Summary

자동 번역

Dit artikel beschrijft methoden voor de synthese en TL-etikettering van nanodeeltjes (NP). De NP's werden toegepast in pulse-chase experimenten om de endo-lysosomale systeem van eukaryotische cellen te labelen. Manipulatie van de endo-lysosomale systeem door de activiteiten van de intracellulaire pathogeen Salmonella enterica werden gevolgd door live cell imaging en gekwantificeerd.
