제목 Highly sensitive metal-enhanced fluorescence biosensor prepared on electrospun PCL fibers decorated with silica-coated silver nanoparticles
초록 A new MEF-based biosensor platform was prepared on fibrous substrates. First, PCL fibers were obtained via electrospinning. PCL fibers were decorated with photoreduced silver nanoparticles followed by silica coating, generating silver-decorated PCL fibers with a silica layer. The silica layer acted as a spacer between the silver nanoparticles and the fluorescent molecules to optimize the MEF effect. The MEF was obtained from the silver-decorated PCL fibers, the extent of which could be controlled by the thickness of the silica layer. The fibrous structure of Ag@SiO2-PCL had higher protein loading capacity than conventional two-dimensional glass slides due to its large surface area, while the presence of silica-coated silver nanoparticles resulted in higher fluorescence intensity than SiO2-PCL without silver nanoparticles via the MEF effect.
