Perspective—Thick Film Technology

Abstract

Thick film technology (TFT) offers a new platform for analytical procedures in electrochemistry. The most routine technology is screen printing. However, it can introduce new procedures connected with miniaturization or combination of microfluidic and electrodes. Here, TFT use in electrochemistry is discussed and examples of different sensors are demonstrated. Details are referred to in the original literature. Advanced applications combining TFT with other technologies are demonstrated (capillary electrophoresis on a chip and a sensor with integrated heating and thermometer). The future of TFT in electrochemistry is discussed, also the drawbacks, connection to production and commercial application are noticed.

Review—An Overview on Recent Progress in Screen-Printed Electroanalytical (Bio)Sensors

“…23 There are several factors that go into designing an effective SPE sensor, including the ink composition, curing temperature, pre-treatment methods and surface roughness, which all contribute to defining the sensor's sensitivity and selectivity, as recently reported for thick-film technology. 24 Ink or pastes.-The use of a print medium, such as ink or paste, to make a sensor within the screen-printing procedure is crucial to transferring the printed design (Fig. 3b).…”
