Nonenzymatic Electrochemical Sensing of Glucose Using Hydrothermally Synthesized High-Specific-Surface-Area SnO₂ Nanoparticles.

ABSTRACT: The successful synthesis of high-surface-area SnO₂ nanoparticles with a spherical surface morphology and an average size of 16 nm was carried out using a hydrothermal chemical approach. The characterization of the as-prepared nanoparticles was carried out using XRD, TEM, FESEM, EDX, and UV-visible DRS techniques. The BET surface area of the SnO₂ nanoparticles was found to be 94.2 m²/g. Electrochemical analysis using cyclic voltammetry, chronoamperometry, and linear sweep voltammetry demonstrated the sensitivity of the nanoparticles toward glucose detection, showing a linear response from 0.25 to 3.0 mM and a low detection limit of 0.11 mM. The chronoamperometric analysis showed a rapid response of an electrode with the successive addition of different gluco
