Here, an approach based on electronic sensing of viral RNA is proposed for both virus detection and variant tracking. The sensing strategy of the Organic Charge-Modulated Field-Effect Transistor (OCMFET) is employed for the development of a multi-sensing platform, capable of parallel evaluation of control references and investigated samples. PCR-free detection of viral genomic RNA is demonstrated at different target concentrations, with optimal discrimination with respect to negative control. Moreover, the same approach is feasible for virus variant tracking, as a screening strategy for mutation detection in PCR-amplified samples: the approach can be used for a rationalization of RNA sequencing procedures, which are difficult to perform in the acute phases of pandemics, but are fundamental for an effective pandemic management. The results pave the way for novel strategies to enhance cost-effectiveness, easiness-of-use in combination with selectivity and sensitivity in virus detection during severe pandemic conditions, and a more effective variant tracking by optimizing the access to sequencing resources even during the acute phases of pandemic.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"4 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.70000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273230","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}

Nanoscale field-effect transistors (FETs) modified with target-specific receptors enable direct target sensing, offering enhanced sensitivity due to nanoscale channel confinement. In this regard, single-walled carbon nanotubes (SWCNTs) have emerged as strong candidates for the development of transistor-based biosensors. Understanding the structural parameters that affect sensing performance in such nanoscale electrical detection platforms is essential for their reliable and controllable use. Here, this is investigated that how different assembly strategies employed in the construction of nanoscale aptamer-based SWCNT-FET biosensors can dramatically affect their signal generation, with conductance increasing or decreasing for the same aptamer-cortisol recognition event. a cortisol-binding DNA aptamer exhibiting well-characterized conformational behavior is employed, as a model receptor to explore the influence of different surface functionalization strategies on SWCNT-based biosensors performance. Through combined electrical and optical characterization, this is elucidated that how aptamer conformation governs local electrostatic changes within the Debye length, which in turn modulates the electrostatic gating of the devices. This work offers insight into effective design strategies for the construction of biosensors functionalized with electrostatically active molecular receptors.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"4 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.70002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273374","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, these systems still face challenges related to the continuous monitoring of critical bioprocess parameters, in particular, because sensor integration is often difficult, and sample volumes for offline measurements are limited. In this work, a novel 3D-printed microfluidic lab-on-a-chip sensor platform is presented, specifically designed to be compatible with a range of cultivation systems (including shake flasks, bioreactors, and custom microbioreactors). The microfluidic system acts as a miniaturized bypass, integrating sensors for real-time monitoring of key bioprocess parameters (such as pH, pO₂, pCO₂, glucose, and lactate) without compromising culture volume. This system has been successfully applied in a proof-of-concept for the cultivation of Escherichia coli and Saccharomyces cerevisiae. In addition, this platform also includes an integrated sampling unit for small-volume collection, thereby potentially enabling the analysis of complex analyte mixtures such as amino acids or recombinant proteins. The presented system thus represents a valuable tool for both real-time online monitoring and offline analysis, contributing to the optimization of biopharmaceutical production processes.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"4 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.70001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273307","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}

Among various moisture-absorbing materials, 2D materials are potential contestants for fabricating humidity sensors owing to their fascinating ultra-high surface-to-volume ratio, abundant active sites, and large carrier mobilities. In this work, vanadium pentoxide (V2O5) nanofibers (NFs) produced by a facile electrospinning method using VO(acac)2 10% Polyacrylonitrile/Dimethylformamid are showcased for humidity sensing. The annealing temperature-dependent (400–600 °C) variations in morphology and composition of the electrospun V2O5 NFs are studied by structural and physicochemical characterization methods. Subsequently, the V2O5 NFs are effectively used for humidity sensing at room temperature (RT). It is demonstrated that the optimum RT humidity response and sensitivity of the NF sensor are obtained at an annealing temperature of 500 °C with a high surface area of 14.8 m2g−1 containing large porous fibers ranging from 200 to 500 nm diameter. The synthesized V2O5 NF sensor exhibits high sensitivity to water at RT (max. 1.427 at 90 %RH), excellent linearity, wide range (10–90%RH), and quick response and recovery times. This work sets a benchmark for designing novel V2O5-based RT humidity sensing devices.","PeriodicalId":100037,"journal":{"name":"Advanced Sensor Research","volume":"4 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsr.202500040","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273212","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}
