“…ZnO has a large excitonic energy, lowcost synthesis, biocompatibility, good electrochemical activities, non-toxicity, high-electron communication features and high mechanical strength [21]. The nZnO has been used previous for the fabrication of different sensors and biosensors [22][23][24][25][26].…”

“…2i), to provide a favorable microenvironment for LOD [49]. An electrochemiluminescence lactic acid biosensor based on the same structure was proposed, by combining analytical electrochemistry and luminescence spectroscopy [85]. A low detection limit (4 nM) was a result of the low background signal of the luminescence technique.…”

Biosensing has developed tremendously since it was demonstrated by Leland C. Clark Jr. in 1962. ZnO nanomaterials are attractive candidates for fabricating biosensors, because of their diverse range of nanostructures, high electron mobility, chemical stability, electrochemical activity, high isoelectric points which promote enzyme adsorption, biocompatibility, and piezoelectric properties. This review covers ZnO nanostructures applied in enzyme biosensors, in the light of electrochemical transduction and field effect transduction. Different assembly processes and immobilization methods have been used to load enzymes into various ZnO nanostructures, providing enzymes with favorable micro-environments and enhancing their sensing performance. We briefly describe recent trends in ZnO syntheses, and the analytical performance of the fabricated biosensors, summarize the advantages of using ZnO nanostructures in biosensors, and conclude with future challenges and prospects.

“…H 2 O 2 was produced by enzymatic reaction of GOD, and ECL could be obtained by the reaction between luminol and H 2 O 2 for sensing glucose [69]. A FI optical fiber glucose and lactate biosensor [70][71][72] and a thin-film glucose ECL biosensor were also developed based on alcohol-free mesoporous molecular sieve silica modified electrode [73] and immobilization of GOD with MWNT/ Nafion film [74][75][76].…”

The development of electrochemiluminescence (ECL) applications is a growing field, having the potential advantages of ECL over conventional chemiluminescence. ECL has found various applications in immunoassays, DNA probe assays, and aptasensors by employing ECL-active species as labels on biological molecules. The recent use of ECL to detect many chemically, biochemically, clinically, and environmentally important analytes is reviewed.
