“…In recent years, electrochemiluminescence (ECL) sensors have gained significant attention for detecting oxalate ions [ 20 ]. ECL technology combines principles of electrochemistry and luminescence, where the core principle involves the generation of chemiluminescent substances on the electrode surface through electrochemical reactions, enabling the detection of target analytes [ 21 ].…”

Convenient and highly sensitive detection of oxalate ions in body fluids is of crucial significance for disease prevention, diagnosis, and monitoring of treatment effectiveness. Establishing a simple solid-state electrochemiluminescence (ECL) sensing system for highly sensitive detection of oxalate ions is highly desirable. In this work, a solid ECL sensor was fabricated by immobilizing the commonly used emitter ruthenium(II)tris(bipyridine) (Ru(bpy)32+) on a double-layered bipolar silica nanochannel array film (bp-SNA)-modified electrode, enabling sensitive detection of oxalate ions in serum or urine samples. Cost-effective and readily available indium tin oxide (ITO) was used as the supporting electrode. Convenient fabrication of multiple negatively charged SNA (n-SNA)-modified ITO electrodes was achieved through the one-step Stöber solution growth method. Subsequently, a positive outer layer film (p-SNA) was rapidly prepared using an electrochemical-assisted self-assembly method. The double-layered bipolar silica nanochannel array film achieved stable immobilization of Ru(bpy)32+ on the electrode surface, facilitated by the electrostatic adsorption of Ru(bpy)32+ by n-SNA and the electrostatic repulsion by p-SNA. Utilizing oxalate ions as a co-reactant for Ru(bpy)32+, combined with the electrostatic enrichment of oxalate ions by p-SNA, the constructed sensor enabled highly sensitive detection of oxalate ions ranging from 1 nM to 25 μM and from 25 μM to 1 mM, with a detection limit (LOD) of 0.8 nM. The fabricated ECL sensor exhibited high selectivity and good stability, making it suitable for ECL detection of oxalate ions in serum and urine samples.

“…Oxalate (C 2 O 4 2– ) is a product of protein metabolism excreted by the kidneys and removed from humans via urine, therefore, the presence of oxalate within urine can be an indicator of kidney lesions such as renal failure and pancreatic insufficiency, among others. , Additionally, an increased urinary oxalate concentration can lead to the development and formation of calcium oxalate kidney stones; the urinary oxalate concentration should not exceed 460 μM over a 24 h period . The detection of oxalate has successfully been reported using a wide range of classic benchtop methodologies, such as fluorescence, luminescence, liquid chromatography–mass spectrometry, and microchip electrophoresis . These methodologies typically require sample collection followed by transport to a laboratory, where the sample is analyzed using these benchmark tests by a skilled user.…”

Mixing of graphite and carbon black (CB) alongside recycled poly(lactic acid) and castor oil to create an electrically conductive additive manufacturing filament without the use of solvents is reported herein. The additively manufactured electrodes (AMEs) were electrochemically benchmarked against a commercial conductive filament and a bespoke filament utilizing only CB. The graphite/CB produced a heterogeneous rate constant, k 0, of 1.26 (±0.23) × 10–3 cm s–1 and resistance of only 155 ± 15 Ω, compared to 0.30 (±0.03) × 10–3 cm s–1 and 768 ± 96 Ω for the commercial AME. Including graphite within the filament reduced the cost of printing each AME from £0.09, with the CB-only filament, to £0.05. The additive manufacturing filament was successfully used to create an electroanalytical sensing platform for the detection of oxalate within a linear range of 10–500 μM, achieving a sensitivity of 0.0196 μA/μM, LOD of 5.7 μM and LOQ of 18.8 μM was obtained. Additionally, the cell was tested toward the detection of oxalate within a spiked synthetic urine sample, obtaining recoveries of 104%. This work highlights how, using mixed material composites, excellent electrochemical performance can be obtained at a reduced material cost, while also greatly improving the sustainability of the system.
