In this study, it is demonstrated that by monitoring the conductance of two different functional hydrogels, the concentrations of two different drugs in aqueous solution can be selectively and quantitatively measured simultaneously based on non-specific interactions. Detailed characterization of the competitive drug adsorption on the hydrogels allows the description of both hydrogel conductances as a function of the drug concentrations based on physical models. The result is a system of non-linear equations that can be solved for the drug concentrations. The different affinities and conductance responses of the hydrogels for the two drugs is a prerequisite, which is usually achieved with different materials. This approach is demonstrated with hydrogels based on poly(ethylene glycol), functionalized with the ionic monomers [2-(acryloyloxy)ethyl] trimethylammonium chloride (AETA) and 3-sulfopropyl acrylate potassium salt (SPA), and the drugs diclofenac and metoprolol. The hydrogel conductance is found to be linear with drug concentration in the hydrogels, which in turn is described by a non-linear Langmuir-type competitive adsorption isotherm. The proposed approach thus shows potential for future studies on more complex mixtures by including a larger variety of functional hydrogels.</p>","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"4 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.202400141","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tremendous advancements in filtration and purification materials have occurred in recent years, particularly with the advent of multifunctional, high-surface-area materials. Despite these, a significant challenge remains for canisters, and that is knowing when, without a doubt, they should be replaced. Residual lifetime indicators (RLIs) are essential for informing wearers when to make an active decision to replace their canister. RLIs can also be used to inform policymakers of appropriate changeover schedules, thereby reducing the wearer's risk of becoming exposed to airborne contaminants. This paper discusses some of the challenges with current changeover approaches and examines key issues for incorporating RLIs into canister respirators. A variety of sensor technologies and methodologies are examined, along with some recent RLI developments in the research and patent literature. A discussion on the challenges for making RLIs more amenable for incorporation into canisters is provided, along with recommendations for future development.</p>","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"4 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.202400029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143380022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional methods encounter scalability and energy efficiency challenges. To overcome these, Triboelectric Nanogenerators (TENG) are explored for energy harvesting, particularly in live-streaming sound monitoring systems. This study introduces a sustainable methodology integrating TENG-based sensors into live sound monitoring pipelines, enhancing energy-efficient sound classification and captioning by model selection and fine-tuning strategies. Our cost-effective TENG sensor harvests ambient sound vibrations and background noise, producing up to 1.2 <i>µ</i>W cm<sup>−2</sup> output power and successfully charging capacitors. This shows its capability for sustainable energy harvesting. The system achieves 94.3% classification accuracy using the Hierarchical Token Semantic Audio Transformer (HTS-AT) model identified as optimal for live sound event monitoring. Additionally, continuous audio captioning using the EnCodec Combining Neural Audio Codec and Audio-Text Joint Embedding for Automated Audio Captioning model (EnCLAP) showcases rapid and precise processing capabilities that are suitable for live-streaming environments. The Bidirectional Encoder representation from the Audio Transformers (BEATs) model also demonstrated exceptional performance, achieving an accuracy of 97.25%. These models were fine-tuned using the TENG-recorded ESC-50 dataset, ensuring the system's adaptability to diverse sound conditions.

These tools may also be useful for screening samples at blood donation centers to avert potential new infections. The current benchmark method to support antiretroviral drug monitoring, liquid chromatography coupled to mass spectrometry (LC-MS), requires centralized facilities with costly instrumentation, and has blood-to-result turnaround times of days to weeks, making it impractical for effective drug monitoring. Seeking to overcome this issue, an aptamer is developed for the antiretroviral drug emtricitabine, which is present in most antiretroviral combination therapies in the market and used for both infection management and prevention. The aptamer has clinically relevant sensitivity in biofluids and is highly selective relative to close analogs such as cytosine, cytidine, fluorocytidine, and lamivudine (a.k.a. 3TC). Using this aptamer, two analytical assays are developed, one for continuous, in-vivo emtricitabine monitoring in rodent research models, and one for rapid and high-throughput screening of emtricitabine levels in human plasma.
