Special Issue Information

Dear Colleagues,

We are pleased to announce that the Chemical Sensors Section is now compiling a collection of papers submitted by the Editorial Board Members (EBMs) of our section and by outstanding scholars in this research field. We welcome contributions as well as recommendations from EBMs. The scope of this Special Issue includes, but is not limited to, the following topics: new developments and recent improvements in the design, synthesis, and performance evaluation of materials for sensitive layers and transducers; the study of their sensing mechanisms; the evaluation, processing approaches, and applications of chemical sensors; the driving electronics, data processing, and chemical sensor array chemometrics; DNA chips; lab-on-a-chip technology; microfluidic devices; nanobiosensors and nanotechnology used in biosensors.

In this Special Issue, we aim to publish high-quality manuscripts, particularly review contributions, that demonstrate the advances in chemical sensors and biosensors.

Prof. Dr. Eduard Llobet
Guest Editor

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. Sensors is an international peer-reviewed open access semimonthly 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 2600 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
A voltammetric method based on the use of screen-printed carbon electrodes (SPCEs) is presented for the simultaneous determination of salbutamol (SAL), sulfamethoxazole (SMX), and trimethoprim (TMP), with high sensitivity, fast response, and excellent repeatability and reproducibility. Under the optimal voltammetric conditions, the simultaneous [...] Read more.
A voltammetric method based on the use of screen-printed carbon electrodes (SPCEs) is presented for the simultaneous determination of salbutamol (SAL), sulfamethoxazole (SMX), and trimethoprim (TMP), with high sensitivity, fast response, and excellent repeatability and reproducibility. Under the optimal voltammetric conditions, the simultaneous analysis showed linear ranges of 0.3–2.5 mg L−1, 0.3–11.1 mg L−1, and 0.5–9.0 mg L−1 for SAL, SMX, and TMP, respectively, and detection limits of 83.8 μg L−1, 88.7 μg L−1, and 139.2 μg L−1, respectively. Additionally, the developed method was successfully validated by the analysis of a spiked river water sample with satisfactory recovery values in the range of 97.0–98.8%. The added value of the presented method relays in combining cost-effective disposable SPCEs with rapid analysis (<30 s), providing portable electrochemical tools for the on-site monitoring of pharmaceutical residues, which is critical for addressing contamination linked to anthropogenic activity.
