“…Most of the optimization of SWV also deals with the traditional one-factor-at-a-time (OFAT) approach, examining SWV parameters such as frequency, step potential and pulse height [31][32][33]. If the factors are independent (which is rarely the situation), the most common practice is OFAT while holding all others parameters constant.…”

“…In particular, the combination of copper nanoparticles and single-wall nanotubes (solubilized in Nafion) allowed TNT measurements down to the 1 ppb level. The accumulation of RDX onto a mercury-coated glassy-carbon electrode was used for its sensitive measurement down to the 120 ppb level in connection to a 2 min deposition [18].…”

This article reviews recent advances in electrochemical sensing and detection of explosive substances. Escalating threats of terrorist activities and growing environmental concerns have generated major demands for innovative fielddeployable tools for detecting explosives in a fast, sensitive, reliable and simple manner. Field detection of explosive substances requires that a powerful analytical performance be coupled to miniaturized low-cost instrumentation. Electrochemical devices offer attractive opportunities for addressing the growing explosive sensing needs. The advantages of electrochemical systems include high sensitivity and selectivity, speed, a wide linear range, compatibility with modern microfabrication techniques, minimal space and power requirements, and low-cost instrumentation. The inherent electroactivity of nitroaromatic, nitramine and nitroester compounds makes them ideal candidates for electrochemical detection. Recent activity in various laboratories has led to the development of disposable sensor strips, novel electrode materials, submersible remote sensors, and electrochemical detectors for microchip (Lab-onChip) devices for on-site electrochemical detection of explosive substances. The attractive behavior of these electrochemical monitoring systems makes them very promising for addressing major security and environmental problems.

“…Recently, simple and sensitive analytical detection methods are needed in diagnostic systems. Voltammetric solutions have been found to have simple, compact (Ly et al 2002;Wang et al 2000), and micro working electrode systems (Lin et al 2005;Chen et al 2003) that can be used in in vivo diagnosis. Moreover, various voltammetric methods are often used in laboratory conditions.…”

In this article, we examined the performance of the voltammetric assay of caffeine using DNA immobilized onto a carbon nanotube paste electrode (DPE) and compared it with that of an ordinary carbon nanotube paste electrode (PE). Under optimal conditions, the working ranges for caffeine were from 0.1 to 12 mg l(-1) (for DPE) and 30-230 mg l(-1) (for PE). Detection limits (DLs) of 0.068 mg l(-1) (3.50 x 10(-7) M) DPE and 9.94 mg l(-1) (5.12 x 10(-5) M) PE were obtained and the relative standard deviation at the caffeine concentration of 5.0 mg l(-1) was 0.064% (n = 15) DPE under optimum conditions. The sensor could be implanted in a leaf skin or animal brain cell, which can then be interfaced with an electrochemical workstation. It can be used in real-time in vivo caffeine analysis in a live cell or leaf skin.
