A Novel Route for the Preparation of Gold Nanoparticles in Polycaprolactone Nanofibers
Journal of Nanomaterials, Volume 2015, Issue 1, 2015., 2015 A facile strategy for the fabrication of polycaprolactone (PCL) nanofibers containing gold nanoparticles (AuNPs) is proposed. The method is based on electrospinning nanosuspensions loaded with passivated Au nanoparticles. The optical property of gold nanoparticles synthesized was observed by UV‐visible absorption spectra.
