Sometimes, smaller size is not always better, and looking for nanomaterials that offer better device performance requires consideration of their properties at the first stage. In this study, effects polyethylenimine-capped AuNPs (PEI-AuNPs) proteins on immunosensor performances, namely, sensitivity limit detection, are examined. The size-effect investigation PEI-AuNPs involves modification surface disposable screen-printed carbon electrodes to support primary antibodies ability load...
Colorimetric sensors are a promising technique for the simple screening of water, food, and environmental samples contaminated with interferents, allowing color changes to be observed naked eye or spectrophotometer. In this study, colorimetric sensor selective detection hexavalent chromium ion (Cr(VI)) contamination in water was developed. A combination sodium borohydride-coated gold citrate-capped silver nanoparticles (Na-AuNPs/cit-AgNPs) employed as probe. Upon addition Cr(VI)-contaminated...
A plasmonic Au–Ag alloy fabric substrate is developed via in situ self-assembly of NPs on muslin fabric. An appropriate molar ratio Au and Ag type are proved to be key factors for selective detection ampicillin.
In this work, a novel electrochemical sensor was proposed for the simultaneous determination of fat-soluble vitamins (A, D, E, K) using screen-printed graphene/Nafion electrode (SPGNE). The scanning electron microscopy used morphological characterization surface. behaviors have been studied in mixture ethanol and sodium perchlorate monohydrate square-wave voltammetry (SWV). results obtained indicated that oxidation peak each vitamin appeared at different potentials leading to possibility...
A simple and reproducible surface enhanced Raman scattering (SERS) substrate of bimetallic gold–silver (Au–Ag) based on discarded a Blu-ray disc read only memory (BD-ROM) was developed by simply incorporating electrochemical (EC) treatment chemical reaction. The resurfaced AgBD-ROM (r-AgBD-ROM) fabricated EC Ag film layer in BD-ROM (AgBD-ROM) to generate silver nanoparticles (AgNPs) the indented pattern surface. Then, galvanic displacement reaction Au carried out prepare Au–Ag structure...
Abstract Nanosphere lithography is employed to simply fabricate metallic hexagonal nanohole array based on metal deposition within interstices of the nanospheres. In contrast, fabrication nanodisc (inverted pattern array) unavoidably includes an additional step creating a patterned resist layer or use high‐resolution techniques. this work, facile method named “plasma‐etched nanosphere conductivity‐inverted (PENCIL)” developed gold disc arrays indium tin oxide (ITO)‐coated glass by...
The development of 3-hydroxybutyric acid (3-HB) biosensors via electrochemical method is commonly based on the use enzymes that usually display inherent instability. Here, a novel non-enzymatic 3-HB sensor platform by incorporating manganese oxide nanoparticles (Mn 2 O 3 NPs) modified screen printed carbon electrode (SPCE) and sodium nitroprusside (SNP) electrolyte was reported for first time. mechanism this formation electroactive SNP-HB species with assistance Mn catalyst. By enhanced...
A novel developed non-enzymatic electrochemical sensor was designed for the detection of lactic acid (LA) in perishable products, with a focus on monitoring milk spoilage. The utilizes hybrid copper-based electrode consisting cuprous oxide (Cu 2 O), copper (CuO), and hydroxide (Cu(OH) ), which collectively contribute to enhanced performance through their synergistic effects. Cyclic voltammetric studies revealed distinct oxidation peaks associated LA detection, highlighting superior catalytic...
A recent study conducted in Khon Kaen Province, Thailand, evaluated the effectiveness of a technology-assisted intervention aimed at improving water quality and addressing related health issues communities around key bodies. The targeted concerns associated with contamination, including chronic kidney diseases, skin conditions, hypertension, neurological symptoms. included assessments evaluations 586 residents implemented Learning Innovation Platform (LIP) across 13 communities. Results...
A long history about milk adulteration with hydrogen peroxide (H2O2) is extensively reported in worldwide. According to fast degradation of H2O2 raw cow milk, the detection very challenging. In this study, a highly sensitive non-enzymatic electrochemical sensor has been developed for detecting adulterated milk. The bimetallic gold-platinum nanoparticles (AuPt NPs) are used as electrocatalysts selectively enhance signal H2O2. screen-printed carbon electrode (SPCE) modified proper Au:Pt molar...
