Although graphene oxide (GO) has recently been considered as a highly attractive nanomaterial for future cancer imaging and therapy, it is still a major challenge to improve its invivo tumor active targeting efficiency. Here in this full article, we demonstrated the successful and significantly enhanced invivo tumor vasculature targeting efficacy of well-functionalized GO nanoconjugates by using vascular endothelial growth factor 121 (VEGF121) as the targeting ligand. As-developed GO nanoconjugate exhibits excellent invivo stability, specific invitro and invivo vascular endothelial growth factor receptor (VEGFR) targeting, significantly enhanced tumor accumulation (>8 %ID/g) as well as high tumor-to-muscle contrast, showing great potential for future tumor targeted imaging and therapy.
