Nowadays, cancer photothermal therapy (PTT) with near-infrared light and photoabsorbers has garnered extensive research interests owing to its minimal invasiveness compared with conventional cancer interventions.Imaging guided tumor ablation has been extensively applied in both biomedical research and clinical trials as one of the most exciting and challenging strategies for cancer treatment.Imaging with contrast agent allows noninvasive diagnosis of the disease and real-time monitoring of the particle localization.
