Light incident on metal NPs induces strong electromagnetic fields in the proximity of the NP surfaces. This unique property of metal NPs, known as localized surface plasmon resonance, enables the control on the excitation and relaxation processes of given fluorophores, which could strongly enhance or quench the fluorescence intensity. Since the near-field interactions between metal NPs and fluorophores are inherently interconnected with their nanoscale organization, we utilized the self-segregating property of block copolymer micelles to organize the spatial location of fluorophore in the vicinity of metal NPs. By analyzing steady-state and time-resolved fluorescence, we discuss the strong correlation of micellar structures with surface-plasmon-coupled fluorescence with an emphasis on the strategy for fluorescence enhancement. |
