This paper describes the effect of the modification with two different cationic surfactants on the electrochemical behavior of ferrocene carboxylic acid (FCA), common redox-probe in bioanalysis. Cetyltrimethylammonium bromide (CTAB), a single-chain surfactant, and didecyldimethylammonium bromide (DDAB), double-chained, were evaluated. The purpose w...

In this paper, we report the synthesis of different types of water soluble poly(glycidyl methacrylate) (PGMA) derivatives containing alcohol, sulfonate, piperidyl, and dibencyl pendant groups. Their structures were characterized by infrared (IR), 1H NMR, 13C NMR, thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). It was...

Miniaturization is undoubtedly one of the main trends in Analytical Chemistry, due to the relevant advantages of small-size devices. Microchip electrophoresis (ME) devices have been one of the first and clearer examples of this trend. Nowadays, a relevant research area has grown around and is increasing very fast. However, the number of application...

Miniaturization is a well-established trend in the development of analytical devices, due to the important advantages it offers. Detection for this type of devices has to be in accordance and therefore easy integration and the employment of simple instrumentation are common requirements. These are fulfilled very well by the electrochemical detectio...
