The colorimetric sensor utilizes the glucose oxidase-like (GOx) and peroxidase-like (POD) activities of P1 to detect glucose and UA. When P1 is present in a solution of glucose and 3,3′5,5′-tetramethylbenzidine (TMB), P1 catalyzes two cascade reactions: one between glucose and O2 and the other between TMB and as-generated hydrogen peroxide (H2O2). The latter reaction provides visual results of glucose analysis with a LOD of 0.04 mm in the range of 0–40 mm in human serum samples. Furthermore, when P1 is present in a solution of UA, TMB, and H2O2, P1 catalyzes cascade reactions: one reaction between UA and H2O2 and the other reaction between TMB + H2O2. UA suppresses the POD-like activity of P1 to detect UA with a LOD of 0.15 µm in the range of 10 µm–1.5 mm in urine samples. P1 exhibits dual enzyme mimetic activities for efficient detection of glucose and UA in real samples. The as-designed colorimetric sensors display high selectivity, good stability, excellent specificity, and desirable practicability for detecting glucose and UA in real samples.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 19","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230654","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, macroscopic phase-change drug carriers are demonstrated in the form of millimeter-sized balls, which offer enhanced visibility. These wax-based phase-change macroballs, composed of paraffin, fatty alcohols, or fatty acids, can be easily fabricated with customizable volumes by depositing melted wax droplets containing functional components–such as drugs, photothermal agents, surfactants, and magnetites–onto omniphobic surfaces, where they spontaneously dewet and solidify upon natural cooling. These macroballs can be rapidly heated and melted upon near-infrared irradiation due to the incorporation of low-melting-point liquid metal (LM) eutectic Ga–In microdroplets as photothermal agents, enabling efficient on-demand drug release. Furthermore, by adsorbing magnetically susceptible Fe₃O₄ nanoparticles onto the LM microdroplets, the transport of the macroballs becomes magnetically controllable, as demonstrated by the use of a permanent magnet or electromagnet.

However, conventional batch syntheses exhibit shortcomings that bind the control over the reaction parameters and batch-to-batch reproducibility. Droplet-based microfluidics represents a valuable strategy to overcome these constraints, enabling precise manipulation of fluids/molecules to design nanoscaffolds. Standard microfluidic fabrication methods, such as soft lithography, hot-embossing or molding, require multistep process, and the successful fabrication depends on several factors, including the operator expertise. This work proposes two-photon polymerization (TPP) 3D printing as a straightforward method to produce a microfluidic device for droplet-based synthesis of NGs. The microfluidic platform enables controlled generation of microdroplets (150–80 µm, with size variation up to 47%), which work as microreactors, allowing modulation of NG dimensions (320–175 nm) and properties, while preserving an extremely low polydispersity (<0.1). NGs composed of polyallylamine and hyaluronic acid are synthesized and evaluated in vitro for cisplatin delivery in ovarian cancer cells. Compared to free drug administration, NG-mediated delivery enhances the therapeutic effect by ≈30% after 72 h. This highlights the potential of the nanomaterial in tumoral scenarios and proves the functionality of the TPP-printed microfluidic device in NG droplet-based synthesis.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 19","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202500108","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230787","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}

To address this issue, this paper presents a reconfigurable soft actuator with tunable deformation and stiffness (RATDS). The soft actuator consists of a skeleton and a thermoplastic polyurethane (TPU) skin. The skeleton is composed of two shapes of cavity units with particles filled and a polyethylene terephthalate (PET) sheet. It can realize various deformations with different assembly models of the cavity units under vacuum pressure. Stiffness variation is achieved by increasing vacuum pressure, causing the cavities to shrink and leading to particle jamming. The convenient manufacturing and assembly methods are demonstrated. The finite element analysis (FEA) simulations and experiments show that the actuator's deformation can transition from 2D bending to 3D twisting and multi-direction deformation with different assembly models, respectively. Durability experiments confirm its functionality even after 5000 cycles. The actuator exhibits fast response time (0.35 s) excellent stiffness enhancement (from 0.019 N mm−1 (0 kPa) to 0.219 N mm−1(−40 kPa)) and good tip force (averaging 3.85 N).

Memristors, which combine memory and computation in a compact device, offer a promising solution for real-time hardware-based temporal data analysis. This perspective reviews how memristors are used in time-series processors, focusing on two main approaches: conventional reservoir computing (RC) architectures and newly emerging temporal kernels (TKs). While RC systems often rely on volatile memristors and network structures to extract features from time-varying signals, TKs enhance flexibility by combining memristors with circuit elements like resistors, capacitors, or semiconductor devices. This feature allows precise tuning of signal delays, thresholds, and nonlinear behaviors. Several representative TK designs and variations are introduced, each with strengths in capturing different temporal features. These are well suited for edge applications where quick and selective signal processing is essential. Future efforts must focus on optimizing kernel behavior and integrating TKs directly with sensors to move toward practical use. This direction can enable real-time tasks such as on-device health monitoring, biometric authentication, and adaptive sensing, positioning memristive TKs as a core technology for next-generation intelligent edge systems.","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 15","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202500838","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782914","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}

Soft hollow pillars (SHPs) have demonstrated to have exceptional adhesion tunability under pneumatic actuation through sidewall buckling or bulging mechanisms. However, the adhesion strength of SHPs is significantly lower than that of solid elastomeric pillars, which can limit their practical use. In this study, mushroom-shaped SHPs with a mushroom cap, or capped SHPs (C-SHPs), are introduced to enhance the adhesion performance of soft grippers based on hollow pillar structures. Experiments and finite element modeling demonstrate that the cap significantly improves adhesion strength (1.8 to 2.9×) and adhesion tunability (∼1000×) by optimizing stress distribution and altering the crack initiation process at the contact interface. The effect of the cap size on the adhesion strength of C-SHPs under various pressures is systematically investigated. Miniaturized SHPs and C-SHPs are fabricated for pick-and-place manipulation of lightweight objects. An untethered device containing a C-SHP is designed and assembled to highlight the energy-efficient operation of C-SHPs, with a ∼139 mJ energy consumption per pick-and-place cycle, showcasing their potential for applications in precision handling tasks.
