“…Hence, numerical efforts have been devoted to improve their performances. 1 Recently, the demand for miniaturized biosensors has been increasing, and had led to the development of portable or in vivo sensing systems. Along this line, many researchers have focused on applying microelectrodes to electrochemical biosensors.…”

This paper describes a diffusion-controlled electrolysis of glucose with mediated bioelectrocatalysis at microdisk-electrodes. Under conditions of an extremely fast enzyme reaction, compared with the diffusion of glucose, the current in potential-step chronoamperometry reaches an almost steady state within 10 s, and is proportional to the glucose concentration. The current can be detected at +0.1 V (vs. Ag|AgCl) with 9,10-phenanthrenequinone as a mediator. The addition of carboxymethylcellulose increased the linear range up to 10 mM.

“…Another trend in ISE research is to develop more robust and practical devices, thus there is significant interest on the development of all-solid state ISEs and miniaturized systems [93]. A very interesting discussion about advances in potentiometric sensors was written by Privett et al [94]. These authors present an impressive number of references discussing the main advances in potentiometry covering ISEs development and analytical applications in several areas.…”

“…Upon target binding, the electrochemical signal of redox reporter is changed, which is directly related to the concentration of target species. Electrochemical biosensors have been attracting much attention owing to their simple configurations, low cost, multiplexed detection capabilities, high sensitivity and selectivity, as well as ease of miniaturization for portable point-of-care diagnostics and environmental monitoring (Kimmel et al, 2012;Privett et al, 2010).…”
