This chapter investigates the fabrication of metallic nanowire arrays and their application as sensors or biosensors to determine glucose, glutamate and H 2 O 2 . Nanowire-based material provides a very high electrochemically active surface area, thereby leading to very high detection sensitivity. To date, noble metals, such as platinum (Pt), gold (Au), silver (Ag) and their alloys, have been extensively investigated as anodic materials in the design of non-enzymatic sensor surfaces. Vertically aligned structures such as free-standing nanowire arrays are particularly useful for sensing and biosensing applications due to their high sensitivity to surface interactions. Although nanowires have been fabricated by various methods, a simple fabrication technique which incurs reasonable costs for practical applications is highly desired. In this chapter, a template-based fabrication of nanowire arrays of Au, Pt and nickel (Ni) will be described. These materials have been characterized using X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The catalytic activity and the suitability of these materials as electrochemical sensors have been investigated by cyclic voltammetry and amperometry.

“…[13][14][15][16] Among these candidates, NiO has recently received tremendous interest in supercapacitor and biosensor applications because of its low cost, low toxicity, and high electrocatalytic performance. [ 17,18 ] However, the high peak potential and low conductivity limit its practical biosensing applicability. This limitation can be overcome by developing a hybrid structure with excellent electrical conductivity and unique chemical and physical properties of carbon materials, including carbon nanotubes and graphene.…”

Selective and sensitive glucose sensors with fast response for screening diabetic blood level are demanded. In this paper, the one-pot nanoarchitecture of dendritic NiO@carbon-nitrogen (C-N) dots (designated as NCD) sphere-wrapping Ni foam electrodes are reported as an effective and sensitive glucose sensor in blood samples. In this construction design, the NCD sphere electrode with excessive surface defects, large fractions of catalytic active sites, high surface area, and mobility of electron transfer through the actively surface NCD sphere can massively enhance the electrocatalytic activity for nonenzymatic glucose detection in diabetic blood. This portable sensor enables highly sensitive recognition of glucose detection (≈0.01 × 10 m) over a wider linear range (≈0.005-12 × 10 m) with rapid response time of a few seconds. The key result is that the engineered NCD sphere electrodes function as simple, easy-to-use electrochemical sensing assays of glucose levels in diabetic blood patients with a wide range of precision or linearity, recyclability, and excellent selectivity, even in the presence of potentially interfering organic (ascorbic acid, uric acid, dopamine, lactose, maltose, and sucrose) and inorganic (NaCl, Na SO , KCl, and K SO ) species. The results demonstrate the potential for the electrochemical sensors to be used in preventing serious health problems associated with diabetes mismanagement.

Sputtered Ag on zinc oxide (ZnO) nanorod-structures grown on a carbon paper substrate were investigated as an electrocatalyst for non-enzymatic oxidation of urea. The Ag/ZnO nanorod-modified electrodes were characterized by cyclic voltammetry and chronoamperometry in 1 M KOH electrolyte with 0.33 M urea. The synergetic electrochemical performance due to the combined Ag and ZnO nanorod materials shows a good sensitivity of 0.1622 μAμM −1 cm −2 with a low detection limit of 13.98 μM. Simple and scalable fabrication of the electrode can make it a potential candidate for non-enzymatic urea sensor with reproducible and sensitive detection. Urea [(NH 2 ) 2 CO] is currently used as a fertilizer and a starting material for plastic production and drugs. The urea concentration is considered as an important indicator in process of agriculture chemistry, food and pharmaceutical products, and environmental protection.1 Urea is also an end product of the metabolic breakdown of proteins in all mammals and some fishes.2 Therefore, the measurement of urea can be important in biomedical and clinic analysis. It is reported that abnormal levels of urea in serum can be related to several diseases such as renal, dehydrant, and hepatic issues.3 Recently, urea is also explored as potential hydrogen storage materials, and monitoring of urea concentration may be important in developing highly performing energy storage and conversion systems. 2Many sensing platforms are based on the use of enzyme to hydrolyze urea for the release of NH 4+ , HCO 3− , and OH − ions. This method can suffer the difficulties associated with enzyme immobilization technique and stability problems caused by denaturation of enzyme.3 Therefore, electrochemical approach regarding the oxidation of several metals and/or metal oxides such as Ni/NiO 2 has been investigated for non-enzymatic detection of urea. Ni based catalyst is reported to present better performance in the electro-catalytic oxidation of molecules such as urea 1 and glucose.3 However, problems related to degradation and expansion of the Ni based catalyst structure during the oxidation still exist. 4 Moreover, nickel's reaction with dissolved oxygen in aerated alkaline solution may result in potential variation driven by formation of Ni(OH) 2 and NiOOH. Such change in concentration of OH − anions is a dominant factor of Ni based catalyst to examine physiological measurement. 4In this letter, new set of silver catalysts on ZnO nanorods/carbon electrode was investigated as a method of non-enzymatic urea detection. Morphological and electrochemical properties of Ag catalyst deposited ZnO nanorods were characterized to understand the relation on morphologies of the electrodes and electrochemical response in urea detection. Non-enzymatic detection from the electrode demonstrates good sensitivity on the determination of urea concentration. ExperimentalCarbon paper (Fuel cells etc.) was cut into a 0.3 cm 2 piece and attached on a flat glass substrate. The carbon paper on the glass substrate was then dipped int...
