  • Introduction: Considering the economic problems that exist in the country, the use of waste products such as Agricultural products are of particular importance. In Iran, annually, 1 million tons of dates are produced, the main consumption of which is during Ramadan. From the date product of Iran each year, 10% is allocated to exports to other countries, 50% is consumed internally and 40% at various stages of harvesting is lost. Many experiments have proved the effect of palm corner on diabetes, and its prevention of cancer. With the advancement of Nano science and technology and the diverse application of this science, various chemicals have been used to make nanostructures of a wide variety. This material is not only economically viable, but also has a lot of environmental effects. Therefore, the use of a green process for the production of nanostructures using waste from agricultural products is very important.
  • Methods: In this article, dates were collected randomly from the gardens of the Rigan area and their cores were separated. Alloys were used to synthesize powder nanostructures. In order to characterize the samples, scanning electron microscopy (SEM), X-ray diffraction pattern (XRD), measuring surface area and effective levels (BET) and thermal stability (TGA) were used.
  • Results: The morphology of these samples is spherical with an average particle size of 45 nm. In the structure, there was no evidence of particle agglomeration that indicates the high stability of the samples as well as the effective performance of the synthesis method. In order to determine the crystal size of the samples, XRD was taken. The breadth of the couriers is a strong reason for the dispersion of samples in the Nano range. According to the results of BET, the synthesized sample has an upper surface area of about 85 square meters per gram of sample, which confirms the nanostructure of the samples.
  • Conclusion: Application of these lesions as antibacterial nanostructures was investigated, Bacteria cannot grow well in the presence of nanostructures synthesized by the alloying process .and It can be a suitable substitute for nanoparticles like silver which are used as particles with high antibacterial properties. But today there are too much concerns about the toxic effects of silver nanoparticles in body. Researches have shown that harmful effects such as accumulation in the liver and kidneys and tissue necrosis can be caused by overuse of silver nanoparticles, destructive effects on the muscles, accumulation in the brain and the nervous system, and the development of a tumor, as well as environmental degradation effects. Leave behind considering the expected characterization techniques, it is anticipated that these inexpensive, accessible, and affordable compounds are available in various medical, environmental and industrial fields of applications.
