(A) Schematic of loading IR-140 into HMSNs. (B) Washing conditions facilitate J-aggregation. 10 mg/mL HMSNs were combined with 10 mM IR-140 in DMSO and washed with PBS with (green) and without (dark blue) sonication. Prewash spectrum, diluted 1:350 is shown in orange. Loading control for solid, nonporous Stöber spheres is shown in gray. (C,D) TEM images of HMSNs with (D) and without (C) IR-140 treatment.
