The traditional methods for the detection of adulterants in milk products are experiencing more difficulties due to their poor selectivity, sensitivity, and unsuitability for complex matrices. The researchers are paying close attention to nanomaterial based sensing systems, which are seen to be among the most effective alternatives to the traditional approaches.

Presence of incompletely metabolized antibiotics in water bodies, leads to their entry into food chain via live stock and serve as a severe threat to human health. Hence it is imperative that the antibiotics are detected at the source itself. Aminoglycosides are broad spectrum antibiotics known to be more toxic and resistant to multidrug resistant (MDR) organisms compared to other classes of antibiotics. Accordingly in the present work a selective, sensitive and low-cost detection technique for aminoglycoside based antibiotics has been developed. An iron-dependent lipid peroxidation has been explored for the first time to develop a rapid and sensitive colorimetric assay for detecting aminoglycoside antibiotics. A lab-on-chip model (LoC) was designed and developed to miniaturize the colorimetric assay based model for its applications in the real-time analysis of antibiotics. The LoC was integrated with optical fibers, electronic components and associated signal processing circuitry to construct a portable device for antibiotic quantification. Interestingly a selective response towards gentamicin amongst the tested antibiotic was observed. The formation of a colored product within five minutes of reaction time enables a swift and less cumbersome analysis and compared to existing sophisticated analytical techniques. The detection method was validated for gentamicin spiked environmental samples and showed a recovery of more than 90%. This method can serve as a suitable alternative in limited laboratory setups and provides a generic platform for developing a rapid, user-friendly and economical detection methods for environmental monitoring of antibiotics.</div>","PeriodicalId":426,"journal":{"name":"Sensors and Actuators Reports","volume":"5 ","pages":"Article 100151"},"PeriodicalIF":5.9,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2378380","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}

Nowadays, different wearable sensors are available but they usually lack comfort for continuous use during normal daily life activities. In this study, new graphene-based flexible dry electrodes are investigated to overcome the limitations of the currently available electrodes. Briefly, they are realized through casting PVDF (polyvinylidene fluoride)/GNP (graphene nanoplatelets) nanocomposite over commercial textiles. These electrodes are soft and flexible and adhere more easily to the skin. In terms of performance, the PVDF/GNP electrodes show lower impedance per unit area compared to commercial ones, hence they can be employed for biosignal detection. In particular, the developed electrodes are used for electrocardiogram (ECG) signal monitoring. The recorded ECG signal-to-noise ratio (SNR) reached up to 40 dB and all necessary ECG signal features and intervals are clearly distinguishable. Furthermore, the essential ECG signal intervals on each cadiac cycle show very small variations in time. Finally, the superhydrophobic property allows the electrodes to be used repeatedly after washing. As a final note, the developed dry PVDF/GNP electrodes provide reusability, biocompatibility, good skin-electrode contact, and no signs of skin irritation.</div>","PeriodicalId":426,"journal":{"name":"Sensors and Actuators Reports","volume":"5 ","pages":"Article 100161"},"PeriodicalIF":5.9,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2892072","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}

Current emergent requirements for TG sensing include the development of electrochemical sensors for easy, cost-effective, disposable and single use triglyceride sensors. We propose a TG sensor using an engineered glycerol 3-phosphate oxidase (GlpO) and electrochemical detection. In this study, we aimed to develop an electrochemical TG sensor based on engineering the oxidative half reaction of GlpO to be oxygen insensitive, with the employment of an interdigitated electrode (IDE). To construct an oxygen insensitive mutant GlpO, we constructed a double mutant, Met104Phe/Asp169Glu, which revealed an engineered GlpO exhibiting repressed oxidase activity, while its dye-mediated dehydrogenase activity enhanced. The electrochemical enzyme sensor was constructed for the measurement of TG based on engineered GlpO using disposable screen-printed carbon electrode (SPCE) or disposable IDE using Ru complex as the electron mediator. By using the disposable IDE sensor, a highly sensitive electrochemical sensor for Glp was achieved, with the sensitivity of 0.4 µA/mM. The improved sensitivity was 2.4 times higher than that of SPCE (0.17 µA/mM), with LOD of 0.022 mM. Furthermore, the dry sensor strip, where the double mutant GlpO and Ru complex were dropcasted and dried on the IDE, was prepared and the Glp concentration was successfully measured in the delipidized serum solution. Therefore, by the employment of the established pretreatment method for TG to release Glp, a highly sensitive, accurate, easy and rapid electrochemical measurement method for TG will be developed using constructed M104F/D169E mutant GlpO with the combination of IDE.</div>","PeriodicalId":426,"journal":{"name":"Sensors and Actuators Reports","volume":"5 ","pages":"Article 100164"},"PeriodicalIF":5.9,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3209850","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}
