Progress in the development of continuous glucose monitoring technologies are discussed, specifically focusing on subcutaneous implantable electrochemical glucose sensors. The first dedicated glucose analyzer for direct measurement of glucose in whole blood samples was launched by Yellow Spring Instruments in 1975. Second generation electrochemical glucose biosensors employ electron mediators, which are capable of shuttling electrons from the redox center of the enzyme to the surface of the electrode, thus allowing for a lower applied electrode potential. Glucose detection based on optical approaches are categorized as fluorophore and non-fluorophore. Fluorophore-based approaches employ a spectroscopic affinity sensor wherein glucose and a fluorophore-labeled molecule bind competitively with a receptor. The synthesis of antifouling materials has evolved to be a common strategy for improving glucose sensor functionality as the initial adhesion of proteins and cells onto a glucose sensor dampens sensor performance.

In the above-named article [ibid., vol. 60, no. 9, pp. 2791¿2798, Sep. 2012], a balanced-to-balanced power divider/combiner structure is proposed. The proposed structure employs four lumped resistors for the isolation and matching purposes. This communication shows that this circuit can be modified into a simplified structure involving only two resistors with similar performance. © 1963-2012 IEEE. Source

The q-Euler numbers and polynomials were recently constructed [T. Kim, "The Modified q-Euler Numbers and Polynomials," Adv. Stud. Contemp. Math., 16, 161-170 (2008)]. These q-Euler numbers and polynomials have interesting properties. In this paper, we prove a theorem of the von Staudt-Clausen type for q-Euler numbers; namely, we prove that the q-Euler numbers are p-adic integers. Finally, we prove Kummer-type congruences for the q-Euler numbers. © 2013 Pleiades Publishing, Ltd. Source

In this paper, we present new generating functions related to q-Euler numbers and polynomials of higher order. Using those generating functions, we present new identities involving q-Euler numbers and polynomials of higher order. © 2010 Pleiades Publishing, Ltd. Source

The important biological roles of nitric oxide (NO) have prompted the development of analytical techniques capable of sensitive and selective detection of NO. Electrochemical sensing, more than any other NO detection method, embodies the parameters necessary for quantifying NO in challenging physiological environments such as blood and the brain. In this tutorial review, we provide a broad overview of the field of electrochemical NO sensors, including design, fabrication, and analytical performance characteristics. Both electrochemical sensors and biological applications are detailed. © The Royal Society of Chemistry 2010. Source
