An important intrinsic characteristic of resonant metamaterial surfaces is that enhanced electromagnetic fields are not uniformly distributed, resulting in spatially variable light-matter interactions with nanoparticle tags that signal the presence of biomarker molecules. In this work, the spatial uniformity of resonantly enhanced, surface-confined electromagnetic fields of a 1D PC is compared with a 2D PC with fourfold symmetry. When illuminated with unpolarized light, the simultaneously excited electromagnetic fields of transverse electric and transverse magnetic modes of the 2D PC present equally strong but complementary spatial distribution, leading to a >100% increased average near-field intensity accompanied with a >50% compressed standard deviation compared to the 1D PC. Utilizing Photonic Resonator Absorption Microscopy (PRAM) to experimentally measure the absorption uniformity of ≈80 nm gold nanoparticles distributed upon the PC surface, a >100% improvement of the signal uniformity is observed when using the 2D PC. Overall, improvement in AuNP detection contrast, uniformity, and point spread function is demonstrated by PRAM performed upon a 2D PC surface.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 6","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401837","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This final step of injecting fluid limits throughput and repeatability. This study presents an additive manufacturing process to create complex stretchable systems in which the liquid is directly printed as part of the fabrication process. The devices actuate straight out of the printing setup, with no further filling or sealing steps. In our fully printed approach for multi-layered structures, the key steps are the deposition of precisely shaped liquid droplets with sub-µL resolution, followed by their encapsulation using a freezing process to allow printing or spraying over the temporarily solid fluid drops. Printing both the fluid and the structure has advantages of: a) no filing channel, enabling very high fill-factors; b) design freedom as each device in array can be filled with a different volume; c) accuracy in filling. We demonstrate this process by printing arrays of 5 mm diameter stretchable hydraulically amplified taxels (HAXELs), consisting of nine flexible layers, with the working fluid included as part of the printing process.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 9","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401739","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on precise AJP control to enable high-resolution conformal electronics fabrication. Through randomized single-factor experiments, the effects of gas flow rates, focusing ratio, and print speed, highlighting the role of back pressure on focusing limits are examined. A computational fluid dynamics model, incorporating accurate particle size data, predicts aerosol stream width to expedite operating window identification. The interaction mechanisms between aerosol droplets and substrates are elucidated, achieving a resolution of 5 µm. A precision manufacturing protocol is developed, ensuring high-quality features with resolutions ranging from 10 to 300 µm across diverse 3D substrates without overspray.

Self-assembled monolayers of 3-Mercaptopropionic acid immobilized on the AuNP functionalized LIG-IDE are activated via carbodiimide chemistry for the binding of the anti-cortisol antibody. The resulting immunosensor is tested for the specific detection of cortisol over the physiologic range (0.1 pm–100 nm) in synthetic human sweat. Electrochemical impedance spectroscopy is used to measure the change in impedance due to cortisol bonding to the LIG surface. The sensor exhibits a good linear (log(concentration)) fit over the entire concentration range (R2 = 0.9662) and a LOD of 0.0085 nm. The minimal effect of synethtic sweat shows its potential use in real-world applications. A specificity test against similarly structured molecules demonstrates high affinity toward cortisol. Furthermore, the developed sensor exhibits excellent reproducibility with a 5.93%RSD. Given the simple and facile processability of immunosensors, the developed label-free AuNP functionalized LIG-based biosensing platform shows great promise as an effective and low-cost tool suitable for healthcare monitoring and point-of-care diagnostics, and it can be applied as an immunosensor for other affinity-based biosensors.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 9","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401040","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a contactless, efficient, terahertz (THz) investigation protocol based on the electromagnetic interaction between THz radiation and materials with subwavelength features is presented. On top of an opaque, lossy dielectric substrate a metal “open tag” is patterned as reference. This contains features that are visible to the naked eye, but subwavelength in the THz range. An identical dielectric substrate is then used to cover the metallic pattern and fabricate a “hidden tag.” Both tags are then scanned using a THz time-domain spectroscope (TDS). The collected spectra are used to evaluate different metrics, which provide valuable pixel-specific information for sample imaging. While the most common imaging techniques are demonstrated to be unsuitable for decoding hidden tags, a thorough study of the THz response allows to determine the best conditions for creating high-resolution images in both time- and frequency-domain. Effective metrics are obtained by isolating the peaks of the signal reflected from the tag or the substrates, or by suitably considering the interaction between the two signals. The proposed method provides a rigorous protocol for the THz imaging of hidden logos in multilayer systems, which can serve as anticounterfeiting tags.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 9","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401799","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, with a bandgap of 2.7 eV, CIPS-based devices are generally limited to operating in pure electrical mode or under ultraviolet light, making them unsuitable for applications across the entire visible light spectrum. Here, a two-terminal artificial synapse based on CIPS/MoS2/graphene heterojunction is constructed. Compared to ion migration or ferroelectricity under high bias voltage, photogating due to charge trapping is identified as the working mechanism under low bias voltage (< 1.5 V), which can respond to the shortest pulse (∼5 ms) and least energy consumption of 1.7 / 6.3 fJ per pulse up to date for CIPS-based synapses. Benefiting from the fading memory effect and nonlinear characteristics in visible light range, handwritten digit recognition based on reservoir computing has achieved an accuracy of 90.43% with four times higher efficiency than directly using an artificial neuron network. This work thus paves the way for constructing CIPS heterostructure for artificial vision and neuromorphic computing systems.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 9","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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, WO3/Ni(OH)2 composite high efficient electrochromic electrode materials are prepared by hydrothermal-annealing and electrodeposition methods. It is observed by experimental characterization that the deposition of Ni(OH)2 on WO3 rods effectively increased the Li+ diffusion rate of WO3 films (2.069 × 10−10 cm2 s−1), which is ≈1.5 times higher than that of pure WO3 (1.413 × 10−10 cm2 s−1). Meanwhile, WO3 and Ni(OH)2 have relatively matched energy level structures, showing high overall optical modulation performance. In addition, density functional theory (DFT) calculations combined with electrochemical studies reveal that the injection of double ions can improve the reaction efficiency of the electrodes and promote the redox reaction, which makes the electrochemical reaction more efficient.
