Existing imaging tools often fail to reliably differentiate between ER-positive and ER-negative cancer cells. To address this limitation, two novel fluorescent probes, E2N and E2R, are synthesized by conjugating estradiol to styryl and rhodamine-based fluorophores using click chemistry. These probes are characterized by their photophysical properties, biocompatibility, and selective targeting of ER-positive cells. Cellular uptake studies demonstrate preferential internalization of E2N and E2R in ER-positive MCF-7, ZR-75-1, and T-47D cells, with minimal uptake in ER-negative MDA-MB-231, MDA-MB-468, and healthy COS-7 and NIH-3T3 cell lines. Kinetic studies reveal efficient and rapid uptake of E2N in ER-positive MCF-7 cells, while mechanistic investigations identified clathrin-mediated endocytosis as the receptor-mediated pathway for both probes. Localization studies further confirm their mitochondrial specificity in ER-positive cells, with E2R displaying higher mitochondrial selectivity. These findings underscore the potential of E2N and E2R as powerful tools for distinguishing ER-positive from ER-negative breast cancer cells. Their receptor-mediated targeting and precise imaging capabilities make them promising candidates for advancing breast cancer diagnostics and enabling more targeted therapeutic strategies.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 8","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, integrating these materials into device architectures with CMOS-compatible technologies in a simple manner remains a critical challenge. This study introduces a universal method leveraging standard lithographic patterning to fabricate high-performance LHP PDs for red (R), green (G), and blue (B) color detection separately. Through optimization of the device stack and etching conditions, perovskite PDs are pixelated using a one-step lithography and pulsed argon (Ar) milling process. The resulting devices exhibit typical perovskite PD responsivity (0.3 A W−1), low dark current density (less than 10−6 mA cm−2), high detectivity (over 1013 Jones), and short fall time (sub-20 ns without bias). This approach not only enhances device performance but also paves the way for scalable production of perovskite-based optoelectronic devices. The versatility and effectiveness of this method highlight its potential for broad applicability in CMOS-compatible perovskite-based image sensor technology.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 10","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, hierarchical microspheres (HMs) with a two-tier structure, composed of SiO2, TiO2-coated SiO2, BaSO4, or PNIPAM, are incorporated into PDMS-based composites. These microspheres feature larger spheres assembled from submicrometer-scale nanoparticles and are fabricated via microfluidics to enhance radiative cooling performance. SiO2 HMs not only boost visible light reflection and exhibit structural color through a photonic stop band but also achieve an average emissivity of 97.55% in the atmospheric window. Both experimental and simulated results show that HMs enhance the emissivity performance of the composite material compared with solid SiO2 microspheres of the same diameter. Additionally, applying TiO2 coating to SiO2 HMs further increases the overall emissivity to 98.05%. Incorporating BaSO4 HMs also increased the average visible reflectivity to 96.56%, while maintaining superior infrared emissivity at 97.58%. The inclusion of PNIPAM spheres enabled temperature-responsive transmissivity, with the composite materials containing PNIPAM and SiO2 HMs preserving high infrared emissivity in the atmospheric window.

Most of the newly synthesized dyes show high dichroic ratios and order parameters, ensuring strong optical anisotropy and good alignment within the liquid crystal host mixture. The performance of individual dyes in smart window applications is evaluated, with transmittance changes observed under dynamic electric fields, demonstrating their potential for use in electrically tunable smart windows. To achieve full visible-light modulation, the combination of complementary absorption dyes is screened and an optimized mixture Mix-7 is obtained, which not only achieves full visible-light absorption coverage but also demonstrates smooth and dynamic transmittance modulation under varying voltages. Finally, a prototype smart window filled with Mix-7 is fabricated to validate the continuous tunability of dye-doped liquid crystal-based systems. Additionally, further introduction of a polarizer film significantly reduces the transmittance of the demo, especially in the OFF state which presents an almost completely dark state, highlighting the potential for automotive smart window applications.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 8","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, perovskite structures are sensitive to water and humid environments, which leads to decomposition, and they decisively limit stability through surface ligand and structure control. Herein, an approach using 3-mercaptopropyltrimethoxysilane (MPTMS) among silane materials with the advantages of chemical stability and nontoxicity is proposed. The excellent structural properties of MPTMS are confirmed by the interaction of the Pb-S, which formed an interparticle network through the reaction of the methoxy group bonded to Si. Additionally, fabricated PQDs indicate superior optical performance by suppressing the approach to moisture and acetone solvents. Particularly, silane passivation of the particles conferred hydrophobicity, as confirmed via contact angle and surface energy analysis. Furthermore, silane networks are formed through the MPTMS ligand exchange strategy, suggesting that PQDs are a facile platform for maintaining high quality in aqueous environments.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 11","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their effectiveness as solar energy transmission modulators is limited because they only reflect circularly polarized light of a specific handedness (either right- or left-handed) over a relatively narrow bandwidth (≈100 nm). In this work, these limitations are addressed using a waveplate. To enhance the reflective properties, a waveplate is placed between two baseline oligomers. By optimizing the waveplate thickness, the device switches between reflecting right-circularly polarized light at room temperature to reflecting unpolarized, ambidextrous light at 60 °C. Next, this system is combined with a second reflective cholesteric liquid crystal oligomer with the same reflection band at room temperature but with a smaller thermochromic response. This enables the device to transition from a narrow band reflection to broad band ambidextrous reflection upon heating, resulting in a solar transmission modulation of 5.2% which is four times greater than typical thermochromic cholesteric liquid crystal reflectors marking a significant step toward their application in smart solar heat-modulating windows.
