While DNA-based probes have been commonly used in electrochemical biosensors owing to their label-free operation, low cost, and sensitivity, their susceptibility to enzymatic degradation and low thermal stability has limited their broader utility. As an alternative, peptide nucleic acid (PNA) probes have gained increasing attention due to their synthetic backbone, which is based on an electrically neutral N-(2-aminoethyl)glycine (AEG) structure. This neutrality confers high resistance to nucleases and polymerases, while enabling stronger and more stable hybridization with negatively charged DNA targets. PNA probes also maintain structural integrity under low ionic strength conditions, improving signal stability compared to conventional DNA probes. These advantages have led to a growing body of research exploring PNA-based biosensors for portable applications. This mini-review surveys recent developments in this area, focusing on the physicochemical properties of PNA and their implications for biosensor design.

While measuring metabolic outputs like short-chain fatty acids (SCFAs) in stool or blood provide insights into microbial metabolism, sampling frequency is severely limited, preventing observation of the temporal dynamics of how gut microbes respond to dietary inputs and environmental changes on an hour-by-hour basis. Hydrogen gas, produced by gut microbial metabolism, represents an underutilized biomarker for continuous monitoring of microbial metabolic activity. Following its production, hydrogen is expelled through two major routes: breath and flatus, with flatus containing dramatically higher hydrogen concentrations compared to breath, making it an ideal target for sensitive detection. Currently, no tools exist for continuous, non-invasive monitoring of hydrogen in flatus to track changes in gut microbial metabolism. To address this gap, we developed the Smart Underwear, the first wearable device that continuously measures hydrogen gas expelled in flatus, providing unprecedented temporal resolution of gut microbial activity. In a week-long User Experience Study, the Smart Underwear successfully tracked hydrogen in flatus with participants reporting high comfort and compliance. In a second study, the Smart Underwear accurately detected increased hydrogen production following inulin ingestion with 94.7 % sensitivity in 38 healthy participants, demonstrating its capability to track diet-induced changes in microbial metabolism. This novel platform enables longitudinal studies of microbiome function, capturing both inter-individual differences and intra-individual temporal dynamics, while opening new avenues for investigating diet-microbiome interactions, circadian patterns, and the functional consequences of changes in microbial composition.</div></div>","PeriodicalId":260,"journal":{"name":"Biosensors and Bioelectronics: X","volume":"27 ","pages":"Article 100699"},"PeriodicalIF":10.61,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145321016","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}

Comparative analysis highlights substantial differences in analytical sensitivity, turnaround times, cost-effectiveness, and deployment logistics between isothermal amplification, RT-PCR-based, and immunochromatographic assays.

The insole integrates multiple identical triboelectric energy harvesters strategically positioned to capture electrical signals generated from ground reaction forces during daily activities such as walking, jogging, and running. Proof-of-concept testing was conducted on a single participant under two conditions: a healthy foot and a simulated flatfoot created by reducing the medial arch height by approximately 70%. In the healthy foot trials, the system demonstrated consistent and reliable performance, with negligible electrical output from the medial arch sensor due to minimal ground contact in this region. In contrast, the simulated flatfoot condition produced a significant increase in voltage output from the medial arch sensor, successfully identifying the abnormal foot mechanics associated with arch collapse. Additionally, a neural network was implemented to classify healthy and flatfoot conditions from the collected data, achieving an accuracy of 86% and a precision of 96%, demonstrating the feasibility of machine learning integration for automated flatfoot detection. Overall, the findings validate the smart insole’s capability as a promising tool for continuous foot health monitoring, early diagnosis of flatfoot, and future applications in personalized rehabilitation and preventative care.</div></div>","PeriodicalId":260,"journal":{"name":"Biosensors and Bioelectronics: X","volume":"26 ","pages":"Article 100649"},"PeriodicalIF":10.61,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144580058","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}
