Extracellular vesicles (sEVs) are promise as biomarkers for early cancer diagnostics and prognostics. Immunoaffinity-based isolation techniques using antibodies for specific sEV surface proteins offer high specificity and purity. However, researchers struggle with isolating rare sEV subtypes, achieving sufficient throughput and managing harmless release. To address these challenges, we developed the ExoOnco chip, a microfluidic device featuring a radial flow design with bean-shaped micro-posts that create a varying shear rate profile for efficient sEV capture. This device integrates the catalyst-free, biocompatible, and biorthogonal Inverse electron demand Diels-Alder (IEDDA), conjugated with antibodies for the rapid and precise isolation of rare sEV subtypes. Additionally, our modified chemistry incorporates a reducible disulfide bridge for simple release of captured sEVs. We successfully captured and released sEVs expressing high levels of epithelial cellular adhesion molecule (EpCAM) from cell line media and non-small cell lung cancer (NSCLC) patient plasma. Following captured, we show the potential for characterizing isolated sEV using WB and micro-bicinchoninic acid assay. We have illustrated our device's specificity towards tumor derived sEVs (TDEs) utilizing patient and healthy plasma to show a significant difference in TAA expression level using dPCR analysis. By implementing the rapid IEDDA chemistry and functional disulfide bridge, the improved ExoOnco Chip facilitates the isolation and release of rare TDEs, enabling further investigation of their bioactive constituents. This technology opens avenues for advancements in early-stage cancer diagnosis and adaptive immunotherapies based on these bioactive constituents.

细胞外囊泡（sev）有望作为早期癌症诊断和预后的生物标志物。基于免疫亲和的特异性sEV表面蛋白抗体分离技术具有高特异性和纯度。然而，研究人员努力分离罕见的sEV亚型，实现足够的吞吐量和管理无害释放。为了应对这些挑战，我们开发了ExoOnco芯片，这是一种微流体装置，具有径向流设计，具有豆状微柱，可创建不同的剪切速率剖面，以实现高效的sEV捕获。该装置集成了无催化剂、生物相容性和双正交反电子需求Diels-Alder (IEDDA)，与抗体结合，用于快速、精确地分离罕见的sEV亚型。此外，我们的改性化学包含一个可还原的二硫桥，用于简单释放捕获的sev。我们成功地从细胞系培养基和非小细胞肺癌（NSCLC）患者血浆中捕获并释放了表达高水平上皮细胞粘附分子（EpCAM）的sev。在捕获后，我们展示了使用WB和微量双霉素酸测定鉴定分离sEV的潜力。我们利用患者和健康血浆说明了我们的设备对肿瘤源性sev （TDEs）的特异性，并使用dPCR分析显示TAA表达水平的显着差异。通过实现快速IEDDA化学和功能二硫桥，改进的ExoOnco芯片促进了稀有tde的分离和释放，从而进一步研究其生物活性成分。这项技术为基于这些生物活性成分的早期癌症诊断和适应性免疫疗法的进步开辟了道路。

This study presents the development, integration, and experimental validation of a smart total hip replacement (THR) system that combines piezoelectric load sensing, energy harvesting, and wireless data transmission. The implant incorporates seven piezoelectric sensors embedded within the femoral head, strategically positioned using Finite Element Analysis (FEA) to identify high-strain contact zones during gait. A customized cam-driven benchtop setup simulated cyclic loading at walking (2 Hz), jogging (3 Hz), and running (4 Hz) frequencies to evaluate the sensor system under physiologically relevant conditions. The results confirmed the implant’s ability to capture localized load variations with high spatial fidelity and repeatability, as sensor output correlated strongly with applied force across dynamic trials. RMS voltage-load profiles and calibration curves were established, enabling accurate quantification of transmitted joint forces. Additionally, the harvested signals demonstrated sufficient power output for wireless communication and potential onboard functionality, positioning the device as a self-sustained biomechanical monitor. This multifunctional platform represents a significant advancement in orthopedic implant technology, offering real-time, in vivo assessment of implant loading to support personalized rehabilitation strategies, early failure detection, and long-term postoperative care.

Traditional blood-based glucose detection methods are invasive, inconvenient, and unsuitable for continuous monitoring, highlighting the critical need for a non-invasive alternative. To address this urgent need, we developed a non-invasive and wearable electrochemical glucose sensor patch based on a platinum-copper (Pt-Cu) nanocomposite electrodeposited on carbon cloth thread (CCT) electrode after functionalizing with an electropolymerized polyphenol (Pphe)-glucose oxidase (GOx) film. The immobilization of GOx via the formation of a polyphenol film was done by electropolymerization of phenol in presence of GOx. The detection capability of the developed sensor was evaluated by chronoamperometry analysis and found that the sensor is able to detect glucose with wide linear detection range from 100 to 1500 μM with an ultra-low limit of detection (LOD) of 31.1 μM and 64.4 μM for artificial sweat and urine respectively. In addition, the developed sensor is found to be reproducible, repeatable and highly selective in presence of common interfering molecules present in the human samples. Furthermore, the developed sensor was seamlessly integrated into a wearable prototype device on a commercial bandage with custom made potentiostat circuit called Nanopot. The developed wearable prototype sensor system also exhibits a wide linear detection range from 300 to 1500 μM and a promising LOD of 25.8 μM. These results further validate the reliability, consistency, and practical applicability of the sensor system with a promising potential to address the urgent demand for non-invasive, painless and user-friendly diabetes management.

The motivation is to develop a device for pacemaker-implanted patients that would automatically alert them in an intense magnetic field. Moreover, the employees working near any strong magnetic environment would benefit by avoiding high exposure. This research delves into a comprehensive process for the implementation and characterization of such a wearable based on the magnetoresistance effect, which is a function of the magnetic field. The program executes on the Arduino IDE platform. Samples are taken for varying magnetic flux density along each axis, for changes in distance of 2.5 mm. The calculations take place accordingly and provide outputs in microtesla units. Subsequently, the device is analyzed by plotting the responses, and it also helps to understand the working procedure. For a certain axis, the magnetic field is generally stronger than others. The goal is to determine the highest absolute value at any instance, including the Earth's geomagnetic field of 22–67 μT. Regulatory standards are followed to divide the magnetic flux density into four states: power saver (below 150 μT), safe (150–500 μT), unsafe (500–750 μT), and danger (over 750 μT). These values consist of ±20 μT error, which is quite insignificant. Depending on the state, the novel device generates different warning signals to mitigate risk from magnetic fields. From the error bar plot, it is realized that the percentage of error decreases while calculating higher magnetic flux. The errors could be reduced remarkably by ensuring better calibration and compensation techniques in the future.

其动机是为植入心脏起搏器的患者开发一种装置，该装置可以在强磁场中自动提醒他们。此外，在任何强磁环境附近工作的员工都可以避免高暴露。本研究基于磁场的函数磁阻效应，对这种可穿戴设备的实现和表征进行了全面的研究。该程序在Arduino IDE平台上执行。沿着每条轴的不同磁通密度采集样品，距离变化为2.5 mm。计算相应地进行，并提供以微特斯拉为单位的输出。随后，通过绘制响应来分析设备，也有助于了解工作流程。对于某个轴，磁场通常比其他轴强。目标是确定在任何情况下的最高绝对值，包括22-67 μT的地球地磁场。根据法规标准，将磁通密度分为节能（低于150 μT）、安全（150 ~ 500 μT）、不安全（500 ~ 750 μT）和危险（超过750 μT）四种状态。这些值由±20 μT的误差组成，这是相当不显著的。根据不同的状态，这种新型装置会产生不同的警告信号，以减轻磁场带来的风险。从误差柱状图中可以看出，计算较高磁通时，误差百分比减小。通过确保未来更好的校准和补偿技术，可以显著减少误差。

The accurate differentiation of malaria stages is essential for effective treatment and epidemiological control. This work presents a theoretical analysis of a multilayer surface plasmon resonance (SPR) biosensor for malaria stage detection based on refractive index variations of infected red blood cells. The sensor combines silver, silicon nitride (Si₃N₄), monolayer molybdenum disulfide (MoS₂), and thiol-functionalized single-stranded DNA (ssDNA) on a BK7 prism. Using the transfer matrix method (TMM), we evaluate the sensor performance across Ring, Trophozoite, and Schizont stages through sensitivity, full width at half maximum (FWHM), quality factor (QF), detection accuracy (DA), limit of detection (LoD), and comprehensive sensitivity factor (CSF). The optimized configuration achieves angular sensitivities of 318.2 (Ring), 268.9 (Trophozoite), and 244.8 (Schizont) °/RIU, demonstrating clear stage discrimination and competitive performance compared to reported multilayer SPR sensors. The layered architecture was designed with experimentally accessible materials and configurations, supporting future translation to stage-specific diagnostic platforms.

Urine dipsticks are commonly used to detect pathological changes in urine due to their low cost and easy operation, having glucose parameter to detect glucosuria. Despite their advantages, the urine dipstick is ineffective in the early detection of diabetes due to its limitations in the detection of glucose below 100 mg/dl. Here, we present a novel, cost-effective ambient ring light-based smartphone platform to accurately estimate urinary glucose concentrations in lower points utilizing glucose sensors obtained from commercially available urine dipsticks (Mission® and Recombigen™). Glucose sensors changed color from green to brown with the increasing glucose concentration, resulting in a response time of 5 min. In this study, smartphone was used to capture images and analyze Red-Green-Blue (RGB) profiles, extracted with the help of an open-source smartphone-android-based Color Picker app. G intensity was determined to be inversely proportional and R/G intensity to be directly proportional to the increasing glucose concentration. LOD was found to be 6.2 and 24 mg/dl for Mission® glucose sensors with G and R/G respectively. On the other hand, Recombigen™ dipstick glucose sensors, LOD was evaluated as 5.8 and 16 mg/dl with G and R/G respectively. This smartphone-based assessment of glucose using dipsticks can be beneficial in the current screening and diagnostics sector of earlier detection of glucose in urine.

尿试纸成本低，操作方便，具有葡萄糖参数，可检测血糖，常用于检测尿液病理变化。尽管尿试纸有其优点，但由于其在检测葡萄糖低于100 mg/dl时的局限性，在糖尿病的早期检测中是无效的。在这里，我们提出了一种新颖的、具有成本效益的基于环境环光的智能手机平台，该平台利用从市售尿试纸（Mission®和Recombigen™）获得的葡萄糖传感器，准确估计低处的尿葡萄糖浓度。葡萄糖传感器的颜色随着葡萄糖浓度的增加从绿色变为棕色，导致响应时间为5分钟。在本研究中，使用智能手机捕获图像并分析红绿蓝（RGB）配置文件，并借助开源的基于智能手机android的color Picker应用程序提取。G强度被确定为反比，R/G强度与葡萄糖浓度的增加成正比。Mission®葡萄糖传感器的LOD分别为6.2和24 mg/dl，分别为G和R/G。另一方面，Recombigen™试纸式葡萄糖传感器的LOD分别以G和R/G计算为5.8和16 mg/dl。这种基于智能手机的葡萄糖评估使用试纸可以在当前的筛查和诊断领域早期检测尿液中的葡萄糖有益。

Simple method for monitoring the therapeutic efficient concentration of anti-histamine drug, bilastine (BIL), is essential for rationalizing allergy and respiratory therapy. Herein, an external redox-mediator free molecular trafficking approach was developed using conjugated oligosaccharide-polyphenol system, β-cyclodextrin-butein (BCD-Bt). Mechanism behind the molecular loading of BIL within the hydrophobic cavity of BCD simultaneously enabling the redox-active signal transduction from the conjugated Bt are explored using cyclic and differential pulse voltammetric analyses. BCD-Bt sensor platform exemplified the selective loading of analyte BIL with a reliable detection linearity (nm to μM, R² = 0.981) and limit feasible for salivary therapeutic drug monitoring. Synergistic optical absorbance and emission-based molecular trafficking test further complements the multi-modal functionality of the demonstrated BCD-Bt in other similar molecular assays.

监测抗组胺药物bilastine （BIL）治疗有效浓度的简单方法，对变态反应和呼吸治疗的合理化至关重要。本研究利用偶联低聚糖-多酚体系β-环糊精-丁蛋白（BCD-Bt）建立了一种无氧化还原介质的外部分子运输方法。利用循环和差分脉冲伏安分析探讨了BCD疏水腔内BIL分子负载的机制，同时使共轭Bt的氧化还原活性信号转导成为可能。BCD-Bt传感器平台可选择性负载分析物BIL，具有可靠的检测线性（nm ~ μM, R2 = 0.981）和可行的唾液治疗药物监测限。协同光学吸收和基于发射的分子运输测试进一步补充了BCD-Bt在其他类似分子分析中的多模态功能。

This paper introduces a novel bioelectromechanical device converting the electrochemical potential energy of excitable cells into mechanical work by coupling the Hodgkin–Huxley (HH) neuronal model response to a mechanical resonator. Addressing key challenges in bioelectromechanical systems, including biocompatibility, miniaturization, and efficient energy conversion, the device leverages the membrane potentials of biological cells to drive mechanical oscillations within microelectromechanical systems (MEMS). Through a combination of numerical simulations and theoretical analyses, it is demonstrated that the coupled HH–resonator system achieves stable limit cycles and significant mechanical displacements via parametric amplification. This amplification arises from the nonlinear capacitive coupling, which leads to Mathieu-like equations governing the system's dynamics, thereby enabling large oscillations from relatively small voltage inputs. Such parametric resonance is critical for the device's ability to sustain oscillatory motion, making it highly suitable for integration into compact and implantable MEMS applications. Potential applications include implantable sensors and actuators for real-time physiological monitoring, and advanced micro-scale systems that benefit from biologically sourced energy. The findings underscore the promise of bioelectromechanical systems in advancing biomedical and microengineering technologies, paving the way for innovative solutions in personalized medicine, bio-robotics, and beyond.

Post-endovascular aneurysm repair (EVAR) surveillance currently relies on routine imaging techniques such as computed tomography angiography and magnetic resonance angiography, which expose patients to radiation, nephrotoxic contrast agents, and place logistical burdens on healthcare systems. This review critically examines the potential of implantable sensors, particularly pressure-monitoring systems, to provide continuous, minimally invasive post-EVAR surveillance. We present an overview of the biological and biomechanical rationale for monitoring aneurysm sac pressurization, analyze existing sensor technologies including EndoSure® and ImPressure®, and discuss technical challenges such as wireless telemetry, biocompatibility, signal attenuation, and power management. Regulatory milestones and alignment with ESVS and SVS surveillance guidelines are reviewed, along with the current evidence gap between pressure trends and clinical outcomes such as reintervention or rupture. While technical feasibility has been demonstrated in controlled settings, no studies to date have shown that pressure monitoring improves long-term outcomes or guides decision-making independently of imaging. The limitations of pressure-based monitoring are discussed alongside emerging sensor designs that integrate pressure, morphological, and biochemical sensing. This review concludes that implantable pressure sensors remain investigational tools whose clinical adoption will depend on future trials demonstrating diagnostic accuracy, patient acceptability, cost-effectiveness, and outcome benefit.

血管内动脉瘤修复后（EVAR）监测目前依赖于常规成像技术，如计算机断层血管造影和磁共振血管造影，这使患者暴露于辐射、肾毒性造影剂，并给医疗系统带来后勤负担。这篇综述严格审查了植入式传感器的潜力，特别是压力监测系统，以提供持续的、微创的evar后监测。我们概述了监测动脉瘤囊加压的生物学和生物力学原理，分析了现有的传感器技术，包括EndoSure®和ImPressure®，并讨论了无线遥测、生物相容性、信号衰减和电源管理等技术挑战。审查了监管里程碑和与ESVS和SVS监测指南的一致性，以及当前压力趋势与临床结果（如再干预或破裂）之间的证据差距。虽然技术上的可行性已经在受控环境下得到了证明，但迄今为止还没有研究表明压力监测可以改善长期结果或独立于成像指导决策。本文讨论了基于压力的监测的局限性以及集成压力、形态和生化传感的新兴传感器设计。本综述的结论是，植入式压力传感器仍然是研究工具，其临床采用将取决于未来的试验，以证明诊断的准确性、患者的可接受性、成本效益和结局效益。
