Fluorescence Imaging - Recent Advances and Applications, Dr. Raffaello Papadakis, Editör, intechopen, Zagreb, ss.1-14, 2023
Chemosensors for anions and cations detections have been extensively used in
several disciplines, including pharmacology, environmental science, biology, and
chemistry. This field which is a division of supramolecular chemistry has been known
for more than 150 years. It deals with chemosensors that recognize and detect anions
and cations via optical or electrochemical signals. Today, a sustainable variety of
chemosensors are established to detect both anions and cations. Additionally, chemosensors can be used to construct a sensory device and extract, and separate anions and
cations. Chemosensors can detect toxic anions such as fluoride and cyanide as well as
cations like mercury. Thus, chemosensors have become an attractive area of supramolecular chemistry. This chapter focuses on both colorimetric and fluorometric optical
chemosensors and their application for anions and cations detections.
