Special Issue Information

Dear Colleagues,

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.
