| Summary: | 碩士 === 國立成功大學 === 化學系 === 104 === In this study, we provide a strategy of the metal ion-ligand coordination feature for the hydrophilic hollow nanostructures showing the capability of gas release to fulfill the echogenicity for the ultrasound imaging. We began with solid Cu2O nanoparticles, followed by a modified Kirkendall process to convert solid Cu2O into hollow porous CuS. The ferric ion (Fe3+) was used as the coordination center to bridge both dopamine and bicarbonate. The dopamine served as the bidentate ligand to coordinate Fe3+, while the bicarbonate coordinated to Fe3+ in a monodentate manner. The coordinated CuS nanoparticles revealing NIR light-induced hyperthermia resulted in the decomposition of bicarbonate into CO2 serving as echogenic source and the performance in inhibition of the tumor growth.
