| 英文摘要 | Theranostic microcapsules were successfully fabricated by introducing gold nanoparticles into poly(lactic acid) microcapsules through a double-microemulsion method, followed by depositing graphene oxide onto the microcapsule surface via electrostatic layer-by-layer self-assembly technique. It was proved that the obtained microcapsules could serve as a contrast agent to simultaneously enhance US imaging and X-ray CT imaging greatly both in vitro and in vivo. In addition, the in vivo therapeutic examinations showed that the microcapsule was an effective agent for photothermal therapy of cancer. The nearinfrared laser light ablated the tumor completely within 9 days in the presence of the microcapsules and the tumor growth inhibition was 83.8%. The combination of real-time ultrasound with 3-D computed tomography through a single microcapsule agent is very helpful for accurately interpreting the obtained images, identifying the size and location of the tumor, as well as guiding and monitoring the photothermal therapy. Simultaneously, the effectiveness of photothermal therapy could be evaluated by the combined US and CT imaging enhanced by the microcapsule agent. Such a versatile microcapsule system might bring opportunities to the next generation of multimodal imaging guided cancer therapy. Crown Copyright 2013 Published by Elsevier Ltd.
