Abstract ：
Real-time evaluation of the Fenton reactivity of chemodynamic therapy (CDT) agents is critical for developing effective CDT agents. However, the development of CDT agents capable of self-evaluating Fenton reactivity remains challenging. Herein, using OH as an indicator of Fenton reaction, we report a CDT nanoplatform, DCNP@FM-Fe2+-PEG (DFFP), which integrates a OH-activatable NIR-II ratiometric fluorescent nanoprobe and a Fenton agent (Fe2+), for self-evaluating Fenton reactivity. DFFP can induce cell apoptosis by converting intracellular H2O2 into OH and depleting GSH. In the presence of OH, NIR-II fluorescence signal of DFFP at 1050 nm under 808 nm excitation (F 1050Em,808Ex) would be enhanced, while its fluorescence signal at 1550 nm under 980 nm excitation (F 1550Em,980Ex) remained stable. DFFP was able to self-evaluate its Fenton reactivity by OH-activatable F 1050Em,808Ex/F 1550Em,980Ex signal, and it exhibited excellent anticancer effect. This strategy provides a new approach to construct CDT agents capable of self-evaluating the Fenton reactivity in real time.

Abstract ：
In the field of quantum dot (QD)-based micro-light-emitting diode (mu LED) full-color display technology, achieving high color conversion efficiency (CCE) is one of the key performance indicators. In this work, a mu LED architecture is presented that incorporates an optimized nanorod array, with QDs and nanogapped gold nanoparticles (AuNNPs) embedded in the inter-rod gaps. By harnessing non-radiative energy transfer (NRET) and localized surface plasmon resonance (LSPR), the absorption and utilization of quantum well (QW) energy by the QDs are significantly enhanced. To ensure efficient current spreading and uniform light emission, graphene is employed as a transparent conductive layer to interconnect the nanorods. As graphene can transfer photogenerated carriers to the QDs, enhancing their quantum yield, it is also introduced as an intermediate insertion layer and support layer, allowing the integration of a second layer of QDs and AuNNPs on the light-emitting surface. This design maintains the electrical performance of the nanorod mu LED while achieving ultra-high CCE. Experimental results demonstrate that the proposed mu LED with nanorod structures and AuNNPs achieves a maximum CCE of 94%, representing a 102% improvement compared to conventional planar mu LEDs. These findings offer promising insights for advancing high-performance, full-color mu LED display technologies through nanoscale engineering.

Abstract ：
The hypoxic microenvironment and radioresistance of tumor cells, as well as the delay in efficacy evaluation, significantly limit the effect of clinical radiotherapy. Therefore, developing effective radiosensitizers with monitoring of tumor response is of great significance for precise radiotherapy. Herein, a novel radiosensitizer (term as: SCuFs) is developed, consisting of traditional Chinese medicine (TCM) compounds salidroside, Cu2+, and hydroxyl radical (center dot OH) activated second near-infrared window fluorescence (NIR-II FL) molecules, which make the radiosensitization effect and boosted chemodynamic therapy (CDT) efficacy. The overexpressed glutathione in the tumor induces the SCuFs dissociation, allowing deep penetration of the drug to the whole tumor region. After X-ray irradiation, salidroside inhibits the Nuclear factor erythroid 2-like 2 (Nrf2)protein expression and blocks cells in the G2/M phase with the highest radiosensitivity, which amplifies the reactive oxygen species (ROS) generation to exacerbate DNA damage, thus achieving radiosensitization. Meanwhile, the upregulated ROS provides sufficient chemical fuel for Cu+-mediated CDT to produce more center dot OH. NIR-II FL imaging can monitor the center dot OH changes during the therapy process, confirming the radiosensitization effect and CDT process related to center dot OH. This study not only achieves effective radiosensitization and cascaded ROS-mediated CDT efficacy, but also provides a useful tool for monitoring therapeutic efficacy, showing great prospects for clinical application.

Abstract ：
Traditional responsive fluorescent probes are predominantly restricted to qualitative biomarker detection, incapable of delivering real-time quantitative analysis or spatial mapping of protease activity in vivo, which is essential for elucidating disease progression. To overcome this, a ratiometric second near-infrared region (NIR-II) fluorescent (FL) probe (DCNP@IR-806) was developed by conjugating caspase-3-specific peptide substrates and sensitizer molecules (IR-806) to lanthanide-doped down-conversion nanoparticles (DCNP). DCNP@IR-806 achieves single-channel emission at 1550 nm under dual excitation, facilitating self-calibrated quantification and real-time monitoring of activated caspase-3 in vivo. Radiotherapy induces tumor cell apoptosis, thereby activating caspase-3, which subsequently triggers a ratiometric NIR-II FL signal change of DCNP@IR-806. The ratiometric signal demonstrates a linear correlation with caspase-3 concentration, achieving a detection limit of 9.96 U mL-1. Then, an early efficacy assessment system capable of predicting radiotherapy outcomes within 12 h post-treatment was constructed, markedly expediting evaluation compared to traditional methods that require weeks. This rapid, precise, and user-friendly assessment facilitates timely optimization of therapeutic regimens to enhance efficacy while minimizing side effects. This platform represents a significant advancement in precision oncology by transitioning from qualitative imaging to in situ quantitative biomarker tracking.

Abstract ：
Chemiluminescence (CL) is a self-illuminating phenomenon fueled by chemical energy instead of extra excited light, which features superiority in sensitivity, signal-to-background ratios, and imaging depth. Strategies to synthesize a CL emission unimolecular skeleton in the second near-infrared window (NIR-II) and a unimolecular probe with direct duplex NIR-II [CL/fluorescence (FL)] emission are lacking. Here, we employ modular synthesis routes to construct a series of directly activated NIR-II CL emission unimolecular probes with a maximum emission wavelength of up to 1060 nm, and use them for real-time and continuous detection of the superoxide anion generated in acetaminophen induced liver injury in a female mice model under both NIR-II CL and NIR-II FL imaging channels. Thus, this study establishes a directly activatable NIR-II CL emission unimolecular skeleton, validating the scalability of this duplex NIR-II CL/FL imaging platform in bioactive molecule detection and disease diagnosis.

Abstract ：
Large osseous void, postsurgical neoplastic recurrence, and slow bone-cartilage repair rate raise an imperative need to develop functional scaffold in clinical osteosarcoma treatment. Herein, a bionic bilayer scaffold constituting croconaine dye-polyethylene glycol@sodium alginate hydrogel and poly(L-lactide)/hydroxyapatite polymer matrix is fabricated to simultaneously achieve a highly efficient killing of osteosarcoma and an accelerated osteochondral regeneration. First, biomimetic osteochondral structure along with adequate interfacial interaction of the bilayer scaffold provide a structural reinforcement for transverse osseointegration and osteochondral regeneration, as evidenced by upregulated specific expressions of collagen type-I, osteopontin, and runt-related transcription factor 2. Meanwhile, thermal ablation of the synthesized nanoparticles and mitochondrial dysfunction caused by continuously released hydroxyapatite induce residual tumor necrosis synergistically. To validate the capabilities of inhibiting tumor growth and promoting osteochondral regeneration of our proposed scaffold, a novel orthotopic osteosarcoma model simulating clinical treatment scenarios of bone tumors is established on rats. Based on amounts of in vitro and in vivo results, an effective killing of osteosarcoma and a suitable osteal-microenvironment modulation of such bionic bilayer composite scaffold are achieved, which provides insightful implications for photonic hyperthermia therapy against osteosarcoma and following osseous tissue regeneration.

Abstract ：
The external quantum efficiency (EQE) enhancement of different sized GaN micro-light-emitting diodes (mu LEDs) by using localized surface plasmons (LSPs) have been studied. Silver nanoparticles (Ag NPs) are attached to the sidewalls of mu LEDs by spin-coating so as to be effectively coupled with the multiple quantum well (MQW) of mu LEDs and generate the LSPs. In the mu LEDs with 20 x 20 mu m2 large mesas, the LSPs can effectively inhibit the efficiency droop. Compared to the mu LED samples without the LSPs coupling, the EQE has been enhanced by about 8% at a high current density of 20,000 A/cm2. This work confirms the effectiveness of the LSPs technology in improving the mu LED performances, which is originally practiced only on the basal faces of conventional LEDs.

Abstract ：
Stimuli-triggered release and alleviating resistance of iridium(III)-based drugs at tumor sites remains challengeable for clinical hepatoma therapy. Herein, a doxorubicin@iridium-transferrin (DOX@IrTF) nanovesicle was synthesized by carboxylated-transferrin (TF) and doxorubicin-loaded amphiphilic iridium-amino with quaternary ammonium (QA) groups and disulfide bonds. The QA groups enhanced photophysical properties and broadened production capacity of photoinduced-reactive oxygen species (ROS), while the disulfide-bridged bonds regulated oxidative stress levels through reacting with glutathione (GSH); simultaneously, modification of TF improved recognition and endocytosis of the nanovesicle for tumor cells. Based on in -vitro results, a controlled-release behavior of DOX upon a dualresponsiveness of GSH and near-infrared ray (NIR) irradiation was presented, along with high-efficiency generation of ROS. After an intravenous injection, the nanovesicle was targeted at tumor sites, realizing TF-navigated photoacoustic imaging guidance and synergistic chemotherapy-photodynamic therapy under NIR/GSH stimulations. Overall, newly-synthesized DOX@Ir-TF nanovesicle provided a potential in subcutaneous hepatocellular carcinoma therapy due to integrations of targeting delivery, dual -stimuli responsive release, synergistic therapy strategy, and real -time monitoring.

Abstract ：
The controllable assembly of nanoparticles significantly improves their biological effects in vivo. However, it is difficult to realize the assembly regulation of nanomaterials under complex physiological conditions. Herein, endogenous glutathione (GSH)-triggered vesicles with spatiotemporally confined aggregation of gold nanogapped nanoparticles (AuNNPs) within vesicles were developed. These vesicles had excellent photoacoustic (PA) imaging capability in the near-infrared second window (NIR-II) for precise localization of deep tumors, measuring tumor volume, and making deep tumors more sensitive to radiotherapy and chemodynamic therapy (CDT). The vesicles were prepared via self-assembly of MnO2-coated AuNNPs that were functionalized by phosphate-polystyrene and bovine serum albumin (AuNNP@MnO2 Ve@BSA). The MnO2 shell was etched when AuNNP@MnO2 Ve@BSA vesicle was exposed to GSH, the gap between intra-vesicular AuNNP@MnO2 NPs was reduced. This significantly enhanced the plasmonic coupling effect be-tween AuNNP@MnO2 NPs, giving it excellent NIR-II PA imaging capability, and thus can be used to delineate the boundary and volume of deep-seated tumors. Meanwhile, the Mn2+-mediated CDT released after the etching of the MnO2 shell interacted with GSH-responsive AuNNP@MnO2 Ve@BSA and significantly in-hibited tumor growth due to enhanced radiosensitization effect. This unique strategy provides new per-spectives and methods for designing and applying biomedical nanomaterials.& COPY; 2023 Published by Elsevier Ltd.
