Abstract

Tissue-simulating phantoms are widely used for controlled studies of photon transport in turbid media. Here, we describe how polystyrene microspheres, which are often used to simulate optical scattering in such phantoms, can reduce fluorophore quantum yield via collisional quenching. We report studies on UV-visible (fluorescein-based) and NIR (IR125-based) phantoms with differing fluorophore and scatterer concentrations, as well as differing microsphere sizes. Results consistent with the Stern-Volmer relation suggest that the fluorophore intrinsic excited-state lifetime decreased due to collisional quenching from polystyrene microspheres and that the quenching efficiency was dependent on the concentration ratio of fluorophores to microspheres. Lifetime decreases ranging from 10–35% (20%) were measured for fluorescein-based (IR 125-based) phantoms. Since polystyrene microspheres are commonly used in tissue-simulating phantoms for quantitative studies of fluorescence light propagation, their quenching effects on fluorescence intensities may be difficult to separate from intensity losses attributed to optical absorption and scattering in the phantom unless fluorescence lifetime measurements are performed simultaneously.

(a) Measured variation in fluorophore lifetime τ (relative to the intrinsic lifetime τ0) at fixed fluorescein concentration of 8 μM plotted vs. varying volume fractions of polystyrene microspheres, for three different sizes of the microspheres. (b) Same data as in (a), but now plotted vs. σ, the available surface area presented by the microspheres per unit ml of phantom media.

Fig. 4.
Fig. 4.

Measured variation in fluorophore lifetime τ (relative to the intrinsic lifetime τ0) plotted vs. σ, the available surface area presented by the polystyrene microspheres per unit ml of phantom media, for two phantom series at different fluorophore concentrations: series A (40 μM fluorescein, triangles) and series D (8 μM fluorescein, circles). Both phantom series contained 2.0 μm diameter microspheres. For the highest microsphere concentration, phantom series A showed a 20% decrease in measured lifetime, while series D showed up to a 30% decrease for the same microsphere concentration.

Measured variation in fluorophore lifetime τ (relative to the intrinsic lifetime τ0) plotted vs. σ, the available surface area presented by the polystyrene microspheres per unit ml of phantom media, for two phantom series at different fluorophore concentrations: series H (10 μM IR-125, triangles) and series G (1 μM IR-125, circles). Both phantom series contained 2.0 μm diameter microspheres. These data for IR-125 reveal the same quenching behavior vs. fluorophore concentration as data in Fig. 4 for fluorescein.
