The hydrogen-bonding network of water interacts strongly with terahertz (THz) radiation, making THz waves a sensitive probe for evaluating water content. However, THz measurements of water concentration rely on effective medium theories that treat the sample as a binary mixture of water and non-aqueous components. This approach requires precise knowledge of the dielectric properties of the non-aqueous phase, often necessitating destructive sample preparation or oversimplified assumptions, which limit the accuracy and applicability. In this work, we present a non-destructive method for highly accurate water-content quantification. The method exploits the distinct temperature dependencies of THz absorption in water and non-aqueous substances. Theoretical analysis reveals a simple correlation between the THz absorption-temperature slope and the water volume fraction. By measuring samples at down to two temperatures within a narrow range of less than 10°C, water concentration can be determined with high precision in vitro . We validated the method across various materials, including liquid solutions, hydrated solids, and biological tissues from plants and animals. The extracted water contents show excellent agreement with theoretical or reference values, demonstrating broad applicability across samples with diverse compositions and hydration levels.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"14 1","pages":"230-230"},"PeriodicalIF":0.0,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional fluorescence microscopy allows for imaging of mitochondria selectively using fluorescent labeling, and consequently it suffers from phototoxicity and limited fluorescence channels. Quantitative phase contrast microscopy (QPCM) allows for imaging of tens of organelles in a label-free manner, yet it lacks the ability to distinguish specific organelles. In this work, we introduce an unsupervised deep learning model, entitled phase to fluorescence generative adversarial network (P2F-GAN). This model allows for virtual fluorescence labeling of mitochondria in QPCM images, eliminating the need for time-consuming paired training data acquisition. Utilizing an attention module and a customized loss function, P2F-GAN allows for virtual labeling of mitochondria (demonstrated as an example), achieving a structural similarity of 0.88, a Pearson correlation coefficient of 0.86, and a Dice coefficient of 0.84. The capability of the method has been demonstrated for tracking mitochondria in both physiological conditions and pharmacological interventions.

However, the superhydrophobicity of gold leads to a pronounced coffee-ring effect during the evaporation of liquid samples, resulting in uneven distribution of biomolecules and weakened light–matter interactions. Herein, we present a metallic terahertz (THz) metasurface sensor whose metal array region is modified with ionic liquids (ILs), resulting in a reduction of the droplet contact angle from 105.7° to 39.4°. This indicates excellent hydrophilicity, which facilitates the uniform deposition of protein molecules on the surface. This strategy circumvents the conventional dependence on high quality ( Q ) factor resonances and delivers outstanding sensing performance. Specifically, under y -polarized THz excitation, the two resonance modes excited by the metasurface enable reliable qualitative and quantitative detection of various proteins. Among these modes, Mode II exhibited a direct limit of detection (LoD) of 0.03125 mg/mL for insulin.

While innovations in TPFM technology, such as parallel-scanning, have drastically increased imaging speed, these improvements have typically focused on high frame rate, single field-of-view imaging rather than extending the area/volume imaging rate. In this work, we bridge the gap between high imaging speed and high area and volumetric imaging throughput by combining parallel scanning with tilted-plane strip-scanning using custom silicon photomultiplier (SiPM) tiled-array detectors. We demonstrate 200 MP/s with four spectral channels (800 MSpectra/s) and an effective area imaging speed of up to 52 mm2/s using four parallel beams. Custom detectors and lens array enable non-descanned imaging with minimal crosstalk combined with light collection efficiency comparable to a conventional single-point scanning TPFM. Finally, the low-cost of the custom detectors (~$250 per channel) and the scalability of the detection optics allow for ease of spectral multiplexing.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"13 9","pages":"2704-2717"},"PeriodicalIF":7.1,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12456228/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145138493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Terahertz (THz) spectroscopy, which resolves molecular structures by detecting intra- and intermolecular vibrational modes, has been enhanced through the integration with metasurfaces, extending its applications in biomedical and security detection. However, current methods face significant challenges in trace analysis and broadband detection of analytes. Here, we propose a novel metasurface-based approach for detecting molecular broadband fingerprint spectra, combining the simplicity of state-of-the-art THz angle-scanning methods with the specificity of molecular fingerprinting. Specifically, we designed a guided mode resonance (GMR) metasurface capable of providing localized electromagnetic field enhancement and continuous spectra between 0.95 and 1.45 THz. We demonstrate the enhanced detection of intrinsic absorption features of glutamic acid enantiomers by correlating the molecular absorption spectra with the reflectance spectra at each incident angle. This angle-scanning approach simplifies the identification process and spectroscopic system, offering the potential for miniaturization and field deployment of THz spectroscopic devices for molecular detection.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"13 11","pages":"3102-3102"},"PeriodicalIF":0.0,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147889090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we address these challenges through two key innovations. First, we develop a high-sensitivity acoustic-optical probe tailored for the SRS-based MW-OR-PAM system. The probe integrates a 9-μm-thick P(VDF-TrFE) film-based transducer between a planoconvex lens and a large-aperture acoustic lens, achieving a broad bandwidth (98.94%), a high numerical aperture (0.67), and adjustable optical focusing. Second, we introduce tartrazine, a biocompatible and tissue-transparent dye, to induce reversible optical clearing in vivo , thereby enhancing light penetration at wavelengths above 600 nm. These advances significantly improve microvascular imaging at longer wavelengths. We validate the performance of our system through high-resolution imaging of skin microvasculature, oxygen saturation mapping, and transcranial brain imaging.

Correcting scattering becomes particularly challenging in scenarios with limited photon availability and when access to the transmission side of the scattering tissue is not possible. Here, we introduce, to our knowledge, a new two-photon microscopy system with Fourier-domain intensity coupling for scattering correction (2P-FOCUS). 2P-FOCUS corrects scattering by intensity modulation in the Fourier domain, leveraging the nonlinearity of multiple-beam interference and two-photon excitation, eliminating the need for a guide star, iterative optimization, or measuring transmission or reflection matrices. 2P-FOCUS uses random patterns to probe scattering properties, combined with a single-shot algorithm to rapidly generate the correction mask. 2P-FOCUS can also correct scattering beyond the limitation of the memory effect by automatically customizing correction masks for each subregion in a large field-of-view. We provide several proof-of-principle demonstrations here, including focusing and imaging through a bone sample, and imaging neurons and cerebral blood vessels in the mouse brain ex vivo. 2P-FOCUS significantly enhances two-photon fluorescence signals by several tens of folds compared to cases without scattering correction at the same excitation power. 2P-FOCUS can also correct tissue scattering over a <math><mn>230</mn> <mspace></mspace> <mi>μ</mi> <mtext>m</mtext> <mo>×</mo> <mn>230</mn> <mspace></mspace> <mi>μ</mi> <mtext>m</mtext> <mo>×</mo> <mn>510</mn> <mspace></mspace> <mi>μ</mi> <mtext>m</mtext></math> volume, which is beyond the memory effect range. 2P-FOCUS is able to measure, calculate, and correct scattering within a few seconds, effectively delivering more light deep into the scattering tissue. 2P-FOCUS could be broadly adopted for deep tissue imaging owing to its powerful combination of effectiveness, speed, and cost.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"13 4","pages":"845-864"},"PeriodicalIF":6.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12225971/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144560776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
