Özet

Nowadays, the most important problem in microbial researches is bacterial resistance which is carried out by DNA plasmids against antibacterial agents. The effect of antibacterial nanoparticles on bacteria is remarkable, but studies on the interactions of these particles with plasmids do not search or there are no adequate studies. We proposed that the nanoparticles, which are disrupted the self-assembled structure of plasmids, may decrease the resistance of bacteria, and therefore, increase the activity of utilized antibacterial agents. In this work, we synthesized polymer nanofiber webs samples by electrospinning technique from pure water solution of nanocomposites with different contents of silver nanoparticles, and surface morphology of nanofibers composites were characterized by SEM microscopy. Their interactions with pMAD DNA plasmids were investigated. It was demonstrated that the synthesized Ag-carrying nanohybrid composites with higher surface contacted areas were significantly inhibited the activity of plasmid DNA against bacterial resistance. Agreeing with obtained results, synthesized nanofiber coatings can be recommended for the widely applications in nanobiotechnology, nanomedicine, and bioengineering processing. (C) 2014 Elsevier B.V.
