A cobalt oxide nanoparticle-modified glassy carbon (CONM/GC) electrode was prepared by potential cycling in a pH-controlled solution containing tartrate. The electrocatalytic oxidation of glucose on CONM/GC electrode in alkaline solution was investigated and the kinetics was developed. In cyclic voltammograms, the peak current of the oxidation of low valence cobalt oxide in the presence of glucose is increased and it was followed by a decrease in the corresponding cathodic current. This suggested that glucose oxidation was being catalysed on the redox mediator with an electrocatalytic mechanism. Using cyclic voltammetry, chronoamperometry, steady-state polarisation measurements and impedance spectroscopy, the kinetic parameters of the glucose electrooxidation such as charge-transfer coefficient, the catalytic reaction rate constant and the diffusion coefficient were determined. Based on the results, an efficient enzymeless sensing procedure for determination of glucose was developed. The resulting sensor exhibited excellent performance for the glucose determination and a sensitive and time-saving amperometric procedure was successfully applied for the quantification of glucose in both batch and flow systems. Glucose was determined with a linear range of 0.7-60 mM, a limit of detection of 0.15 mM and a sensitivity of 2515.35 mA mM À1 cm À2 in batch system and with a linear range of 1.3-50 mM, a limit of detection of 0.14 mM and a sensitivity of 3240.25 mA mM À1 cm À2 in the flow system.

“…However, it is also well-known that platinum surfaces are particularly sensitive to poisoning with chemisorbed intermediates (Bae et al, 1990;Bae et al, 1991). To solve this problem, different heavy atoms (Tl, Pb, Bi and W) have been used as adatoms to modify platinum surfaces to raise electrochemical activity of platinum (Park et al, 2006). Other studies relate glucose oxidation on platinum alloys in which the second metal can be Rh, Pd, Au, Pb (Sun et al, 2001), Bi, Ru and Sn (Becerik & Kadirgan, 2001).…”

“…Unlike the enzymatic glucose sensors, non-enzymatic sensors have several attractive advantages such as stability, simple fabrication, reproducibility, low cost, and free from oxygen limitation. 56 Many research groups have attempted to detect glucose on the basis of direct electrochemical oxidation of nanomaterials (e.g., Nano-porous Pt-nanoparticles, carbon nanotube, and Pt nanotube arrays). 57−64 Several research efforts have been performed to develop implantable non-enzymatic glucose sensors for continuous glucose monitoring.…”

Microneedles have emerged for transdermal monitoring of biomarkers, which are a miniaturized replica of hypodermic needles with length-scales of hundreds of micrometers, with a goal to achieve time-sensitive clinical information for routine point-of-care health monitoring. Transdermal biosensing via microneedles offers remarkable opportunities for moving biosensing technologies from research laboratories to real-field applications and enables development of easy-to-use point-of-care microdevices, minimally invasive, and with minimal-training features that are very attractive for both developed and emerging countries. This would eliminate the need for blood extraction using hypodermic needles and in turn, reduce the related problems such as infections in the patients, sample contaminations, and analysis artifacts. In this review, we provide a general overview of recent progress in microneedlebased sensing research, including: (a) in-vivo microneedle diagnostic systems for glucose monitoring with an emphasis on sensor construction and general health monitoring (b) in-vitro use of microneedle sensors. The main objective of the review is to provide a thorough and critical analysis of recent advances and developments in microneedle research field and to bridge the gap between microneedles and biosensors.
