Special Issue Information

Dear Colleagues,

Electrochemical sensors made using nanomaterials are recently emerging as the most popular type of sensors. These sensors have attracted a great deal of attention in chemical, pharmaceutical and biological studies due to their high sensitivity, simplicity and reliability. By using nanomaterials, it has become possible to develop and manufacture membrane-based sensors on a very small scale, allowing measurements to be made using a contact method in a very small amount of solution. As a rule, such sensors can be easily miniaturized, are flexible and have various shapes. Nanomaterial-based sensors are essential to current advances in analytical sciences, which are leading to the production of complete maintenance-free, durable and reliable ion sensors. This Special Issue, entitled “Nanomaterials-Based Membrane Sensors”, aims to highlight state-of-the-art developments in the field of potentiometric and voltametric sensors, involving both the design and application of sensors in various analytical tasks (e.g., environmental control, food analysis, agriculture, pharmaceuticals and medical applications). I invite you to contribute a variety of research articles, including review articles, short communications, and full-size research papers, to this Special Issue. 

I look forward to and welcome your participation in this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Membranes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
For the first time, a new composite voltammetric sensor based on yttria-stabilized zirconia doped with neodymium-carbon black-Nafion glassy carbon electrode (YSZNd-CB-Nafion/GCE) for the determination of metoprolol (MET) has been developed. The instrumental parameters and supporting electrolyte were optimized. For 105 s accumulation time, [...] Read more.
For the first time, a new composite voltammetric sensor based on yttria-stabilized zirconia doped with neodymium-carbon black-Nafion glassy carbon electrode (YSZNd-CB-Nafion/GCE) for the determination of metoprolol (MET) has been developed. The instrumental parameters and supporting electrolyte were optimized. For 105 s accumulation time, linearity was achieved in the range of 0.01 to 0.2 µM. The limit of detection (for 105 s accumulation time) was equal to 2.9 nM (2 µg/L), and was the best result in comparison to other voltametric sensors. The reproducibility of the metoprolol signal presented as relative standard deviation (RSD) was equal to 1.9% (n = 7). Additionally, our electrode is characterized by high stability, is easy to use, and has a short preparation time. The proposed sensor was found useful for MET determination in plasma and urine, as well as for pharmaceutical samples, with a good recovery parameter (96–108%). Flow injection analysis (FIA) with amperometric detection was also performed for MET determination. The recovery was calculated and was in the range 101–103%, suggesting that the proposed material may be applied in flow injection analysis. Full article
