Evaluation of Morphological and Ultrastructure Effects of Nanoparticles on Some Microbial Cells

Abstract

NPs having a size of 1-100 nm in one dimension could be used in many fields, such as medicine, chemistry, atomic physics, and all other known fields, which can be used immensely due to their small size, as they showed new or improved properties, in the distribution, size, and morphology of the particles. One type of those NPs is AgNPs could be synthesized using various approaches including physical, chemical, and biological methods. Among all of the NPs synthesis methods, biosynthesis method is the safest, cheapest, and produces large quantities. Those NPs could be used as antimicrobial agents as they could strongly interact with thiol groups of vital enzymes and inactivates them. In addition, DNA loses its replication ability once the bacteria have been treated with silver ions, and other studies have shown evidence of changes in the structure of cell membrane, so these NPs could be used as a treatment for infection of dermatophyte
