However, a short half-life is still a hurdle for the translation of ferritin-based nanomedicines into the clinic. Here, we developed a series of rationally designed long circulating ferritin nanocages (LCFNs) with 'Intrinsically Disordered Proteins (IDP)' as a stealth layer for extending the half-life of ferritin nanocages. Through predictions with 3D modelling, the LCFNs were designed, generated and their pharmacokinetic parameters including half-life, clearance rate, mean residence time, and more, were evaluated by qualitative and quantitative analysis. LCFNs have a tenfold increased half-life and overall improved pharmacokinetic parameters compared to wild-type ferritin nanocages (wtFN), corresponding to the low binding against bone marrow-derived macrophages (BMDMs) and endothelial cells. Subsequently, a tumor targeting moiety, epidermal growth factor receptor (EGFR)-targeting affibody peptide, was fused to LCFNs for evaluating their potential as a theragnostic platform. The tumor targeting-LCFNs successfully accumulated to the tumor tissue, by efficient targeting via active and passive properties, and also the shielding effect of IDP in vivo. This strategy can be applied to other protein-based nanocages for further progressing their use in the field of nanomedicine.
