Gd2O3/b-TiO2 composite nanoprobes with ultra-high photoconversion efficiency for MR image-guided NIR-II photothermal therapy
Low photoconversion efficiency and limited tissue penetration are the major barriers for photothermal therapy (PTT) agent application. Here, an efficient organic/inorganic dual-PTT agent guided by MRI was proposed. It is proved the oxygen vacancy band narrowed its band gap that led to NIR-II region absorb. Furthermore, the defect energy level trapping carrier and conjugate synergistic …
