Surface plasmon resonance (SPR) acts as an effective light antenna for signal transduction in these sensors. Traditionally, plasmon-mediated PEC sensors operate via hot carrier injection, which necessitates direct contact between the plasmonic antenna and the semiconductor, thereby limiting sensor design flexibility. In this work, we introduce plasmon-induced resonance energy transfer (PIRET) as a novel signal transduction mechanism in a PEC immunosensor. A Bi3FeMo2O12 (BFMO) semiconductor thin film is functionalized with capture antibodies, while plasmonic Au nanoparticles with absorption spectrum overlapping with BFMO are conjugated to detection antibodies. Upon target antigen binding, the Au nanoparticles are positioned in proximity to the BFMO surface through a sandwich immunoassay configuration, enabling PIRET-mediated generation of electron-hole pairs in BFMO. Using human IgG as a model analyte, we demonstrate the feasibility and advantages of PIRET, highlighting its potential to extend PEC sensor design by permitting a physical gap between the plasmonic antenna and semiconductor.","PeriodicalId":72870,"journal":{"name":"ECS sensors plus","volume":"5 2","pages":"021603"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13276971/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148297561","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}

Also, micro-electronics hardly embeds chemical functionalities on silicon, as soft materials suffer from harsh conditions of conventional processes. In this study, electrochemistry on a chip is investigated to pattern conductivity-based measurement devices at small scale via electropolymerization. To comply with additive manufacturing, a dewetting coating and local quasi-reference/counter micro-electrodes shall be integrated on each chip. The process reliability is challenged using minimalist chemical and energy resources, such that a μ L droplet of an electro-active solution composed mostly of a non-toxic and affordable solvent suffices to coat 16 elements on a 3×3 mm 2 chip. Despite the complexity of electrochemistry at such scales, the coatings variability is dominated by the chemical composition of the droplet. Avoiding a vessel to confine large volumes of solutions and integrating all electrodes is required to reduce drastically the electrochemical signal noise. This demonstrates its sufficient stability to screen conducting polymer materials when their precursors are not available in large amount to be coated with conventional techniques. It also demonstrates its compliance for chips microfabrication using conducting polymers as functional materials for electrochemically-assisted additive manufacturing production.","PeriodicalId":72870,"journal":{"name":"ECS sensors plus","volume":"4 4","pages":"044401-044401"},"PeriodicalIF":0.0,"publicationDate":"2025-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147910760","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}

While previous studies have successfully demonstrated in vivo molecular monitoring using E-AB sensors, they typically rely on custom-built probes fabricated through manual, labor-intensive processes. Constructing such probes requires substantial time, technical expertise, and precision, creating a high barrier to entry for researchers interested in the field of in vivo measurements. To address this limitation, we present an alternative fabrication approach that combines established device construction methods with rapid prototyping via additive manufacturing (i.e., stereolithography). This platform enables continuous molecular monitoring in the subcutaneous interstitial fluid (ISF) of rodent models. We selected ISF as a target fluid due to its growing recognition as a promising frontier for continuous molecular monitoring and its central role in current biosensor research. Our goal is to eliminate the most prohibitive steps in traditional fabrication, thereby reducing the skill threshold required for building functional E-AB probes. By improving the construction process, our methods should make the technology more easily adoptable by a broader range of research laboratories. Ultimately, we aim to broaden the use of E-AB sensors and accelerate development in the field of real-time, in vivo molecular monitoring.","PeriodicalId":72870,"journal":{"name":"ECS sensors plus","volume":"4 3","pages":"037001"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13192993/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148019010","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}

It is essential to have affordable and easy access to remote biomedical measurements. This makes flexible sensors a more attractive choice owing to their high sensitivity and flexibility along with low cost and ease of use. As an additional advantage, 3D printing has become increasingly popular in areas such as biomedicine, environment, and industry. This study demonstrates 3D-printed flexible sensors for tactile sensing. A biocompatible silicone elastomer such as polydimethylsiloxane (PDMS) with low elastic modulus and high stretchability makes an excellent wearable sensor material. Incorporating CNTs at varying concentrations (0.5, 1, 2)wt% enhances the sensor’s mechanical strength, conductivity, and responsiveness to mechanical strain. In addition to enhancing the thermal stability of the composite by 44%, multi-walled carbon nanotubes (MWCNTs) also enhanced the breaking strength by 57% with a 2 wt% CNT loading. Moreover, the contact angle values improved by 15%, making it a biomedical-grade hydrophobic surface. The electrical characteristics of these sensors reveal excellent strain sensitivity, making them perfect for monitoring finger movements and biomedical measurements. Overall, 2 wt% CNT-PDMS sensors exhibit optimal performance, paving the way for advanced tactile sensing in biomedical and industrial settings.","PeriodicalId":72870,"journal":{"name":"ECS sensors plus","volume":"354 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141380857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep learning is showing promising results in automating the process of quantifying the percentage of damage using the assay images. But the lack of large datasets and imbalanced data is a challenge. In this study, synthetic comet assay images generated from simple geometric shapes were used to augment the data for training the Convolutional Neural Network. The results from the model trained using the augmented data were compared with the results from a model trained exclusively on real images. It was observed that the use of synthetic data in training not only gave a significantly better coefficient of determination (R2), but also resulted in a more robust model i.e., with less variation in R2 compared to training without synthetic data. This approach can lead to improved training while using a smaller training dataset, saving cost and effort involved in capturing additional experimental images and annotating them. Additional benefits include addressing imbalanced datasets, and data privacy concerns. Similar approaches must be explored in other low data domains to extract the same benefits.","PeriodicalId":72870,"journal":{"name":"ECS sensors plus","volume":"64 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139600416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
