial activity and therefore colour of copper oxide nanoparticles depends on many factors .The use of plant extract in phytosynthesis of nanoparticles can be used as a nature-friendly method and a suitable alternative to conventional methods such as physical and chemical methods.
How specify different nanoparticles form each other?
Nanomaterials differ in atomic structure, crystallographic directions, or chemical composition. All materials, including metals, semiconductors, glass, ceramics and polymers, can exist in nanoscale dimensions. The range of nanotechnology can also be in the form of amorphous, crystalline, organic, inorganic or single particles, complexes, powders, colloids, suspensions or emulsions. In general, materials have three dimensions of length, width and height. If at least one of these dimensions is at the nanotechnology scale (1-100 nm), it is called nanostructured material. Nanostructured materials are subdivided into different subdivisions depending on how many dimensions they have on the nanotechnology scale. One of these is in terms of the number of free dimensions. By free dimension, it is a dimension that is not nanoscale and can have any value. The materials are divided into four categories:
- Nano Particles
- Nano Wiers
- Thin Films
- Bulk Nanomaterials
Synthesis and Biomedical Applications of Copper Oxide Nanoparticles
Copper nanoparticles that are very small and have a high surface-to-volume ratio can also act as antifungal / antibacterial agents. Antimicrobial activity is caused by their close interaction with microbial membranes and the release of metal ions in the solution. As the nanoparticles are slowly oxidized in the solution, copper ions are removed and when the adipose membrane is adjacent to them, they can form toxic hydroxyl free radicals. Then, free radicals secrete lipids into the cell membrane through oxidation to destroy the membrane. As a result copper oxide preparation, the intracellular material is released through the destructive membranes; cells are no longer able to maintain basic biochemical processes. In the end, all these changes within the cell that are caused by free radicals cause cell death.
History of nanoparticles using around the world
One of the first uses of copper nanoparticles was to paint glass and pottery in the ninth century in Mesopotamia. This was done by making a glaze of copper and silver salt and adding it to the potting soil. When the jar was cooked at high temperatures, under reduced conditions, the metal ions were transferred to the outer part of the glaze and reduced to metal and this was an example of copper oxide nanofluid properties. The end result was two layers of metal nanoparticles with a small amount of glaze between them. When the cooked jar was exposed to light, the light penetrated and reflected from the first layer. The light penetrated from the first layer was reflected by the second layer of the nanoparticles, and by the reflected light from the first layer it produced the interference effect of the waves, which gave these pitchers a luminosity.

The history of developing nanotechnology laboratory concepts and work is in the range of research activities. Although nanotechnology is a relatively new development in scientific research, the development of its core concepts has taken place over a longer period of time. The advent of nanotechnology in the 1980s was due to the convergence of experimental developments such as the invention of the scanning tunneling microscope in 1981 and the discovery of fullerenes in 1985. In the early 2000s we also saw the start of commercial advertising of nanotechnology, though these were limited to major applications of nanomaterials, the developmental programs anticipated by the field.
