In tandem with the R5-mCherry-Bst this RT construct completes the enzyme set required for RT-LAMP mediated detection of Dengue. The introduction of the thermophilic green fluorescence protein TGP, allowed a heat purification step at 95 °C to be introduced into the workflow, simplifying purification. A 3 terminal amino acid (SSK) truncation of the naturally occurring silaffin R5 binding peptide (Δ3R5) enabled improved protein purification and loading on silica and good storage stabilisation (≥3 months). L-arginine triggered elution of enzyme from silica, immediately prior to use, enabled a soluble enzyme to be delivered directly into the RT-LAMP reactions, producing a clear solution and compatibility with turbidity detection of PPi released complexes that form insoluble Mg<sub>2</sub>P<sub>2</sub>O<sub>7</sub>. A unique primer set was designed for the detection of Dengue Serotype 1 RNA, using a primer set (CAB 3), targeting the RNA-dependent RNA polymerase (RdRp), part of the NS5 region. This was chosen to minimise primer dimer formation, thereby reducing false positives. Amplification was achieved with high sensitivity (10 copies), with turbidity analysis able to distinguish positive and negative reactions. The approach developed has the potential to widen the application of LAMP diagnostics for neglected diseases such as Dengue by removing the availability of biological reagents as a limiting factor.</p>","PeriodicalId":64,"journal":{"name":"Analytical Methods","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synergistic effect of polyimide (PI) doped silver nanowires (AgNWs) improved the selectivity and sensitivity of the fabricated sensor. First, the AgNWs were prepared by the polyol process, and then composited with PI to obtain the target composite. Subsequently, the composite was characterized in detail and was used to modify a GCE for the NP detection. Afterwards, electrochemical measurements were performed for simultaneous detection of three NPs. Under optimal conditions, the results showed that the linear detection ranges were 1-400 μM for 4-nitrophenol (4-NP) and 1-350 μM for both 2-nitrophenol (2-NP) and 3-nitrophenol (3-NP) and the limits of detection (LODs) were 0.081 μM for 2-NP, 0.107 μM for 3-NP, and 0.063 μM for 4-NP, respectively. In addition, the fabricated electrode exhibited excellent reproducibility (RSDs of 2.85% for 2-NP, 2.71% for 3-NP, and 1.80% for 4-NP, respectively) and stability (RSDs of 6.17% for 2-NP, 2.36% for 3-NP, and 3.89% for 4-NP, respectively) over multiple measurements. Moreover, the sensor showed excellent anti-interference capability and was successfully applied to detect NP analytes in real water samples with recoveries ranging from 91.10% to 109.00%.
