Summary

Automatic Translation

I denne artikel beskrives metoder til syntese og fluorescerende mærkning af nanopartikler (NP'er). NPS blev anvendt i puls-chase forsøg at mærke endo-lysosomale system eukaryote celler. Manipulation af endo-lysosomale system ved aktiviteter af den intracellulære patogen Salmonella enterica blev fulgt af levende celler og kvantificeret.
