Scientific Article
The Honorable Mrs. Dean of the College of Education for Pure Sciences, Prof. Hamida Idan Salman, obtained the acceptance to publish a scientific article titled (Silver Nanoparticles AgNPs) by the Scientific Articles Committee at the Presidency of Karbala University after fulfilling all publication conditions. (Prof. Dr. Hamida Idan Salman) stated that the term nanoparticles and nanotechnology has become common at the present time and is widely spread, but the meaning of this term must still be defined, nanoparticles are solid particles with a size within the range of 10-1000 nanometers. As for nanotechnology, it refers to any technology that is implemented at the nano level, where the material is restructured at the atomic and molecular levels with a size within the range of 1 – 100 nanometers. This technology is interdisciplinary, covering a wide variety of sciences from engineering, biology, physics and chemistry. When the dimensions of a material are reduced from a large size, the properties initially remain the same, then small changes occur and finally when the size is less than 100 nm, drastic changes in the unique physical and chemical properties can occur. Nanotechnology has made tremendous progress over the past decades, especially between 2005 and 2010, where its development has increased significantly and exponentially from previous years, in the number of products that contain or require nanoparticles for their production. This development is supported by their unique general properties in particular particle size, wide surface area, high chemical stability, surface reactivity, charge, and shape relative to their regular size counterparts. Nanotechnology has been developed as a new strategy in the field of antimicrobials to put an end to resistant microbes. Metal nanoparticles such as platinum, copper, silver and gold contain antimicrobials against bacteria that cause fungi and various diseases. In particular, silver nanoparticles had promising applications in nanotechnology and medicine, and it was approved for its bactericidal activity against bacterial infections as well as antiviral and antifungal effects that cause various diseases. Among the nanometals, silver nanoparticles have been used since the 1880s. Because silver has broad spectrum antimicrobial activity against a wide range of microorganisms. Silver nanoparticles have received unlimited attention due to their exceptional properties such as chemical stability, catalytic activity, excellent conductivity, and most importantly as antimicrobial and antifungal against fungal species such as Aspergillus fumigatus.
