Representative inorganic photosensitizer-based LTNs. (A) Schematic illustration and TEM image of gold-silica quantum rattles. The 2 nm sized gold quantum dots were stabilized in mesoporous silica-based nanoshells. Adapted with permission from 124. (B) Preparation of plasmonic vesicles from ultrasmall gold nanorods that could dissociate to give PEG-coated gold nanorods after the degradation of PLGA. Adapted with permission from 137. (C) PVP stabilized 64Cu-labeled CuS nanodots with ultrahigh efficient renal clearance as evidenced by time-resolved PET. Adapted with permission from 144. (D) The use of SWCNTs in the treatment of 4T1 lung metastases. The intratumorally-injected SWCNTs could accumulate in SLNs which together with the primary tumor must be irradiated with a laser to prevent the lung metastasis of the 4T1 tumor and prolong the survival of the animals.
