Tracking metal enhanced fluorescence from Eschericcia coli nano-bio-assemblies within colloidal dispersions by static and 3D spectra emissions

Microscopic Perspective of Synergy between Localized Surface Plasmon Resonance and Disruption of Dye Aggregates in Metal Nanoparticle-Enhanced Fluorescence

“…The consequent increase in the radiative rate constant of the fluorophore is manifested in the hallmark of MEF: an enhancement in fluorescence quantum yield, accompanied by a decrease in fluorescence lifetime . Even though the phenomenon has been known for decades, it has attracted significant recent interest due to its immense potential in diagnostics, biosensing, , optical sensing, and device fabrication with plasmonic metamaterials. − Such applications warrant the design of effective substrates, , development of new molecular plasmonics with metamaterials, insights into the mechanism of MEF, and synthesis of size- and shape-tunable plasmonic NPs. , In this context, there has been intense activity involving NPs of different shapes: spheres, rods, stars, triangles, etc . The separation between fluorophores and the surface of the plasmonic nanostructure surface is also crucial, with typical optimum values in the range of 5–90 nm. − The field is not limited to organic fluorophores.…”
