Figure 1: A. Co-localization of NLC-Coumarin 6 NPs and mCherry-labeled F.n.o. The imaging was performed in zebra-fish embryos 3-4 hours postinfection/ 1-2 hours after the injection of the NLC NPs. The bulk of the bacterial burden and the NPs were localized to macrophages. B. Co-localization of PLGA-Coumarin 6 NPs and mCherry-labeled F.n.o. The imaging was performed in zebra-fish embryos 3-4 hours post-infection/ 1-2 hours after the injection of the PLGA NPs. The bulk of the bacterial burden and the NPs were localized to macrophages. Scale bar: 10 μm.
