The metals-based nanofibres are considered as new candidate for increasing many properties (from mechanical to biological properties) of non-active fibres in distinct applications such as drug delivery, tissue engineering, and gas sensors, etc. The aim of this work is to involve a method for preparing polymeric nanofibrous containing nanoalloy and to improve the properties of obtained fibers. Through this aim, the one-dimensional (1D) nanofibres (NFs) of polyacrylonitrile (PAN) having gold-silver nanoparticles (2 wt%) were fabricated using electrospinning technique. After alloying the PAN NFs, a significant reduction the water contact angle for AuAg-PAN NFs was noted compared to PAN NFs. Also, tensile test of as-prepared samples exhibit that the mechanical properties of AuAg-PAN NFs better than pristine PAN NFs. All samples were studied by XRD, FESEM, AFM, and FT-IR techniques. Biocompatibility of PAN NFs, and its corresponding fibers alloyed with AuAg (NPs) were tested by MTT (3-(4, 5-dimethythiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay, which demonstrates a good proliferation rate for cells on AuAg-PAN NFs surface. All results have approved that the bimetallic phase with smaller particle dimensions revealed remarkable improvement of the most of the virtues as compared to PAN NFs.
