Facile synthesis of perovskite-type NdNiO₃ nanoparticles for an effective electrochemical non-enzymatic glucose biosensor

Abstract

The detailed facile synthesis and material characterizations of NdNiO3 nanoparticles for a non-enzymatic glucose sensor application were discussed briefly in this paper.

Deposition of nanomaterials: A crucial step in biosensor fabrication

“…Sivakumar et al synthesized perovskite-type NdNiO3 nanoparticles (NPs) and suspended them in ethanol, followed by drop casting onto the glassy carbon electrode (GCE) surface to fabricate an electrochemical-based nonenzymatic glucose biosensor [84]. They attributed the electrocatalytic performance of their fabricated biosensor to the synergetic effect of the nanomaterials that resulted in fast electron transfer.…”

Electrospun porous La–Sr–Co–Ni–O nanofibers for highly sensitive non-enzymatic glucose detection

“…Perovskite oxide non-enzymatic glucose biosensors have shown great advantages, such as high sensitivity, high surface area, porosity, low cost, and flexibility. In particular, non-enzymatic glucose biosensors are stable to environmental change as no enzymes are used 22,26,[32][33][34][35][36][37][38][39][40] . Herein, lanthanum, strontium, nickel and cobalt perovskite nanofibers, a composition that has not been reported previously, were synthesized by using electrospinning method and characterized by various techniques, such as X-ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM).…”

Low oxygen pressure synthesis of NdNiO3-δ nanowires by electrospinning

“…compounds are a candidate for these electronic correlated systems since these compounds present a rich phase diagram and are one of the few oxides that allowed a direct correlation between the structure and the physical properties [2,3]. These compounds can be suitable for use in glucose sensors [4], synaptic transistor devices [5], resistive random access memory devices [6,7], photovoltaic devices [8,9], etc.…”

“…In fact, the synthesis of these compounds requires high oxygen pressure and high temperature. Many methods have been used to obtain these compounds, including sol-gel method, hydrothermal synthesis [4], and solidstate reaction synthesis [15]. Among these compounds, NdNiO 3 has been widely investigated as it can be obtained in less severe temperature conditions and oxygen pressure [11,16,17].…”
