What is Metal Enhanced Fluorescence?

Metal Enhanced Fluorescence (MEF) is based on the reaction of excitation light with electrons of metal nano-structures to generate strong electromagnetic fields, also known as LSPs (localized surfaced plasmons). When LSPs are bound to the surface of the metal nano-structure, it creates a plasmonic structure, which can enhance the signal of the phosphores more than 100 times.
