Au nanostructures by colloidal lithography: from quenching to extensive fluorescence enhancement

Au nanostructures by colloidal lithography: from quenching to extensive fluorescence enhancement

Enhanced local electric fields are created by nanoparticles when pumped at wavelengths corresponding to Localised Surface Plasmon Resonance (LSPR) modes, leading to Metal Induced Fluorescence Enhancement (MIFE). This paper describes the fluorescent enhancement due to reproducible and tuneable Au nan...
