Abstract

Nanoparticles (NPs) possess unique properties useful for designing specific functionalities for biomedical applications. A prerequisite of a safe-by-design and effective use in any biomedical application is to study NP–cell interactions to gain a better understanding of cellular consequences upon exposure. Cellular uptake of NPs results mainly in the localization of NPs in the complex environment of lysosomes, a compartment which can be mimicked by artificial lysosomal fluid. In this work we showed the applicability of lysosomal fluid as a platform for a fast assessment of gold, iron oxide and silica NP stability over 24 h in a relevant biological fluid, by using multiple analytical methods.
