  • Liver tumor-targeting ultrasound contrast agent and method for preparing the same
    Patent number: 9259493
    Abstract: Disclosed is a liver tumor-targeting ultrasound contrast agent. The ultrasound contrast agent includes a gas-generating core and a hyaluronic acid shell. The ultrasound contrast agent can be specifically delivered to liver cells. This specific delivery enables easy differentiation between normal liver cells and liver tumor cells by ultrasound imaging. In addition, the ultrasound contrast agent is highly stable in aqueous condition and causes no cytotoxicity. Also disclosed is a method for preparing the ultrasound contrast agent.
    Type: Grant

  • TUMOR-TARGETING GAS-GENERATING NANOPARTICLE, METHOD FOR PREPARING THE SAME, AND TUMOR-TARGETING NANOPARTICLE FOR DRUG DELIVERY USING THE SAME
    Publication number: 20130323177
    Abstract: A tumor-targeting gas-generating nanoparticle, a method for preparing same and a tumor-targeting nanoparticle for drug delivery using same relate to a tumor-targeting gas-generating nanoparticle including a polycarbonate core and a amphiphilic coat, a method for preparing same and a tumor-targeting nanoparticle for drug delivery using same. Since a tumor-targeting gas-generating nanoparticle according to the present disclosure is accumulated in the tumor tissue in large quantity and generates strong ultrasound wave signals, it can be usefully used as a contrast agent for ultrasonic imaging.
