Figure 4.

(A) The distance dependence of a fluorophore in the vicinity of a metal nanoparticle on the resulting fluorescence rate is shown. The solid and dotted data are from theoretical and experimental outcomes, respectively; (B) The fluorescence image is acquired from a single fluorophore molecule located at 2 nm away from the metal. The dip in the center is due to fluorescence quenching; (C) Corresponding theoretical image for (B) is provided. Reproduced with permission from Ref. [76] Copyright (2006) American Physical Society.
