Submicrometer Spatial Resolution of Metal-Enhanced Fluorescence [PDF]

open access: yesApplied Spectroscopy, 2003
Enhanced fluorescence emission intensity from fluorescein was observed on glass slides covered with thin films of silver nanoparticles using a confocal laser-scanning microscope. The silver nanoparticle film increased the emission intensity of fluorescein by an average of at least three-fold in the area studied.
