Researchers of Isfahan Biotechnology and Bioengineering Research Institute have created a new kind of silver–magnetic nanocomposite which can be applied for water purification.

According to an ISCA report, there is a need for protecting and tidying up the natural resources of water, largely polluted by human activities. Impure water leads to health issues, especially in rural areas. Though various techniques had been used for years to purify water, research is still carried out to find out advanced treatment protocols.

In this regard, researchers carried out this research to create silver nanocomposites, investigate its antibacterial property, also to remove water contaminants, “in order to keep the antimicrobial properties of silver, we used a composite with silver coating,” said the research project executor, Seyed Amir Hossein Jalali.

Magnetic nanomaterials like iron oxide (Fe3O4) are very promising materials used in water decontamination particularly for heavy metals and dyestuffs because of their ease of separation through external magnet, high surface area, unique morphology as well as their high stability, therefore he noted that due to its magnetic properties, we also used iron to create a magnetic field and remove the contaminants present in water.

Eliminating water pathogens and medical waste treatment as well as producing nanomedicine are some applications of this research.
