Preparation of electrospun antibacterial nylon nanofibers through in situ synthesis of nanosilver

The aim of this study is the preparation of antibacterial nylon nanofibers containing silver nanoparticles (nylon nanofibers/Ag NPs) via in situ synthesis of nano-silver by reduction of silver nitrate prior to electrospinning. The structure and properties of the electrospun fibers and electrospinning solutions were studied using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX), UV-Vis spectrophotometer and reflection spectrophotometer. In addition, the antibacterial properties of the nanofibers were investigated against Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive) bacteria. It was revealed that the nylon nanofibers/Ag NPs showed excellent antibacterial activity. The synthesized nylon nanofibers/Ag NPs can be a good candidate for biomedical applications, water and air filtration.
