Electrochemical non-enzymatic glucose sensors.
The electrochemical determination of glucose concentration without using enzyme is one of the dreams that many researchers have been trying to make come true. As new materials have been reported and more knowledge on detailed mechanism of glucose oxidation has been unveiled, the non-enzymatic glucose sensor keeps coming closer to practical applications. Recent reports strongly imply that this p...
متن کاملFree-standing nickel oxide nanoflake arrays: synthesis and application for highly sensitive non-enzymatic glucose sensors.
We report a seed-mediated hydrothermal growth of free-standing nickel hydroxide [Ni(OH)(2)] and nickel oxide (NiO) nanoflake arrays and their implementation as electrodes for non-enzymatic glucose sensors. Ni(OH)(2) nanoflakes were converted into porous NiO nanoflakes upon thermal annealing in air at temperatures of 300 °C or above. NiO nanoflake-arrayed sensors achieve an excellent glucose sen...
متن کاملGlucose-Sensitive Holographic (Bio)Sensors: Fundamentals and Applications
Nowadays sensors and especially biosensors play an important role in medical diagnosis and detection of food and environment contaminations. Biosensors’ facilities have been improved significantly by using technologies such as surface plasmon resonance, microfluidics, laser, and electrochemistry. These technologies are now available on chips in micro- and nano-scale and are capable of mea...
متن کاملCombinatorial discovery of alloy electrocatalysts for amperometric glucose sensors.
Combinatorial methods were used to search for active alloy electrocatalysts for use in enzyme-free amperometric glucose sensors. Electrode arrays (715-member) containing combinations of Pt, Pb, Au, Pd, and Rh were prepared and screened by converting anodic current to visible fluorescence. The most active compositions contained both Pt and Pb. Bulk quantities of catalysts with compositions corre...
متن کاملDisposable Non-Enzymatic Glucose Sensors Using Screen-Printed Nickel/Carbon Composites on Indium Tin Oxide Electrodes
Disposable screen-printed nickel/carbon composites on indium tin oxide (ITO) electrodes (DSPNCE) were developed for the detection of glucose without enzymes. The DSPNCE were prepared by screen-printing the ITO substrate with a 50 wt% nickel/carbon composite, followed by curing at 400 °C for 30 min. The redox couple of Ni(OH)₂/NiOOH was deposited on the surface of the electrodes via cyclic volta...
