Special Issue Information

Dear Colleagues,

The development of analytical methods capable of reliable, sensitive, selective, specific, robust, and accurate analysis of emerging contaminants in varying sample matrixes at low concentrations continues to be a significant analytical challenge. Areas of active research in the development of these sensors are based on the use of nanotechnology, material science, dyes, deep eutectic solvents, ionic liquids, electroanalytical techniques, and spectroscopic (atomic and molecular) methods. The overreaching goal of this Special Issue is to disseminate information concerning recent innovations and advances in the development and application of a variety of sensors for sample analysis. Topics of interest include but are not limited to the development of sensors for the analysis of consumable products, environmental and forensic samples, biomedical and pharmaceutical products, natural products, and bioanalytical and biomedical samples. Original research papers on innovations and advances in sensor development as well as review papers are welcome. We are extremely excited for and we look forward to your contribution to 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. 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.

Novel dipodal derivatives of an 18-membered diaza-crown ether with two diamide chains featuring methylmalonic or butylmalonic acid residues were obtained and tested as ionophores in ion-selective plasticized membrane electrodes. The objective of the study was to identify measurement conditions which ensure the most favorable performance for magnesium ion-selective electrodes. The relationship between the molar lipophilic anion salt-to-ionophore ratio and selectivity of electrodes was examined. The best result was obtained for the conventional electrode containing Mg2 ionophore. Calculated selectivity coefficients were as follows: logKMg/Ca = −2.77, logKMg/Na = −3.46 and logKMg.K = −2.24 (SSM, 1M). Full article
