Anisotropic plasmonic metals have attracted significant attention in enhancing the catalytic performance of catalysts due to their broad light-harnessing capabilities and active hot electrons; however, limited investigations have been dedicated towards improving their electrochemical reaction performance in the visible and near infrared (NIR) regions. Herein, anisotropic Pt-edged Au nanodisks (NDs) were synthesized by controlling the preferential loading of Pt and used as catalysts for plasmon-enhanced electrochemical methanol oxidation reactions (MORs) under visible-NIR light irradiation by, and the light-enhanced electric current over the Pt-edged Au NDs was found to be 3-fold higher than that under dark conditions. Wavelength-dependent electric current over the Pt-edged Au NDs for the MOR in the visible-NIR light region demonstrates that the light-induced enhancement of the electric current is due to surface plasmon resonance (SPR) of the Au NDs. Furthermore, plasmonic hot electron transfer was studied by the single-particle photoluminescence images and spectra of Au NDs and Pt–Au NDs, and the dipole surface plasmon resonance (DSPR) mode was proved to be the main channel for hot electron transfer. During the electrochemical reaction under visible-NIR light irradiation, a plasmonic hot electron is transferred to the electrode, and a “hot hole” is left on the surface, boosting the MOR.

Narrow bandgap Ag 2 Te quantum dot (QDs) hold great promise in the fields of bioimaging, chemo-/bio-detection, and thermoelectric materials, but their biosafety has not been well estimated yet. In this study, we studied the biodistribution and toxicity of polyethylene glycol–coated Ag 2 Te QDs (Ag 2 Te QDs-PEG) in mice after a single intravenous injection. After entering the mice, Ag 2 Te QDs-PEG displayed a short circulation time in the blood (half-life was less than 2 h), and mainly accumulated in the liver and spleen. The stability of Ag 2 Te QDs-PEG in the mice depended on accumulation organ and time. Ag 2 Te QDs-PEG were stable in the spleen within 28 days but decomposed in the liver after 7 days. The decomposed Ag 2 Te QDs-PEG were eliminated from the body via different routes, as Ag was detected only in feces while Te was found only in urine. Meanwhile, Ag 2 Te QDs-PEG did not show obvious adverse effects on the body weights, organ indices, biochemical parameters, the levels of essential metal Cu and Zn in organs, and organ pathological investigations during 28 days. In addition, the important effects of anion to the fates of silver chalcogenide QDs in vivo was demonstrated by comparing the distributions of the Ag 2 Te QDs and other two silver chalcogenide QDs (Ag 2 S and Ag 2 Se). Our findings indicate Ag 2 Te QDs have good biocompatibility in mice, which is a guarantee for their safe applications in the future.

The second near-infrared window (NIR-II, 1000-1700 nm) phosphor-converted LEDs (pc-LEDs) show great potential for portable spectroscopic detection. However, high-performance long-wavelength (>1350 nm) NIR-II phosphors that combine broadband emission, high thermal stability, and efficient blue-light excitation, are still relatively scarce. Herein, a Lu 3 Ga 5 O 12 :Cr 3+ ,Ni 2+ phosphor was developed via a Cr 3+ sensitization strategy. Cr 3+ and Ni 2+ stably occupy the [GaO 6 ] octahedral sites, enabling efficient energy-transfer from Cr 3+ to Ni 2+ . The optimal sample exhibits broadband NIR-II emission at 1427 nm with an FWHM of 277 nm, an EQE of 23.1%, and excellent thermal stability (I 373K /I 293K = 81.5%). The pc-LED based on this NIR-II phosphor achieves penetration imaging and non-destructive identification of daily necessities. More notably, rapid spectral differentiation of common plastics (PA, PE, PP, PVC and PET) was successfully realized using the NIR-II luminescence of the as-prepared phosphor. This work provides guidance for constructing high-performance NIR-II phosphors and promotes the practical deployment of NIR spectroscopy in resource recycling.

Triple-negative breast cancer (TNBC) is one of the most aggressive breast cancer subtypes with high metastatic and recurrence rates. However there is still a lack of effective targeting nanoprobes (NPs) which is leading to suboptimal targeted therapy. Cell membrane-encapsulation methods are one of the ideal targeting strategy, which could enhance the biocompatibility through endogenous membrane components while enabling functional integration of targeting and imaging capabilities. In this study, fluorescent dye-clinical indocyanine green (ICG) was successfully encapsulated by TNBC cell membranes via dual biolayer method to form M-ICG NPs. The M-ICG NPs exhibited well cellular uptake for TNBC tumor cells via active targeting capability after homologous cancer cell membrane coating. Meanwhile, strong near-infrared (NIR) fluorescence signals were detected at the tumor sites from mice post-injection of M-ICG NPs at 24 h, indicating that their effective targeted tumor accumulation enables good tumor-specific labeling with strong NIR fluorescence emission. Furthermore, the M-ICG NPs retain the excellent optical and photothermal properties of ICG. Under 808 nm laser irradiation, via infrared imaging, the process of temperature monitoring up to 55°C within 12 min was recorded, exhibiting a strong photothermal effect, which lays a foundation for constructing a multifunctional nanoplatform with tumor-specific targeting, excellent biocompatibility and structural stability.

Luminescent thermometry in the second near-infrared (NIR-II) window holds significant promise for non-invasive. However, its practical application is severely hindered by thermal quenching at elevated temperatures, which limits the development of highly sensitive NIR-II thermometers capable of thermally enhanced emission. Here, we present a rationally designed integer phonon-matching strategy that enables NIR thermal enhancement specifically in singly Er 3+ -doped Ca 2 YNbO 6 double perovskite hosts. Through combined experimental investigations and rate equation modeling, we reveal that efficient multi-phonon relaxation (MPR) between the Er 3+ : 4 I 11/2 and 4 I 13/2 levels is activated when the electronic energy gap corresponds to an integer multiple ( n ≤ 5) of the dominant phonon energy. This resonant phonon-matching condition facilitates highly efficient MPR with increasing temperature, leading to a pronounced 1.66-fold enhancement in the Er 3+ NIR-II emission. Furthermore, we demonstrate the simultaneous occurrence of NIR thermal enhancement and ratiometric temperature sensing in Ca 2 YNbO 6 : Yb 3+ /Er 3+ /Ho 3+ /Pr 3+ crystals, achieving an exceptional relative sensitivity of 0.87% K −1 at 398 K. These findings not only circumvent the thermal quenching limitations of NIR-II phosphors but also establish phonon engineering as a versatile strategy for designing thermally enhanced luminescence, opening new avenues for flexible monitoring of pipeline integrity and organic compound leakage based on differential NIR-II luminescence absorption.

Recurrence of solid tumors after surgical resection is a major barrier to tissue regeneration. As an emerging treatment strategy, photo-thermo-electric therapy ablates tumor cells via photothermal effects and generates reactive oxygen species (ROS) via thermoelectric effects to disrupt heat shock proteins, thereby suppressing their protective function in tumor cells. However, conventional materials suffer from low thermoelectric efficiency and weak tissue penetration ability. In this study, we fabricated iodine-doped bismuth sulfide (I-Bi 2 S 3 ) nanorods with bonding heterostructures to improve thermoelectric performance. The approach employed iodine doping to introduce additional electrons, thereby regulating the band structure of Bi 2 S 3 and exploiting the dual low-energy vibration effect of the heterostructures to reduce thermal conductivity. More importantly, controlling the type of heterostructure modulated the bandgap width, thereby expanding the light absorption range to the higher-penetration near-infrared (NIR)-II region for deep tissue treatment. The I-Bi 2 S 3 nanorods were incorporated into poly- l -lactic acid (PLLA) scaffolds to confer antitumor functionality. According to the results, the bonding heterostructures enhanced the conductivity of Bi 2 S 3 and reduced its thermal conductivity, significantly enhancing thermoelectric efficacy. The heterostructures reduced the bandgap of Bi 2 S 3 from 1.23 to 0.88 eV, enabling optical absorption in the NIR-II region. The ROS tests showed that the PLLA/I-Bi 2 S 3 scaffold exhibited good photothermal effects and ROS generation under 1064-nm laser irradiation. The antitumor efficacy of the PLLA/I-Bi 2 S 3 scaffold reached 84.6% against MG-63 cells, demonstrating its exceptional potential in cancer treatment.

Casein-based nanocarriers have demonstrated significant potential in drug delivery due to their excellent biocompatibility, amphiphilic nature, and pH responsiveness. However, casein-based drug carriers suffer from the problems of single intelligent response and poor controllability of drug release. In this study, casein was combined with hollow copper sulfide (CuS) nanoparticles with near-infrared (NIR) responsiveness through electrostatic self-assembly interaction to generate CuS@casein micelles (CuS@CM) with sustained and pH/NIR dual-responsive drug release properties. The strong negative charge of casein and the hollow structure of CuS ensure a high doxorubicin (DOX) loading efficiency (96.84%) of CuS@CM. Ca 2+ is bound with casein to form inter-casein calcium bridges, thereby providing significant sustained release properties for CuS@CM. The charge inversion property of casein at different pH values and excellent NIR responsiveness of hollow CuS nanoparticles endows CuS@CM with superior pH/NIR dual-responsive drug release performance. In vitro cell viability results demonstrated that the pH/NIR dual-responsiveness of CuS@CM-DOX, as well as its excellent tumor cellular uptake capability, could effectively induce tumor cell death. Overall, this study generates a novel casein-based nanocarrier with sustained and pH/NIR dual-responsive drug delivery properties, which has potential application in the field of tumor-targeted drug delivery.

Diabetic wound infection remains a devastating threat to human health, largely due to bacterial colonization and increased antibiotic resistance during conventional treatments, and alternative therapeutic strategies are thus urgent to improve diabetic wound healing. Herein, we developed a multifaceted nanoplatform (CuO@SiO 2 @NO@Au, CSNA NPs) consisting of a cupric oxide (CuO) core, a mesoporous silicon nanoshell loaded with nitric oxide (NO), and in situ grown ultrasmall Au nanoparticles (NPs) for improved diabetic wound treatment. The results showed that the prepared CSNA NPs exhibited remarkable dual-enzyme mimic activity of glucose oxidase (GOx) and peroxidase (POD), effectively oxidizing glucose to generate gluconic acid, thereby reducing the glucose levels and reversing the acidic wound microenvironment. In addition, the fabricated nanoplatform generated abundant H 2 O 2 , which was converted into highly toxic hydroxyl radical ( · OH), leading to efficient bacterial eradication that was subsequently. Under near-infrared (NIR) light irradiation, the CSNA nanozyme also triggered the release of NO gas and aided in the removal of bacterial biofilms, collectively improving the wound microenvironment. By integrating chemodynamic therapy (CDT), photothermal therapy, and NO gas therapy, this self-activatable NIR- augmented nanozyme provides a promising antimicrobial strategy for diabetic wound treatment.

The combinations of phototherapeutic modalities with chemotherapy represent an innovative antitumor strategy. Herein, we constructed a NIR laser regulated nanoplatform (PTE@TPP-NM(DOX/IR780)) via the self-assembly process of PEG-b-PCL modified with mitochondrial targeting triphenylphosphine (TPP), reactive oxygen species (ROS)-sensitive polymer (PTE), DOX, and IR780. Under 808 nm laser irradiation, IR780 in PTE@TPP-NM(DOX/IR780) generated abundant reactive oxygen species (ROS) and heat for photothermal therapy (PTT) and photodynamic therapy (PDT), while ROS oxidized PTE to release DOX for chemotherapy. The signal 808 nm laser could effectively regulate PTT, PDT, and chemotherapy in real-time, enhancing the synergistic efficacy. PTE@TPP-NM(DOX/IR780) could result in depolarization of the mitochondrial membrane and inhibition of the expression of heat shock proteins to amplify antitumor effect. Enhanced therapeutic effect was demonstrated via in vivo and in vitro experiment. This study provided a promising strategy for the design of multifunctional nanocarriers to address the limitation of combined therapy.

The efficient regulation of sunlight to minimize unnecessary energy exchange through windows plays a vital role in advancing building energy efficiency. However, the inferior stability of cerium-doped tungsten trioxide (CWO) as a near-infrared (NIR) shielding material, combined with the poor mechanical properties of its coatings, poses significant challenges for long-term thermal insulation performance. Here, a hierarchical thermal insulation coating with multifunctional integration has been developed. The inner layer’s excellent NIR shielding performance (94.4%) results in a temperature reduction of 13.6 °C, demonstrating outstanding thermal insulation. Meanwhile, the external layer composed of polysilsesquioxane grafted by carboxylated hexafluoropropylene trimer offers exceptional weather resistance due to the low surface energy. The fluorosilicone coating effectively mitigates oxidation of CWO, as evidenced by the retention of NIR shielding performance even after 30 days of exposure to 60 °C and 90% relative humidity. Furthermore, the coating demonstrates superior anti-graffiti properties and achieves an ultra-high mechanical strength of 0.49 GPa through precise fluorine content modulation. This hierarchical design integrates high hardness, excellent abrasion resistance, anti-graffiti functionality, transparency, and long-term operational durability into a single smart window system, offering a promising solution for reducing building energy consumption.

Integrating photonic crystals (PCs) with hydrogel actuators enables synergistic regulation of actuation behavior and structural color, with promising applications in mechanical engineering and bionics. In this study, a bilayer opal hydrogel was fabricated via a two-step photopolymerization method: a polyacrylamide (PAM) hydrogel layer composited with polystyrene (PS) PCs for stable structural color, and a poly(N-isopropylacrylamide) (PNIPAM) hydrogel layer loaded with gold nanorods (Au NRs) for near-infrared (NIR) light responsiveness. Upon temperature or NIR stimulation, the as-prepared hydrogel exhibited reversible bending-recovery behavior with stable structural color in water, liquid paraffin, and air, driven by unbalanced volume changes between the two layers. It achieved a maximum bending angle of 240° and 220° within 10 min in 45 °C water and liquid paraffin, respectively. Notably, unlike temperature stimulation which induced overall deformation in liquid environments, NIR stimulation endowed the hydrogel with spatially selective local bending, realizing a maximum bending angle of 170° in air. Reflection spectrum analysis revealed environment-dependent spectral shifts: in water, both the bending and recovery processes were accompanied by a red shift (less 16 nm) of the reflection peak, while in liquid paraffin and air, a red shift occurred during bending and a blue shift was observed during recovery. This discrepancy originates from differences in water exchange efficiency between the hydrogel and its surrounding environments. The bilayer opal hydrogel shows great potential in high-performance flexible actuators such as underwater sensors and light-controlled micro-robots. This work also reveals a regulation mechanism of environment-material interactions on the responsiveness of PC-based smart hydrogels, providing theoretical and technical guidance for their applications in complex environments.

Combining information from different images for multispectral image fusion can enhance human or machine perception. Nowadays, various luminescent materials with different spectral responses are used for image fusion, but this requires complex algorithms and systems to address pixel and position mismatches. Using a single luminescent material to obtain multispectral imaging can effectively avoid pixel mismatch and complex imaging processing. Herein, we report efficient blue-light-excitable ultrabroadband white emission and near-infrared (NIR) emission in the Te 4+ /Mo 4+ -codoped Cs 2 ZrCl 6 with a luminous efficiency of 94.2% (NIR region: 52.6%). Moreover, this compound also shows bright radioluminescence with a light yield of 55 000 photons/MeV in the visible light region. Benefiting from these fascinating optical properties, high-performance single-component white light-emitting diode (WLED), NIR LED, and X-ray scintillator were fabricated based on Te 4+ /Mo 4+ -codoped Cs 2 ZrCl 6 /polydimethylsiloxane flexible film. Particularly, we took bullfrog palm as the target object, and demonstrated its applications in white light imaging, NIR imaging, and X-ray imaging, respectively. Without pixel mismatch and complicated imaging processing, the pixel-level X-ray to NIR image fusion was realized, which can not only observe the wound of bullfrog palm, but also clearly obtain the structure and distribution of blood vessels and skeleton textures under the skin tissue of bullfrog palm.
