We have studied the effect of highly fluorescent gold nanoclusters (Au NCs) (∅ < 3 nm) stabilized by different ligands on the intracellular accumulation and immune response of human derived-monocyte dendritic cells (DCs). Results indicate that the high uptake efficiency of Au NCs is strongly related to their small size and to the nature of the ligand, with zwitterionic ligands being more effective...
Nanoparticles (NPs) have been suggested for immunotherapy applications in order to optimize the delivery of immuno-stimulative or -suppressive molecules. However, low attention towards the impact of the NPs' physicochemical properties has presented a major hurdle for developing efficient immunotherapeutic agents. Here, the effects of porous silicon (PSi) NPs with different surface chemistries were...
