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.
