Early Detection and Monitoring of Nephrolithiasis: The Potential of Electrochemical Sensors

Sensors, Journal Year: 2025, Volume and Issue: 25(8), P. 2547 - 2547

Published: April 17, 2025

Nephrolithiasis (kidney stone disease) continues to pose a significant global health challenge, affecting millions of individuals and placing substantial economic pressures on healthcare systems. Traditional diagnostic methods—such as computed tomography (CT), ultrasound, basic urinalysis—are often limited by issues including radiation exposure, lower sensitivity in detecting small stones, operator dependency, the inability provide real-time analysis. In response, electrochemical sensors have emerged innovative powerful tools capable rapid, sensitive, specific detection key biomarkers associated with nephrolithiasis. This review highlights advances approaches for monitoring oxalate uric acid, two primary metabolites implicated kidney formation. We discuss principles electrode design fabrication, nanomaterial integration, 3D printing, molecular imprinting, which markedly improved limits selectivity. Furthermore, we critically evaluate practical challenges—such sensor fouling, reproducibility, stability complex biological matrices—that currently impede widespread clinical implementation. The potentials miniaturization point-of-care integration are emphasized, an eye toward continuous or home-based systems that can offer personalized insights into risk formation progression. By consolidating recent findings exploring future trends multi-analyte wearable diagnostics, this provides roadmap translating from research laboratories routine practice, ultimately aiming enhance early intervention improve patient outcomes

Study curing of epoxy resin by Isophoronediamine/ Triethylenetetramine and reinforced with montmorillonite and effect on compressive strength

BMC Chemistry, Journal Year: 2024, Volume and Issue: 18(1)

Published: Oct. 28, 2024

Abstract Epoxy is a widely used thermosetting resin recognized for its exceptional performance in adhesives, coatings, and various other applications, attributed to high tensile strength, stiffness, electrical performance, chemical resistance. Epoxy-clay nanocomposites are extensively employed across diverse industries. The physical properties of these influenced by the processing methods, clay modifiers, curing agents during their preparation. In this study, epoxy/nanoclay composites based on Diglycidyl Ether Bisphenol-A (DGEBA) will be cross-linked using Isophorone Diamine (IPD), cycloaliphatic amine, Triethylenetetramine (TETA), linear aliphatic amine. initial phase research assess impact different types cross-linkers, both individually combination at molar ratios (such as Diamine: (IPA: TETA) / 25:75 75:25), compressive strength epoxy mortar. subsequent phase, formulation with an (IPD: TETA which demonstrates highest selected further investigation. This evaluate effects weight percentages (3%, 5%, 7%) organically modified montmorillonite (OMMT). prepared characterized range techniques, including Fourier Transform Infrared Spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), Scanning (SEM). composite IPD: 75:25 3 wt % OMMT expected show 94 MPa.
