(A) Schematic of the partition experiment to determine the degree of coumarin 17 leaching in the presence of 1-octanol, a cell-membrane mimic. (B) Normalized fluorescence at 500 nm of the 1-octanol layer representing the percentage of leached coumarin 17. Fluorescence was normalized to a free control of 17 dissolved in 1-octanol. Bars represent the average of three independent samples, and error bars represent the standard deviation of three independent samples.
