Surface plasmon resonance (SPR) biosensors provide a reliable, label-free method for highly sensitive detection of food adulterants. In this study, we present a novel gallium sulfide (GaS)-immobilized optical fiber SPR sensor designed for the rapid, real-time detection of BB synthetic dye. The proposed sensor is comprised of a high birefringence layer (HBL) core with non-added formaldehyde (NaF) cladding, silver (Ag) as the plasmonic metal, and GaS for enhanced detection sensitivity. To determine the sensor performance, the wavelength-dependent response was measured at different refractive indices (RIs), together with sensitivity and figure of merit (FOM) over the wavelength range of 400 nm to 1000 nm. The parameters were evaluated in a sensing medium consisting of water and BB under concentrations ranging from 10 mM to 600 mM. Moreover, the distribution of electromagnetic fields across the multilayer structures of the sensor, particularly at the interfaces between Ag-GaS and GaS-analytes, was investigated. At a 10 mM concentration, the optimized Ag-GaS-based sensor, consisting of 70 nm Ag and 3 nm GaS layers at an incidence angle of 85°, achieves a maximum sensitivity of 5119.6 nm/RIU and FOM of 255.98 RIU\u0000-1\u0000. The obtained results illustrate the sensor has the potential to detect non-approved colors like BB in food items with great sensitivity and accuracy.","PeriodicalId":446,"journal":{"name":"IEEE Open Journal of Nanotechnology","volume":"5 ","pages":"98-106"},"PeriodicalIF":1.8,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10726679","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672081","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}

Effective monitoring of zinc nitrate contamination is essential to protect aquatic ecosystems and also ensures the safety of aquaculture products. This study presents a bismuth-immobilized optical fiber-based surface plasmon resonance (SPR) biosensor for the rapid detection of zinc nitrate contamination. The sensor design incorporates a ZBLAN core, NaF cladding, silver (Ag) as a plasmonic metal, and bismuth (Bi) to enhance detection sensitivity. In our work, we compared the sensor performance of the proposed bismuth-immobilized SPR biosensor with the conventional Ag-based sensor design. The performance of the proposed Ag-Bi sensor model is compared with the conventional Ag-based sensor. To improve the sensitivity and FOM, Ag layer thickness is varied between 50 and 80 nm with respect to the zinc nitrate concentrations of 0%, 1%, and 5%. Using the angular interrogation method, the resonance wavelength shifts are correlated to changes in refractive index (RI). The Bi-immobilized Ag layer achieved a maximum sensitivity of 5680 nm/RIU at 5% zinc nitrate concentration and an FOM of 95.2381 RIU\u0000−1\u0000 at 1%. While conventional Ag-based sensors attained a maximum sensitivity of 5240 nm/RIU and an FOM of 90.345 RIU\u0000−1\u0000 at 80 nm Ag thickness. The above results demonstrate that the Ag-Bi layer SPR biosensor is highly suitable for simultaneously detecting zinc nitrate and other heavy metal contaminants in water, providing a cost-effective solution for heavy metal contamination detection in aquatic industry.","PeriodicalId":446,"journal":{"name":"IEEE Open Journal of Nanotechnology","volume":"5 ","pages":"80-88"},"PeriodicalIF":1.8,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10715639","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595070","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}

In the design and fabrication of the sequencing device, carbon-based nanomaterials such as graphene have been explored as a promising sensing material that provides an excellent combination of spatial resolution and base specificity. Using first-principles simulation, we determined the effect on the electrical conductivity of a one-dimensional carbon chain due to the presence of four DNA bases. The simulation results indicate that the interaction between the carbon chain and different DNA bases leads to different levels of conductivity change in the carbon chain. Quantitatively, base A is the most difficult base to detect due to its relatively small current change. Furthermore, the results also show that the relative orientation of the bases with respect to the carbon chain can affect the induced current change in the chain. This information can be used to optimize the structural design of future sequencing devices. Collectively, the first-principles simulation results suggest the integration of a one-dimensional carbon chain with supporting nanofluidic designs can provide a viable approach towards the development of a compact, robust, and high-resolution DNA sequencing system.","PeriodicalId":446,"journal":{"name":"IEEE Open Journal of Nanotechnology","volume":"5 ","pages":"39-46"},"PeriodicalIF":1.8,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10663936","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224300","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}

The proposed RNG design leverages the inherent randomness between each bit of data to generate larger sets of random numbers by concatenating the modules of the customized linear feedback shift registers. To efficiently generate random data, a plane of RNGs (comprising of multiple modules) is introduced. A sliding window approach is employed for reading data in both the horizontal and vertical directions; therefore, the sets of random numbers are generated by doubling the datasets and inverting the duplicated datasets. Flip-Flops are utilized to isolate the datasets and diminish correlation among them. This paper explores variations in parameters to evaluate their impact on the performance of the proposed design. A comparative analysis between the proposed design and existing SNG designs from technical literature is presented.

This study investigates the development of Ion Sensitive Field Effect Transistor (ISFET) sensors for DNA-based blood cancer diagnosis. This work presents the design of a two-dimensional ion-sensitive field-effect transistor. Concentration fluctuations and transfer characteristics with different oxides are studied using blood from two electrolyte solutions. It is possible to evaluate how the modeled device can be utilized as a pH sensor or a biosensor in healthcare applications by looking at how the pH changes for different oxides. Additionally, several oxides were examined in the simulated ISFET devices' output characteristics. Blood is the electrolyte to study the device's sensitivity for different oxides. When pH 7.4 is considered, SiO\u00002\u0000 oxide is significantly more sensitive than other oxides. The resulting 2D-ISFET exhibits remarkable blood electrolyte sensitivity and holds potential as a quick detection tool for blood cancer. The results show that the ISFET possesses drain-induced barrier lowering (DIBL), greater ON-current \u0000<italic>(ION\u0000) and switching ratio (\u0000<italic>ION/IOFF\u0000), and decreased subthreshold swing (SS). The pH sensor's sensitivity and the suggested equipment can detect up to 30 fg/mL of blood cancer biomarkers.
