Aluminum oxide quantum dots (Al2O3): An immediate sensing aptitude for the detection of urea

Green structure orienting and reducing agents of wheat peel extract induced abundant surface oxygen vacancies and transformed the nanoflake morphology of NiO into a plate-like shape with enhanced non-enzymatic urea sensing application

“…A comparison was made between the performance of the non-enzymatic urea sensor developed as of this writing and the results of several recently reported urea sensing studies, as shown in Table 3. [59][60][61][62][63][64][65][66][67][68][69][70][71][72][73] The presented urea sensor demonstrated a wide linear range, a low limit of detection, and a green mediated scaling up methodology, as shown in Table 3. The presented results were compared with both enzymatic and nonenzymatic urea sensors.…”

Rational construction of micro-plate-like iron oxide/aluminium oxide-fabricated screen-printed carbon electrode for the electrochemical detection of the antiandrogen drug

“…The usage of SPCE in comparison with the widely available electrodes such as platinum, gold, and carbon electrodes is due to its high thermal capacity, resistance to chemical attack, decreased electrical resistivity, and lower rates of oxidation with environmental gases or water vapors than other electrodes, as reported in the literature. 17 Metal oxides are a good choice as electrode materials for the electrochemical sensing of NTM given that they improve the analyte pre-concentration on the electrode surface, accompanied by a higher surface area. These advantages enable enhanced sensitivity and boosted electrochemical results.…”

Exploiting of Green Synthesized Metal Oxide Nanoparticles in the Potentiometric Determination of Metformin Hydrochloride in Pharmaceutical Products

“…Due to their strong electrocatalytic activity, low cost, high ability to bind organics, small size, high degree of crystallinity, and large surface-to-volume ratio, metal oxide nanoparticles are widely used and have been established as an active electrocatalyst for the detection of a variety of compounds [33]. Te active sites, electrochemically active surface area, surface energy, and other factors are generally closely related to the electrocatalytic properties of metal oxide nanoparticles [34]. Te catalytic materials were fabricated as small as possible to increase the number of available active sites and the available surface area so that the metal oxide-based nanoparticles exhibit high sensing performance [35][36][37][38].…”
