    Dynamic synthetic-scanning photoacoustic tracking monitors hepatic and renal clearance pathway of exogeneous probes in vivo

    查看更多>>摘要：Advancements in precision medicine necessitate understanding drug clearance pathways,especially in organs like the liver and kidneys.Traditional techniques such as PET/CT pose radiation hazards,whereas optical imaging poses challenges in maintaining both depth penetration and high resolution.Moreover,very few longitudinal studies have been performed for drug candidates for different symptoms.Leveraging non-ionizing photoacoustic tomography for deep tissue imaging,we developed a spatiotemporally resolved clearance pathway tracking(SRCPT)method,providing unprecedented insights into drug clearance dynamics within vital organs.SRCPT addresses challenges like laser fluence attenuation,enabling dynamic visualization of drug clearance pathways and essential parameter extraction.We employed a novel frequency component selection based synthetic aperture focusing technique(FCS-SAFT)with respiratory-artifacts-free weighting factors to enhance three-dimensional imaging resolutions.Inspired by this,we investigated the clearance pathway of a clinical drug,mitoxantrone,revealing reduced liver clearance when hepatic function is impaired.Furthermore,immunoglobulin G clearance analysis revealed significant differences among mice with varying renal injury degrees.The accuracy of our method was validated using a double-labeled probe[68Ga]DFO-IRDye800CW,showing a strong positive correlation between SRCPT and PET.We believe that this powerful SRCPT promises precise mapping of drug clearance pathways and enhances diagnosis and treatment of liver and kidney-related diseases.

    查看更多>>摘要：Quantitative phase imaging(QPI)recovers the exact wavefront of light from intensity measurements.Topographical and optical density maps of translucent microscopic bodies can be extracted from these quantified phase shifts.We demonstrate quantitative phase imaging at the tip of a coherent fiber bundle using chromatic aberrations inherent in a silicon nitride hyperboloid metalens.Our method leverages spectral multiplexing to recover phase from multiple defocus planes in a single capture using a color camera.Our 0.5 mm aperture metalens shows robust quantitative phase imaging capability with a 28°field of view and 0.2π phase resolution(～0.1λ in air)for experiments with an endoscopic fiber bundle.Since the spectral functionality is encoded directly in the imaging lens,the metalens acts both as a focusing element and a spectral filter.The use of a simple computational backend will enable real-time operation.Key limitations in the adoption of phase imaging methods for endoscopy such as multiple acquisition,interferometric alignment or mechanical scanning are completely mitigated in the reported metalens based QPI.

    查看更多>>摘要：Understanding the morphology and function of large-scale cerebrovascular networks is crucial for studying brain health and disease.However,reconciling the demands for imaging on a broad scale with the precision of high-resolution volumetric microscopy has been a persistent challenge.In this study,we introduce Bessel beam optical coherence microscopy with an extended focus to capture the full cortical vascular hierarchy in mice over 1000×1000×360 μm3 field-of-view at capillary level resolution.The post-processing pipeline leverages a supervised deep learning approach for precise 3D segmentation of high-resolution angiograms,hence permitting reliable examination of microvascular structures at multiple spatial scales.Coupled with high-sensitivity Doppler optical coherence tomography,our method enables the computation of both axial and transverse blood velocity components as well as vessel-specific blood flow direction,facilitating a detailed assessment of morpho-functional characteristics across all vessel dimensions.Through graph-based analysis,we deliver insights into vascular connectivity,all the way from individual capillaries to broader network interactions,a task traditionally challenging for in vivo studies.The new imaging and analysis framework extends the frontiers of research into cerebrovascular function and neurovascular pathologies.

    Highly-efficient(＞70％)and Wide-spectral(400-1700 nm)sub-micron-thick InGaAs photodiodes for future high-resolution image sensors

    查看更多>>摘要：This paper demonstrates the novel approach of sub-micron-thick InGaAs broadband photodetectors(PDs)designed for high-resolution imaging from the visible to short-wavelength infrared(SWIR)spectrum.Conventional approaches encounter challenges such as low resolution and crosstalk issues caused by a thick absorption layer(AL).Therefore,we propose a guided-mode resonance(GMR)structure to enhance the quantum efficiency(QE)of the InGaAs PDs in the SWIR region with only sub-micron-thick AL.The TiOx/Au-based GMR structure compensates for the reduced AL thickness,achieving a remarkably high QE(＞70％)from 400 to 1700 nm with only a 0.98 μm AL InGaAs PD(defined as 1 μm AL PD).This represents a reduction in thickness by at least 2.5 times compared to previous results while maintaining a high QE.Furthermore,the rapid transit time is highly expected to result in decreased electrical crosstalk.The effectiveness of the GMR structure is evident in its ability to sustain QE even with a reduced AL thickness,simultaneously enhancing the transit time.This breakthrough offers a viable solution for high-resolution and low-noise broadband image sensors.

    Topological protection of optical skyrmions through complex media

    An Aloysius WangZimo ZhaoYifei MaYuxi Cai...
    3236-3252页
    查看更多>>摘要：Optical Skyrmions have many important properties that make them ideal units for high-density data applications,including the ability to carry digital information through a discrete topological number and the independence of spatially varying polarization to other dimensions.More importantly,the topological nature of the optical Skyrmion heuristically suggests a strong degree of robustness to perturbations,which is crucial for reliably carrying information in noisy environments.However,the study of the topological robustness of optical Skyrmions is still in its infancy.Here,we quantify this robustness precisely by proving that the topological nature of the Skyrmion arises from its structure on the boundary and,by duality,is resilient to spatially varying perturbations provided they respect the relevant boundary conditions of the unperturbed Skyrmion.We then present experimental evidence validating this robustness in the context of paraxial Skyrmion beams against complex polarization aberrations.Our work provides a framework for handling various perturbations of Skyrmion fields and offers guarantees of robustness in a general sense.This,in turn,has implications for applications of the Skyrmion where their topological nature is exploited explicitly,and,in particular,provides an underpinning for the use of optical Skyrmions in communications and computing.

    Single-shot single-beam coherent Raman scattering thermometry based on optically induced air lasing

    3253-3260页
    查看更多>>摘要：Thermometric techniques with high accuracy,fast response and ease of implementation are desirable for the study of dynamic combustion environments,transient reacting flows,and non-equilibrium plasmas.Herein,single-shot single-beam coherent Raman scattering(SS-CRS)thermometry is developed,for the first time to our knowledge,by using air lasing as a probe.We show that the air-lasing-assisted CRS signal has a high signal-to-noise ratio enabling single-shot measurements at a 1 kHz repetition rate.The SS-CRS thermometry consistently exhibits precision of＜2.3％at different temperatures,but the inaccuracy grows with the increase in temperature.The high measurement repeatability,1 kHz acquisition rate and easy-to-implement single-beam scheme are achieved thanks to the unique temporal,spectral and spatial characteristics of air lasing.This work opens a novel avenue for high-speed CRS thermometry,holding tremendous potential for fast diagnostics of transient reacting flows and plasmas.

    A multiband NIR upconversion core-shell design for enhanced light harvesting of silicon solar cells

    3261-3271页
    查看更多>>摘要：Exploring lanthanide light upconversion(UC)has emerged as a promising strategy to enhance the near-infrared(NIR)responsive region of silicon solar cells(SSCs).However,its practical application under normal sunlight conditions has been hindered by the narrow NIR excitation bandwidth and the low UC efficiency of conventional materials.Here,we report the design of an efficient multiband UC system based on Ln3+/Yb3+-doped core-shell upconversion nanoparticles(Ln/Yb-UCNPs,Ln3+=Ho3+,Er3+,Tm3+).In our design,Ln3+ions are incorporated into distinct layers of Ln/Yb-UCNPs to function as near-infrared(NIR)absorbers across different spectral ranges.This design achieves broad multiband absorption withtin the 1100 to 2200 nm range,with an aggregated bandwidth of～500 nm.We have identified a synthetic electron pumping(SEP)effect involving Yb3+ions,facilitated by the synergistic interplay of energy transfer and cross-relaxation between Yb3+and other ions Ln3+(Ho3+,Er3+,Tm3+).This SEP effect enhances the UC efficiency of the nanomaterials by effectively transferring electrons from the low-excited states of Ln3+to the excited state of Yb3+,resulting in intense Yb3+luminescence at～980 nm within the optimal response region for SSCs,thus markedly improving their overall performance.The SSCs integrated with Ln/Yb-UCNPs with multiband excitation demonstrate the largest reported NIR response range up to 2200 nm,while enabling the highest improvement in absolute photovoltaic efficiency reported,with an increase of 0.87％(resulting in a total efficiency of 19.37％)under standard AM 1.5 G irradiation.Our work tackles the bottlenecks in UCNP-coupled SSCs and introduces a viable approach to extend the NIR response of SSCs.

    Simultaneous achieving negative photoconductivity response and volatile resistive switching in Cs2CoCl4 single crystals towards artificial optoelectronic synapse

    3272-3284页
    查看更多>>摘要：The development of negative photoconductivity(NPC)-related devices is of great significance for numerous applications,such as optoelectronic detection,neuromorphic computing,and optoelectronic synapses.Here,an unusual but interesting NPC phenomenon in the novel cesium cobalt chlorine(Cs2CoCl4)single crystal-based optoelectronic devices is reported,which simultaneously possess volatile resistive switching(RS)memory behavior.Joint experiment-theory characterizations reveal that the NPC behavior is derived from the intrinsic vacancy defects of Cs2CoCl4,which could trap photogenerated charge carriers and produce an internal electric field opposite to the applied electric field.Such NPC effect enables an abnormal photodetection performance with a decrease in electrical conductivity to illumination.Also,a large specific detectivity of 2.7×1012 Jones and broadband NPC detection wavelength from 265 to 780 nm were achieved.In addition to the NPC response,the resulting devices demonstrate a volatile RS performance with a record-low electric field of 5 x 104V m-1.By integrating the characteristics of electric-pulse enhancement from RS and light-pulse depression from NPC,an artificial optoelectronic synapse was successfully demonstrated,and based on the simulation of artificial neural network algorithm,the recognition application of handwritten digital images was realized.These pioneer findings are anticipated to contribute significantly to the practical advancement of metal halides in the fields of in-memory technologies and artificial intelligence.

    Unlocking high-performance near-infrared photodetection:polaron-assisted organic integer charge transfer hybrids

    查看更多>>摘要：Room temperature femtowatt sensitivity remains a sought-after attribute,even among commercial inorganic infrared(IR)photodetectors(PDs).While organic IR PDs are poised to emerge as a pivotal sensor technology in the forthcoming Fourth-Generation Industrial Era,their performance lags behind that of their inorganic counterparts.This discrepancy primarily stems from poor external quantum efficiencies(EQE),driven by inadequate exciton dissociation(high exciton binding energy)within organic IR materials,exacerbated by pronounced non-radiative recombination at narrow bandgaps.Here,we unveil a high-performance organic Near-IR(NIR)PD via integer charge transfer between Poly[2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene](C-14PBT TT)donor(D)and Tetrafluorotetracyanoquino-dimethane(TCNQF4)acceptor(A)molecules,showcasing strong low-energy subgap absorptions up to 2.5 μm.We observe that specifically,polaron excitation in these radical and neutral D-A blended molecules enables bound charges to exceed the Coulombic attraction to their counterions,leading to an elevated EQE(polaron absorption region)compared to Frenkel excitons.As a result,our devices achieve a high EQE of～107％,femtowatt sensitivity(NEP)of～0.12 fW Hz 1/2 along a response time of～81 ms,at room temperature for a wavelength of 1.0 μm.Our innovative utilization of polarons highlights their potential as alternatives to Frenkel excitons in high-performance organic IR PDs.

    3297-3306页
    查看更多>>摘要：Inorganic luminescent materials hold great promise for optoelectronic device applications,yet the limited efficiency and poor thermal stability of oxide-based deep-red emitting phosphors hinder the advancement of plant lighting technologies.Herein,a simple compositional engineering strategy is proposed to stabilize the phase,boost external quantum efficiency(EQE)and enhance thermal stability.The chemical modification of the PO4 tetrahedron in NaMgPO4:Eu by incorporating SiO4 lowers the formation energy,leading to the generation of pure olivine phase and increasing the EQE from 27％to 52％,setting a record for oxide deep-red phosphors.In parallel,the introduced deep defect level improves thermal stability at 150 ℃ from 62.5％to 85.4％.Besides,the excitation and emission peaks shifted to 440 nm and 675 nm,respectively,aligning precisely with the specific spectral absorption requirements of plant phytochromes.Moreover,the luminescent intensity showed nearly no decay after being exposed to 80％relative humidity and 80 ℃ for 6 h,and the pc-LED utilizing Na1.06MgP0.94Si006O4:Eu achieves a high output power of 780 mW at 300 mA.Our research demonstrates a facile method for optimizing the performance of inorganic luminescent materials and provides alternative solutions for low-cost plant lighting.
