“…The utilizations of other inorganic nanoagents for PA imaging–guided NIR‐II PTT has also been reported. For example, black hollow silicon oxide NPs (HSiOx–PEG NPs) with a wide absorption from ultraviolet (UV) to NIR‐II region was developed by Li and co‐workers . After 15 min of intratumoral injection of HSiOx–PEG NPs, the PA intensity at 900 nm in tumor regions increased by 23.1‐fold.…”

Photoacoustic (PA) imaging and photothermal therapy (PTT) provide useful tools for diagnosis and treatments of diseases. However, current applications of PA imaging and PTT are greatly limited by their relying on light source in the first near‐infrared (NIR) window (NIR‐I, 750–1000 nm), which shows shallow tissue penetration depth. Recently, this predicament is addressed by the use of second NIR (NIR‐II) light ranging from 1000 to 1700 nm due to reduced light–tissue interaction and increased allowable power density for light irradiation. Since a few endogenous biomolecules can absorb or emit NIR‐II light, it is necessary to develop contrast and therapeutic agents used for PA imaging and PTT in the NIR‐II window. This review summarizes the recent progresses of NIR‐II absorbing optical agents for PA imaging and PTT in living animal models. The prominent performance of NIR‐II PA imaging and NIR‐II PTT is first introduced with the use of optical agents, followed by discussion of the applications of NIR‐II PTT under the guidance of NIR‐I or NIR‐II PA imaging. At last, challenges and perspectives of NIR‐II absorbing optical agents for PA imaging and PTT are proposed.

“…The use of multifunctional nanoagents with multimodal imaging and synergistic therapeutic properties for cancer theranostics is a rising trend in nanomedicine . Considering that the activation of X‐PDT involves the use of X‐rays, a synchronous radiotherapy (RT) can be used to enhance treatment effects, as long as the nanoscintillators contain elements of high nuclear charge (high‐ Z ), which are well known to have radiosensitization properties .…”

The use of X-rays instead of UV/Vis light to trigger photodynamic therapy, named X-rayinducible photodynamic therapy, holds tremendous promise due to ah igh penetration capacity in tissues and is worthy of in-depth study.Inthis study, anovel multifunctional nanoagent based on Merocyanine 540coupled Gd 2 (WO 4 ) 3 :Tb nanoscintillators and the vitalization of its abilities for dual-modal computed tomography and the magnetic-resonance-imaging-guided synergistic radio-/X-ray inducible photodynamic therapyoftumors is reported. Synergistic therapies showahigher tumor growth inhibition efficiency at al ower X-ray dose than radiotherapya lone. Through this proof-of-concept work, away to tactfully understand and utilize nanoscintillators for cancer theranostics is shown.
