Calculated Enhancement Factor for Labeled Avidin

Probe	$G_{\text{fl}}^{(1)}$	$G_{\text{fl}}^{(2)}$	Gexc	Γ (ns−1)a	Γm(ns−1)a	Nr
Pacific Blue	28	235	25	0.32	11b	35
Lissamine	16	200c	9.5c	0.53	23b	45
Texas Red	46	200c	418c	0.16	71b	455

^aCalculated using Γ = Q/〈τ〉.

^bCalculated assuming the quantum yield =1.0 on the silver island films.

^cCalculated assuming two-photon excitation displays a 200-fold increase in probe fluorescence on the silver island films.
