Evaluation of extracellular domain human epidermal growth factor receptor-2 (HER2-ECD) oncomarker status is an impressive in screening, diagnosing and monitoring early-stage breast cancer (BC). Electrochemical aptamer-based nanobiosensor with high sensitivity selectivity for quantitative qualitative measurement HER2-ECD was developed. In this study, the nanocomposite made by distinct materials included reduced graphene oxide nano-sheets (rGONs) rhodium nanoparticles (Rh-NPs) on graphite electrode (GE) surface. This structure resulted amplified electrochemical activity, surface area, stability, bio-compatibility. Each steps preparing nanomaterials setting up biosensor were carefully examined analytical techniques. Various modified electrodes constructed analyzed terms performance, morphology, size, shape nanomaterials. The GE-based aptasensor had a noteworthy conducive results against wide dynamic range 10.0-500.0 ng/mL, low limit detection (LOD) 0.667 ng/mL (significantly less than clinical cut-off), quantification (LOQ) 2.01 ng/mL. benefits provided such as broad range, sensitivity, selectivity, reproducibility, cost suggest tremendous potential non-invasive levels BC care diagnosis.

We used MoS2 nanosheets (MoS2 NSs) for surface modification of screen-printed electrode (MoS2NSs-SPE) aimed at detecting isoniazid (INZ) in the presence acetaminophen (AC). According to analysis, an impressive catalytic performance was found INZ and AC electro-oxidation, resulting appreciable peak resolution (~320 mV) both analytes. Chronoamperometry, differential pulse voltammetry (DPV), linear sweep voltammogram (LSV), cyclic (CV) were employed characterize electrochemical behaviors modified detection. Under optimal circumstances, there a relationship between current oxidation various levels (0.035–390.0 µM), with narrow limit detection (10.0 nM). The applicability as-developed sensor confirmed by determining tablets urine specimens, acceptable recoveries.

Electrochemical sensors provide an excellent platform for in situ water pollutant detection. Graphene-based electrochemical have been effective the analysis of different genres pollutants. However, complex, chemically intensive steps graphene fabrication and its modification pose challenges to large-scale application these sensors. Laser-induced (LIG) is a promising technology with simple, rapid, chemical-free, mask-free, scalable solution produce graphene-based Among diverse array pollutants, 4-nitrophenol (4-NP) critical owing acute toxicity adverse health effects on humans other living organisms. It known carcinogenic, mutagenic, teratogenic aquatic life, plants, human beings at very low concentrations. This work demonstrated simple nonreceptor-based sensor 4-NP detection by laser-induced printed polyimide (PI) films. The laser irradiation polymeric films results 3D porous structure formation, which increases electron transfer rate as well electrochemically active surface area. LIG was fabricated optimizing settings characterized SEM, TEM, XRD, Raman spectroscopy, XPS, TGA, EDS analysis. Using linear sweep voltammetry, behavior two concentration ranges from 0.15 1 μM 2.5 100 limit 95 nM. A higher sensitivity observed lower range, could be attributed increased sites LIG. showed good selectivity toward presence isomers phenolic compounds. Furthermore, it sewage samples spiked enhanced range pave way high-performance using environmental applications.

Background and purpose: Methotrexate (MTX) is a widely used anti-cancer drug, but its overuse can lead to significant side effects. Therefore, it very vital design simple sensitive analytical methods for determination. Experimental approach: In this work, an electrochemical sensor was prepared based on ionic liquid (IL)/Ni-Co layered double hydroxide nanosheets (Ni-Co-LDH)-modified carbon paste electrode IL/Ni-Co-LDH/CPE. Cyclic voltammetry, differential pulse chronoamperometry were applied evaluate the performance of designed MTX determination. Key results: The IL/Ni-Co-LDH/CPE exhibits linear relationship between peak current voltammetry concentrations in dynamic range 0.02 140.0 µM, with detection limit 0.006 µM. exhibited relative standard deviation values 1.7 3.7 % recovery tests real samples, indicating precision method. Conclusion: cost-effective good could be valuable therapeutic drug monitoring clinical diagnostics.
