Bimetallic gold nanorods with enhanced biocorona formation for doxorubicin loading and sustained release.The biomedical applicability of gold nanorods (AuNRs) arises due to their interesting optical and photothermal properties, which can result in the formation of a protein corona layer when exposed to the physiological system.  Furthermore, a significant decrease in the cytotoxicity of protein-coronated bimetallic AuNRs as compared to monometallic AuNRs was also observed.
