Persistent luminescence phosphors (PLPs) can remain luminescent after excitation ceases and have been widely explored in bioimaging therapy since 2007. In bioimaging, PLPs efficiently avoid tissue autofluorescence light scattering interference by collecting persistent signals the end of excitation. Outstanding signal-to-background ratios, high sensitivity, resolution achieved with PLPs. therapy, continuously produce therapeutic molecules such as reactive oxygen species removing sources, which realizes sustained activity a single dose stimulation. However, most are activated ultraviolet or visible light, makes it difficult to reactivate vivo, particularly deep tissues. recent years, sources penetration activate PLPs, including X-ray, γ-ray, ultrasound. Researchers found that various inorganic organic be ultrasound, making these valuable imaging deep-seated tumors. These X-ray/γ-ray/ultrasound-activated not systematically introduced previous reviews. this review, we summarize recently developed ultrasound luminescence. The biomedical applications deep-tissue also discussed. This review provide instructions for design deep-tissue-renewable further promote phototheranostics, noninvasive biosensing devices, energy harvesting.

The development of phototherapeutics with high photothermal conversion efficiency (PCE) and strong ability to generate reactive oxygen species under single near-infrared (NIR) laser irradiation for immuno-phototherapy applications remains a significant challenge. Herein, we optimally selected the molecule IT-4F an acceptor-donor-acceptor (A-D-A) structure prepare water-dispersible nanoparticles (NPs) by assembly DSPE-PEG-NH₂. Such NPs have NIR absorption fluorescence peaks at 728 817 nm, respectively. They can singlet (¹O₂) superoxide anion (O₂^-·) irradiation, ¹O₂ generation quantum yield 31.5%. also effectively convert photon-energy into heat PCE 42.8%. outstanding properties enable them be used in imaging guided therapy (PTT), photodynamic (PDT). Moreover, PDT PTT triggered immunogenic cell death PANoptosis tumor cells, which not only inhibited growth metastasis mice model, but induced robust immune response, evidenced increased infiltration CD8⁺ T CD4⁺ dendritic decreased presence immunosuppressive cells such as myeloid-derived suppressor regulatory cells. efficacy organoid human breast cancer was verified.

The advent of autonomous nanomotors presents exciting opportunities for nanodrug delivery. However, significant potential remains enhancing the asymmetry and advancing development second near-infrared (NIR-II) light-propelled capable operating within deep tissues. Herein, we developed a dual-ligand assisted anisotropic assembly strategy that enables precise regulation interfacial energy between selenium (Se) nanoparticle periodic mesoporous organosilica (PMO). This facilitates controllable growth PMO on Se nanoparticle, leading to formation Se&PMO Janus nanohybrids. exposure ratio subunit nanohybrids can be finely tuned from 0% 75%. Leveraging transformability subunit, variety functional MxSe&PMO nanocomposites (MxSe denotes metal selenide) were further derived. As proof concept, CuSe&PMO nanohybrids, with NIR-II photothermal properties, employed as light-driven nanomotors. By precisely controlling CuSe nanostructure, these achieved optimal self-propulsion, thus cellular uptake promoting tumor penetration. Furthermore, high loading capacity hydrophobic framework enabled incorporation disulfiram, thereby significantly boosting efficacy synergistic active-motion therapy.

Abstract Organic semiconducting small molecules that simultaneously possess NIR‐IIb (1500–1700 nm) fluorescence imaging (FLI), hypoxia‐tolerant photodynamic therapy (PDT) as well photothermal (PTT) abilities activated by a single NIR‐II (1000‐1700 light can achieve high‐performance deep‐tissue phototheranostics, but have not gain much attention. Herein, novel organic molecule (DTT) with an absorption maximum at 844 nm and emission 944 in its monomer state is synthesized through delicate molecular design. Surprisingly, the spectrum of DTT extend into region. Subsequently, phototheranostic nanoparticles (DTT NPs) dramatically red‐shifted absorption/emission peak (1029/1128 are skillfully developed based on J ‐aggregation strategy, which show greatly high molar absorptivity Upon 1064 excitation, resolution FLI be achieved whole‐body vessels, cerebral vasculatures, tumors living mice treated NPs. Moreover, NPs also produce type‐I reactive oxygen species hyperthermia under laser irradiation for oxygen‐less‐dependent PDT PTT combination therapy, eventually achieving efficient antitumor effects. This work provides facile strategy designing high‐efficiency phototheranostics.
