It has also been suggested they could constitute a hitherto unseen hazard. Numerous experimental studies in the field are taking place. We consider that the nature of the interactions allows a more fundamental theoretical framework to be developed. In particular, we describe the intimate link that develops between nanoparticle uptake and cell population evolution. Explicit analytical results are given and the theory compared to experimental observations.enMolecule-cell interactionsTargeted drug deliveryCell population evolutionNanoparticle-cell interactionsJournal Article10133800710.1209/0295-5075/101/380072013-08-21https://creativecommons.org/licenses/by-nc-nd/3.0/ie/
