Sensors based on potentiometric and spectrometric measurements of electrical and optical signals, respectively, have been utilized for detection of interesting analytes for the past 4–5 decades. Both types of sensors rely upon binding of an interesting analyte by a ligand (molecular or ionic) in a reversible or irreversible manner, accompanied by a measureable signal that is usually proportional to analyte concentration. A highly desirable characteristic of chelating ligands used in these sensors is selectivity for specific analytes, toward analyte detection and quantitation with minimal or no interferences. Currently, there are a plethora of analytical applications of potentiometric and optical sensors containing selective chelators, from food analysis, to industrial quality control, to biological, medical, and environmental analyses. The need for sensors incorporating selective chelators for detection and quantitation of analytes in a wide range of applications will continue for years to come.
This special issue of Sensors seeks to address the role of selective chelators in the design and implementation of potentiometric and optical sensors for chemical analysis, and the issues related to their use in sensors. Thus, we solicit review articles and original research papers on chelators for inorganic and organic anions and cations as well as neutral molecules, selectivity of chelators for specific cations, anions, and neutral molecules, utilization of photochromic and electrochromic molecules containing chelating functional groups toward photo- or electroreversible analyte sensing, and applications of selective chelating agents to the determination of a wide range of analytes. New analyte-specific chelators with high selectivity, new approaches to selective analyte chelation coupled with schemes for reversibility, and novel applications of selective chelators in sensors for detection and quantitation of analytes, are also considered.

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 monthly journal published by MDPI.
