Tissue distribution of MPEG-PCL micelle-delivered cargo after intravenous (I.v.) or intravesical (I.ves.) application. The drug-associated green fluorescence indicated the deposition of drugs. (A) The fluorescence image of organs from mice 2 hours after intravenous or intravesical application of courmarin-6/MPEG-PCL micelles. (B) Fluorescence images of bladders from mice with intravenous or intravesical application of courmarin-6/MPEG-PCL micelles at different time points.
