“…(Note: to be comparable to [23 -25], sensitivity of the porous copper system was presented in mA cm À2 mM À1 by dividing the sensitivity of 220 AE 6 mA mM À1 and 60 AE 2 mA mM À1 with the real surface area of porous copper electrode, 0.91 AE 0.09 cm 2 , that was determined from the voltammetric curve, followed the method described in [26]). Although the limit of detection in this work is higher than some nonenzymatic work such as nickel powder dispersed sol -gel derived ceramic graphite composite [27] and porous platinum [24], both of which provided LOD of 0.1 mM. However, the upper linear limit of the present work (10 mM) was either higher ([27] ¼ 0.5 -5000 mM) or comparable ([24] ¼ 0.001 -10 mM) making it suitable for the analysis of system that has a high glucose concentration range.…”

A nanoporous copper film was fabricated on a copper wire by electrodeposition of copper/zinc alloy and chemically etching of zinc. The surface morphology was investigated by SEM. When applied to detect glucose in an amperometric flow injection system the porous copper electrode provided 12 times higher sensitivity than solid copper. It could be continuously used up to 50 times (%RSD ¼ 5.7). Different preparations of the porous film provided reproducible responses (P < 0.05). Detection of glucose in E. coli cultivation medium compared well with spectrophotometric technique (P < 0.05). This simple technique can produce a nanoporous electrode with good performances and can easily be applied to other metals and analytes.

“…Enzymatic glucose sensors, based on the immobilization of glucose oxidase (GOD) on various substrates, are the focus of most previous studies on this subject due to their high selectivity and sensitivity. However, these GODbased biosensors have some disadvantages, such as complicated immobilization procedures, chemical instability and high cost, which limit their practical application [16]. To address these limitations, an alternative approach based on the direct electrooxidation without the use of enzyme, "non-enzymatic" sensors have been tried.…”

“…Progress has been made in the amperometric measurements of glucose based on various metal nanomaterials without using enzymes [11][12][13][14][15][16][17][18][19][20][21][22]. However, their further applications are limited owing to the surface being poisoned and etched during the detection process.…”

Preparation of grain size controlled boron-doped diamond thin films and their applications in selective detection of glucose in basic solutions

et al. 2010

Boron-doped diamond (BDD) thin films with different crystal grain sizes were prepared by controlling the reacting gas pressure using hot filament chemical vapor deposition (HFCVD). The morphologies and structures of the prepared diamond thin films were characterized by scanning electron microscopy (SEM) and Raman spectroscopy. The electrochemical responses of K 4 Fe(CN) 6 on different BDD electrodes were investigated. The results suggested that electron transfer was faster at the boron-doped nanocrystalline diamond (BDND) thin film electrodes in comparison with that at other BDD thin film electrodes. The prepared BDD thin film electrodes without any modification were used to directly detect glucose in the basic solution. The results showed that the as-prepared BDD thin film electrodes exhibited good selectivity for detecting glucose in the presence of ascorbic acid (AA) and uric acid (UA). The higher sensitivity was observed on the BDND thin film grown on the boron-doped microcrystalline diamond (BDMD) thin film surface, and the linear response range, sensitivity and the low detection limit were 0.25-10 mM, 189.1 A mmol 1 cm 2 and 25 M (S/N=3) for glucose in the presence of AA and UA, respectively. diamond thin films, electrochemical properties, selective, glucose, detection
