چکیده انگلیسی
Theranostic agents are attracting a great deal of attention in personalized medicine. Here, we developed a protein-based, facile method for fabrication of nanosized, reduced graphene oxide (nano-rGO) with high stability and low cytotoxicity. We constructed highly integrated photoacoustic/ultrasonic dual-modality imaging and photothermal therapy platforms, and further demonstrated that the prepared nano-rGO can be used as ready-to-use theranostic agents for both photoacoustic imaging and photothermal therapy without further surface modification. Intravenous administration of nano-rGO in tumor-bearing mice showed rapid and significant photoacoustic signal enhancement in the tumor region, indicating its excellence for passive targeting and photoacoustic imaging. Meanwhile, using a continuous-wave near-infrared laser, cancer cells in vivo were efficiently ablated, due to the photothermal effect of nano-rGO. The results suggest that the nano-rGO with protein-assisted fabrication was well suited for photoacoustic imaging and photothermal therapy of tumor, which is promising for theranostic nanomedicine.
