Abstract
This review article highlights the importance of novel charge transfer (CT) sensing approach for the detection of ions which are crucial from environmental and biological point of view. The importance, principles of charge transfer, ion sensing, its different types, and its basic process will all be covered here. The strategy has been reported with enormous sensitivity and fast signaling response owing to the fact that strong electronic connection communication exists between donor (D) and acceptor (A) part. Important discoveries made since 2010 will be examined. Herein, we will showcase the binding constants, conditions employed for sensing, and limit of detection of crucial ions via CT based sensors that researchers have bough forth for real-time applications. Additionally, the focus will be on the mechanistic aspects and signaling response as a result of the interaction between ion and sensor molecule.
期刊介绍：
Critical Reviews in Analytical Chemistry continues to be a dependable resource for both the expert and the student by providing in-depth, scholarly, insightful reviews of important topics within the discipline of analytical chemistry and related measurement sciences. The journal exclusively publishes review articles that illuminate the underlying science, that evaluate the field''s status by putting recent developments into proper perspective and context, and that speculate on possible future developments. A limited number of articles are of a "tutorial" format written by experts for scientists seeking introduction or clarification in a new area.
This journal serves as a forum for linking various underlying components in broad and interdisciplinary means, while maintaining balance between applied and fundamental research. Topics we are interested in receiving reviews on are the following:
· chemical analysis;
· instrumentation;
· chemometrics;
· analytical biochemistry;
· medicinal analysis;
· forensics;
· environmental sciences;
· applied physics;
· and material science.
