Special Issue Information

In recent years, nanotechnology has led to the development of flexible and economic materials that operate for different potential applications in various fields of science and technology. The dimension size of nanomaterials is in the range of 1–100 nm. At present, electrochemical sensors are espoused for multifunctional pursuits due to their versatility, in which an electrode is exploited in their setup which acts as a transduction element. The informative material connected with electrochemical reactions (the response among cathode and anode) into material subjective and quantitative signs can be changed by the electrochemical sensor. An electrochemical cell device is a detector that analyzes the elements or pollutants in a highly-selective, sensitive, and reversible manner. The electrochemical sensor changes the number of chemicals into electrical signals. It is an analytical device for analyte detections. These sensors are promising aspirants in the clinical, environmental, as well as pharmaceutical fields. In rivalry with other analytical tools, electrochemical sensors are at the top due to their prompt and straightforward method of analysis, as well as due to the fact that they are inexpensive. The impact of electrochemical sensors in the industry is elevated just because of their continuous synthesis as well as environmental safety.

Scientists of various backgrounds (energy science, material science, biological engineering, chemistry, biochemistry, chemical engineering) are encouraged to contribute with cutting-edge research in this Special Issue of Micromachines, dedicated to the development of nanomaterials-based electrochemical sensors.

In this article, we describe an enzyme-based, membraneless, microfluidic biofuel cell for the continuous determination of glucose using electrochemical power generation as a transducing signal. Enzymes were immobilized on multi-walled carbon nanotube (MWCNT) electrodes placed parallel to the co-laminar flow in a Y-shaped microchannel. The microchannel was produced with polydimethylsiloxane (PDMS) using soft lithography, while the MWCNT electrodes were replicated via a PDMS stencil on indium tin oxide (ITO) glass. Moreover, the electrodes were modified with glucose oxidase and laccase by direct covalent bonding. The device was studied at different MWCNT deposition amounts and electrolyte flow rates to achieve optimum settings. The experimental results demonstrated that glucose could be determined linearly up to a concentration of 4 mM at a sensitivity of 31 mV∙mM−1cm−2. Full article
