Gold Nanorod-loaded Electrospun Fibers:Preparation and Surface-enhanced Raman Spectroscopy Performance
摘要
Abstract
In this work, the highly active surface-enhanced Raman spectroscopy(SERS) substrate was fabricated by a simple and effective method.Electrospun polyvinyl alcohol(PVA)/polyacrylic acid(PAA) nanofibers were used as supporting material and a SERS substrate with excellent performance was obtained by a direct-immersed method due to the electrostatic force between gold nanorods and nanofibers.The morphologies of gold nanorods and electrospun fibers in different states were characterized by transmission electron microscopy and scanning electron microscopy.Gold nanorods are loaded uniformly and densely on the surface of fibers.The optimal assembly time of gold nanorods is 12 hours.By adjusting the spinning time and the concentration of gold nanorods, it was found that the SERS signal of the composite fiber membrane increased with the increase of the spinning time and the concentration of gold nanorods.The composite fiber membrane shows excellent SERS uniformity and the 4-aminothiophenol at a concentration of 10-10 mol/L can be detected.关键词
