The screen-printed electrode (SPE) sensor is widelyemployedin food analysis, environmental health monitoring, disease detection, toxin detectionandother applications.As it crucial for the SPE to have an outstanding performance, this study examined effects of manipulatingthe working electrode(WE)radius, gap spacing between electrodes, and counter (CE) width on performance sensor.Finite element s...

This short article overviews the use of screen-printed electrodes (SPEs) in field electroanalysis and compares their application against traditional laboratory based analytical techniques. Electroanalysis coupled with SPEs can offer low-cost, precise, sensitive, rapid, quantitative information equivalent results. The combined reduces need sample transportation preparation to a centralised allow...

A simple, fast, sensitive and low-cost voltammetric method using a screen-printed carbon electrode (SPCE) is presented in this work for the simultaneous determination of ascorbic acid (AA), paracetamol (PA), dextromethorphan (DX) caffeine (CF) both pharmaceutical formulations samples environmental interest. The oxidative peak current displayed linear dependence on concentration within range 1.7...

Graphite electrodes fabricated by screen-printing have been used as amperometric detectors in biosensors based on NAD(+)-dependent dehydrogenases, tyrosinase, or genetically modified acetylcholinesterases. The mono-enzyme sensors have been optimized as disposable or reusable devices for detection of a variety of substrates important in the food industry ( D-lactic acid, L-lactic acid, acetaldeh...

The promising advantages of Prussian Blue (PB) as catalyst and of the thick film screen printing technology have been combined to assemble sensors with improved characteristics for the amperometric determination of H(2)O(2). PB-modified screen printed electrodes were applied to detect H(2)O(2) at an applied potential of -0.05 V versus the internal screen printed Ag pseudoreference electrode, sh...
