Nanostructured Nickel‐based Non‐enzymatic Electrochemical Glucose Sensors

Abstract

Glucose detection is considered a significant area and has remained the topic of considerable attention. Remarkable technological advancements have been observed in diabetes monitoring in the past decades. This continual progress helps to track recent trends in development as well as identify challenging issues in glucose sensor construction. Thus, a comprehensive synopsis of the most recent advancements and developments in the study of nickel (Ni) nanostructure-based sensors for efficient trace-level glucose detection, following non-enzymatic and electrochemical methods, is provided in this review. Moreover, this review is intensively focused on the methodologies for the structure, morphology, preparation, and enforcement of a variety of Ni nanostructures, including Ni nanosheets with metals, Ni nanospheres with metals/mixed metals, Ni-metal nanocomposites, metal nanoparticles-decorated Ni nanowires, Ni nanoparticles, Ni-decorated metal nanotube arrays, Ni nanoneedles and nanorods with metals, nanoporous, nanoplates, nanocoated Ni with metal composites, and Ni-composed hybrid nanostructures. Various demonstrations and categorizations are provided on Ni-based nanostructures for a clear understanding for diverse readers.

Research Progress on Biomimetic Nanomaterials for Electrochemical Glucose Sensors

“…Layered double hydroxides (LDH) biomimetic materials also have been investigated and used in electrochemical glucose sensing because of their simple preparation, adjustable chemical composition, and excellent oxidation reducibility [ 41 , 133 ]. Bimetallic LDH, especially Ni-based bimetallic LDH, have attracted much attention in glucose sensing.…”

“…Recently, reviews have mainly focused on two major aspects for electrochemical glucose sensors: new electrochemical detection technologies based on different targets [ 25 , 37 , 38 ] and biomimetic nanomaterials [ 33 , 39 , 40 , 41 , 42 , 43 ]. For various targets, Su’s group overviewed the implantable and wearable electrochemical glucose sensors, which contain saliva, sweat, tears, and interstitial fluid sensors [ 37 ]; Peng et al discussed the mechanisms of electrochemical and optical sensors for glucose detection in body fluids, such as blood, saliva, sweat, interstitial fluid, tears, and urine [ 38 ].…”

However, there are few reviews about biomimetic nanomaterials focusing on improving electrochemical glucose sensing performance.…”

Enzyme-free electrochemical sensor platforms based on transition metal nanostructures for clinical diagnostics

“…Transition metal-based oxides/suldes/phosphides/ selenides nanostructures have wide-ranging services such as enzyme-mimic electrocatalysts for sensing lactic acid and glucose due to their less-price, enormous bio-compatibility, boosted electron-transfer process, and high adsorption aptitudes. 28,[46][47][48] These nanostructured materials have also been employed as electrode materials in numerous potential applications, including lithium-ion batteries, electrocatalysis, highperformance supercapacitors, and electrochemical sensors. [49][50][51][52][53] In particular, increased electrical conductivity, rich redox chemistry, various atomic congurations, and crystalline entities in binary nickel sulphides (NiS) have led to improved electrocatalytic abilities.…”

Advances in nanostructured material-based non-enzymatic electrochemical glucose sensors

“…[39][40][41][42] However, over the past few decades, few reviews have focused on this rapidly developing eld and the structure-performance correlation of non-enzymatic glucose sensors has not been systematically summarized. 43 Therefore, in this review, we start by discussing the general functional mechanism of a non-enzymatic glucose sensor in order to describe the key electrode material requirements. Then, the contribution of nanostructures to performance enhancement is introduced in the context of geometric congurations from zero to three dimensions.…”
