| Abstract |
Dual probe porphyrin-gold nanorod polyelectrolyte microcapsules were developed to explore the enhancing effects of a plasmonic interface of self-assembled gold nanoparticles in the fluorescence emission from porphyrins loaded into the capsules core. An analysis of fluorescence lifetime imaging microscopy (FLIM) data reports a notable 10(5)-10(6)-fold increase in the maximum detected photon rates from diffraction-limited spots and an overall six-fold increase in fluorescence as averaged over the whole microcapsule area. Large emission enhancements were correlated with decreases in fluorescence lifetimes. The microcapsule s design proved effective in achieving high fluorescent hybrids and may shed light on new possibilities for advanced materials imaging applications. |
