Electrochemical affinity biosensors have the potential to facilitate the development of multiplexed point-of-care diagnostics in complex biological fluids. However, their commercial viability has been hindered by challenges such as electrode biofouling and the lack of inherent redox properties. To address this unmet need, we have developed a universal nanocomposite coating which is unique in its ability to not only allow oriented conjugation of the biorecognition element but also specific detection directly in complex biological fluids like serum and urine owing to its built-in antifouling and redox capabilities, thus improving suitability for point of care testing. This multifunctional coating comprises a 3D porous crosslinked bovine serum albumin matrix for oriented conjugation and antifouling properties with embedded graphene nanosheets modified with amino-ferrocene for enhanced conductivity and mediator-free biosensing. The coating showed minimal signal degradation despite prolonged exposure to 1% bovine serum albumin, artificial urine and untreated human serum for up to 30 days. To demonstrate its utility, we fabricated and tested proof-of-concept electrochemical immunosensors for bladder cancer protein biomarkers, specifically interleukin-8 (IL-8) and vascular endothelial growth factor (VEGF). The practical feasibility was highlighted by the excellent sensitivity and specificity observed for IL-8 and VEGF with a limit of detection of 41 pg mL−1 and 67 pg mL−1, respectively. Consequently, this universal nanocomposite-based electrochemical biosensing platform can be extended to the point of care testing of a broad spectrum of biomarkers present in complex biological fluids, thus enabling reliable and early diagnostics. © 2024 The Royal Society of Chemistry

Zwitterion-Functionalized Cuprous Oxide Nanoparticles for Highly Specific and Enzymeless Electrochemical Creatinine Biosensing in Human Serum

引用

ACS Applied Nano Materials 2023年第3期6卷 2083-2094页

作者： Rakesh Kumar, R.K. Shaikh, Muhammad Omar Kumar, Amit Liu, Chi-Hao Chuang, Cheng-Hsin Institute of Medical Science and Technology National Sun Yat-sen University Kaohsiung80424 Taiwan Sustainability Science and Engineering Program Tunghai University Taichung407224 Taiwan Division of Nephrology Department of Internal Medicine Kaohsiung Armed Forces General 632 Hospital Kaohsiung80284 Taiwan

Herein, we report the development of a novel enzymeless electrochemical biosensor for highly specific detection of creatinine utilizing zwitterion-functionalized cuprous oxide nanoparticles (Cu2O NPs). We utilized a simple yet effective alternative to traditionally used cover layers based on the surface engineering of Cu2O NPs with N-hexadecyl-N,N dimethyl-3-ammonio-1-propanesulfonate zwitterion. This surface modification generates a pseudo-proton-exchange membrane which electrostatically hinders interfering agents from reaching the electrode surface, thus resulting in highly specific creatinine detection without loss in sensitivity. To fabricate the enzymeless biosensor, single-crystalline Cu2O NPs were synthesized via a sulfonate ion-directed seed aging protocol and were simply drop-cast onto screen-printed carbon electrodes. The shape directional effect of sulfonate ions to induce truncation in the final morphologies of the synthesized Cu2O NPs is also reported for the first time. The creatinine biosensor demonstrated fast response time (2 = 0.9876 and LOD = 5.0 μM) was observed, which covers the entire range of physiological creatinine in human serum. Moreover, robust storage stability with a negligible decrease in signal strength over an extended storage period of 6 months was achieved, thus highlighting the practical feasibility for point-of-care testing of creatinine. © 2023 American Chemical Society.

Novel entrance and exit designs towards fully developed dual Vortexes in cyclone separators

Stairmand-type cyclones are commonly used in industry to separate particles from gas streams by inertia, driven by the dual-vortex flow patterns. Here, new designs are proposed to eliminate the local non-ideal vortex patterns in a conventional Stairmand cyclone by inserting a flow divider at the entrance and adjusting the elbow exit orientation. A two-way coupled CFD–DPM approach is employed to analyze the performance of the modified cyclones. Simulation results show that the cyclone with the elbow exit oriented orthogonal to the entrance direction demonstrates better performance in terms of the cut size and sharpness. The installation of the flow divider reduces the vortex eccentricity by approximately 50%. The flow divider increases the gas velocity near the outer wall, allowing the quasi-free vortex in the cyclone's outer region to become nearly fully developed at the entrance section through the reduction of the local secondary recirculation flows. The optimum flow divider outer wall thickness correlates to the wall shear stress distribution. With the optimum 2 mm outer wall thickness flow divider installed, the separation efficiency for 2 μm particles increases from 56.74% to 77.4%, and the cut size decreases from 1.87 μm to 1.23 μm. © 2025 The Society of Powder Technology Japan

Additive manufacturing is an innovative production approach aimed at creating products that traditional techniques cannot produce with the desired quality and requirements. Throughout the additive manufacturing process, data is either used (such as materials properties, printer characteristics and settings) or generated (such as monitoring data during printing, slicing strategies setting parameters). However, managing such data with complex relationships remains a significant challenge in both research and industry in the additive manufacturing field. To address this issue, we developed a modular ontology that can be used as the basis for a framework that supports decision-making systems, facilitate semanticsaware data management, and enhance the understanding and optimization of additive manufacturing processes. In this paper we focus on one of the state-of-the-art additive manufacturing approaches, i.e., powder bed fusion. To show the use and the feasibility of our approach, we created a knowledge graph for an actual additive manufacturing experiment based on our ontology, and show how queries relevant to domain experts can be answered using this knowledge graph. © 2024 CEUR-WS.

Inundation mechanisms and overbank water quality along the lower Mississippi River during the major floods of 2018, 2019, and 2020

Journal of Hydrology 2025年 661卷

Artificially narrowed embanked floodplains, like those along the lower Mississippi River (LMR), are limited in their capacity to attenuate flooding and maximize nutrient retention. This study examines mechanisms and patterns of inundation during three major LMR floods (2018–2020) by analyzing water levels and temperatures from continuously operating sensors. Additionally, in-situ water quality measurements and overbank water samples collected in 2019 were analyzed for sediment, sorbed carbon and nutrients, and dissolved nutrients. Results indicate that subsurface seepage during the early rising limb initiates water-level increases in deep floodplain water bodies, followed by backwater inundation of distal floodplains, crevasse activation, and finally overtopping of natural levees near maximum stages. Overbank water samples from March and June 2019 indicate that dissolved nitrate-nitrite (54% & 24% less), phosphorus (27% & 29% less), and suspended-sediment concentrations (70% & 59% less) were lower than the LMR channel upstream, indicating nutrient retention and sediment deposition in the embanked floodplain;findings are partly supported by declining trends with distance from the channel bank. Conversely, mass percentages of sorbed carbon (235% & 68% more) and nitrogen (300% & 125% more) were higher than the LMR channel, resulting from sand deposition on natural levees and continued suspension of adsorptive fine-grained sediments. Subsequent fine-grained settling retains carbon and nitrogen in floodplain deposits. These findings establish that modes and patterns of sediment deposition and nutrient retention vary as stages adjust during long-duration floods, and while deeply inundated embanked floodplains remain capable of retention, fine sediment and nutrients primarily bypass downstream. © 2025 Elsevier B.V.
