Acrylic nanofibers containing silver nanoparticles with an appropriate structure have been produced by researchers at Isfahan University of Technology, Iran, and their antibacterial properties against three common types of bacteria have been proved.
Ms. Qazal Naddaf prepared a homogeneous solution containing silver nanoparticles through a simple process and investigated parameters affecting the number, size, and distribution of nanoparticles. She, then, synthesized acrylic nanofibers containing silver nanoparticles with appropriate structure and analyzed the antibacterial property of synthesized nanofibers against three common types of bacteria.
"Our research results showed that silver nanoparticles could be synthesized by in situ reduction of silver ions in PAN/DMF solution after a definite time of xenon-arc irradiation without using any additive. Moreover, nanoparticles size and its distribution in colloidal solution could be controlled by parameters such as irradiation time and silver salt concentration," Naddaf said in an interview with the news service of INIC.
"The results of silver liberation and antibacterial properties also imply that nanofibers have good antibacterial properties and stability especially against pseudomonas aeruginosa", she added.
Noting that nanofibers are supposed to have a variety of applications in composites, filters, protective textiles, and medical and biomedical supplies, Naddaf reiterated that the addition of silver nanoparticles to these fibers could provide catalytic, optical, and antibacterial properties for them.
The results of the present research are available at Journal of Applied polymer science, volume 116, pages 1021-1029, 2010.
