Abstract

The increasing demand for fast and on-site information has generated great interest in developing simple and portable analytical devices that provide reliable responses. Electroanalytical devices fit perfectly with these purposes because of their ease of use, low cost and facility of miniaturization. Moreover, the growing interest in the construction of do-it-yourself electronic devices has spread the use of common and mass-produced materials for the development of analytical devices. In this context, it is presented here the use of gold-plated pins, from standard connections, and stainless-steel pins, from needlework, as electrodes in (bio)electroanalytical platforms. Three different analytical platforms combining those pins with paper, transparency sheets or micropipette tips were constructed and applied in food and environmental analyses: glucose determination in beverages and surfactant analysis in water.
Keywords: electrochemical sensor; electroanalytical device; paper-based analytical device; pin-based electrodes; micropipette-tip electrochemical cell; enzymatic sensor; glucose; water analysis; sodium dodecyl sulfate electrochemical sensor; electroanalytical device; paper-based analytical device; pin-based electrodes; micropipette-tip electrochemical cell; enzymatic sensor; glucose; water analysis; sodium dodecyl sulfate
